Stephenson's parents emigrated to the United States when he was 2 years old; he was educated in public schools in New York, where his parents had settled, and at a Wesleyan seminary. He became a clerk in a store at 16, but in 1828 he apprenticed himself to a coachbuilder, Andrew Wade, of Broome Street, New York. His apprenticeship lasted two years, during which time he learned mechanical drawing in the evenings and started to design vehicles. He was employed for a year on carriage repair work and in 1831 he opened his own coach repair business. Within a year he had built New York's first omnibus; this was bought by Abraham Brower, Stephenson's former employer, who started the city's first bus service. Brower immediately ordered a further three buses from Stephenson, and a further horse-drawn car was ordered by the New York \& Harlem Railroad. He built the car used at the opening of the railroad on 26 November 1832, the first street railway in the world. Orders followed for cars for many street railroads in other cities in the eastern States, and business prospered until the financial panic of 1837. Stephenson's factory was forced to close but he managed to pay off his creditors in the next six years and started in business again, building only omnibuses and coaches to become recognized as the world's foremost builder of streetcars. His first car had four flanged wheels, and a body of three compartments slung on leather straps from an unsprung chassis. He built horse-drawn cars, cable cars, electric and open cars; by 1891 his factory had 500 employees and was producing some twenty-five cars a week. His first patent had been dated 23 April 1833 and was followed by some ten others. During the Civil War, his factory was turned over to the manufacture of pontoons and gun carriages. He married Julia Tiemann in 1833; they had two sons and a daughter. He lived at New Rochelle, New York, from 1865 until his death.

As a Jewish boy in Russia, Sarnoff spent several years preparing to be a Talmudic Scholar, but in 1900 the family emigrated to the USA and settled in Albany, New York. While at public school and at the Pratt Institute in Brooklyn, New York, he helped the family finances by running errands, selling newspapers and singing the liturgy in the synagogue. After a short period as a messenger boy with the Commercial Cable Company, in 1906 he became an office boy with the Marconi Wireless Telegraph Company of America (see G. Marconi). Having bought a telegraph instrument with his first earnings, he taught himself Morse code and was made a junior telegraph operator in 1907. The following year he became a wireless operator at Nantucket Island, then in 1909 he became Manager of the Marconi station at Sea Gate, New York. After two years at sea he returned to a shore job as wireless operator at the world's most powerful station at Wanamaker's store in Manhattan. There, on 14 April 1912, he picked up the distress signals from the sinking iner Titanic, remaining at his post for three days.

Rewarded by rapid promotion (Chief Radio Inspector 1913, Contract Manager 1914, Assistant Traffic Manager 1915, Commercial Manager 1917) he proposed the introduction of commercial radio broadcasting, but this received little response. Consequently, in 1919 he took the job of Commercial Manager of the newly formed Radio Corporation of America (RCA), becoming General Manager in 1921, Vice- President in 1922, Executive Vice-President in 1929 and President in 1930. In 1921 he was responsible for the broadcasting of the Dempsey-Carpentier title-fight, as a result of which RCA sold $80 million worth of radio receivers in the following three years. In 1926 he formed the National Broadcasting Company (NBC). Rightly anticipating the development of television, in 1928 he inaugurated an experimental NBC television station and in 1939 demonstrated television at the New York World Fair. Because of his involvement with the provision of radio equipment for the armed services, he was made a lieutenant-colonel in the US Signal Corps Reserves in 1924, a full colonel in 1931 and, while serving as a communications consultant to General Eisenhower during the Second World War, Brigadier General in 1944.

With the end of the war, RCA became a major manufacturer of television receivers and then invested greatly in the ultimately successful development of shadowmask tubes and receivers for colour television. Chairman and Chief Executive from 1934, Sarnoff held the former post until his retirement in 1970.

The son of Marc Isambard Brunel and Sophia Kingdom, he was educated at a private boarding-school in Hove. At the age of 14 he went to the College of Caen and then to the Lycée Henri-Quatre in Paris, after which he was apprenticed to Louis Breguet. In 1822 he returned from France and started working in his father's office, while spending much of his time at the works of Maudslay, Sons \& Field.

From 1825 to 1828 he worked under his father on the construction of the latter's Thames Tunnel, occupying the position of Engineer-in-Charge, exhibiting great courage and presence of mind in the emergencies which occurred not infrequently. These culminated in January 1828 in the flooding of the tunnel and work was suspended for seven years. For the next five years the young engineer made abortive attempts to find a suitable outlet for his talents, but to little avail. Eventually, in 1831, his design for a suspension bridge over the River Avon at Clifton Gorge was accepted and he was appointed Engineer. (The bridge was eventually finished five years after Brunel's death, as a memorial to him, the delay being due to inadequate financing.) He next planned and supervised improvements to the Bristol docks. In March 1833 he was appointed Engineer of the Bristol Railway, later called the Great Western Railway. He immediately started to survey the route between London and Bristol that was completed by late August that year. On 5 July 1836 he married Mary Horsley and settled into 18 Duke Street, Westminster, London, where he also had his office. Work on the Bristol Railway started in 1836. The foundation stone of the Clifton Suspension Bridge was laid the same year. Whereas George Stephenson had based his standard railway gauge as 4 ft 8½ in (1.44 m), that or a similar gauge being usual for colliery wagonways in the Newcastle area, Brunel adopted the broader gauge of 7 ft (2.13 m). The first stretch of the line, from Paddington to Maidenhead, was opened to traffic on 4 June 1838, and the whole line from London to Bristol was opened in June 1841. The continuation of the line through to Exeter was completed and opened on 1 May 1844. The normal time for the 194-mile (312 km) run from Paddington to Exeter was 5 hours, at an average speed of 38.8 mph (62.4 km/h) including stops. The Great Western line included the Box Tunnel, the longest tunnel to that date at nearly two miles (3.2 km).

Brunel was the engineer of most of the railways in the West Country, in South Wales and much of Southern Ireland. As railway networks developed, the frequent break of gauge became more of a problem and on 9 July 1845 a Royal Commission was appointed to look into it. In spite of comparative tests, run between Paddington-Didcot and Darlington-York, which showed in favour of Brunel's arrangement, the enquiry ruled in favour of the narrow gauge, 274 miles (441 km) of the former having been built against 1,901 miles (3,059 km) of the latter to that date. The Gauge Act of 1846 forbade the building of any further railways in Britain to any gauge other than 4 ft 8 1/2 in (1.44 m).

The existence of long and severe gradients on the South Devon Railway led to Brunel's adoption of the atmospheric railway developed by Samuel Clegg and later by the Samuda brothers. In this a pipe of 9 in. (23 cm) or more in diameter was laid between the rails, along the top of which ran a continuous hinged flap of leather backed with iron. At intervals of about 3 miles (4.8 km) were pumping stations to exhaust the pipe. Much trouble was experienced with the flap valve and its lubrication—freezing of the leather in winter, the lubricant being sucked into the pipe or eaten by rats at other times—and the experiment was abandoned at considerable cost.

Brunel is to be remembered for his two great West Country tubular bridges, the Chepstow and the Tamar Bridge at Saltash, with the latter opened in May 1859, having two main spans of 465 ft (142 m) and a central pier extending 80 ft (24 m) below high water mark and allowing 100 ft (30 m) of headroom above the same. His timber viaducts throughout Devon and Cornwall became a feature of the landscape. The line was extended ultimately to Penzance.

As early as 1835 Brunel had the idea of extending the line westwards across the Atlantic from Bristol to New York by means of a steamship. In 1836 building commenced and the hull left Bristol in July 1837 for fitting out at Wapping. On 31 March 1838 the ship left again for Bristol but the boiler lagging caught fire and Brunel was injured in the subsequent confusion. On 8 April the ship set sail for New York (under steam), its rival, the 703-ton Sirius, having left four days earlier. The 1,340-ton Great Western arrived only a few hours after the Sirius. The hull was of wood, and was copper-sheathed. In 1838 Brunel planned a larger ship, some 3,000 tons, the Great Britain, which was to have an iron hull.

The Great Britain was screwdriven and was launched on 19 July 1843,289 ft (88 m) long by 51 ft (15.5 m) at its widest. The ship's first voyage, from Liverpool to New York, began on 26 August 1845. In 1846 it ran aground in Dundrum Bay, County Down, and was later sold for use on the Australian run, on which it sailed no fewer than thirty-two times in twenty-three years, also serving as a troop-ship in the Crimean War. During this war, Brunel designed a 1,000-bed hospital which was shipped out to Renkioi ready for assembly and complete with shower-baths and vapour-baths with printed instructions on how to use them, beds and bedding and water closets with a supply of toilet paper! Brunel's last, largest and most extravagantly conceived ship was the Great Leviathan, eventually named The Great Eastern, which had a double-skinned iron hull, together with both paddles and screw propeller. Brunel designed the ship to carry sufficient coal for the round trip to Australia without refuelling, thus saving the need for and the cost of bunkering, as there were then few bunkering ports throughout the world. The ship's construction was started by John Scott Russell in his yard at Millwall on the Thames, but the building was completed by Brunel due to Russell's bankruptcy in 1856. The hull of the huge vessel was laid down so as to be launched sideways into the river and then to be floated on the tide. Brunel's plan for hydraulic launching gear had been turned down by the directors on the grounds of cost, an economy that proved false in the event. The sideways launch with over 4,000 tons of hydraulic power together with steam winches and floating tugs on the river took over two months, from 3 November 1857 until 13 January 1858. The ship was 680 ft (207 m) long, 83 ft (25 m) beam and 58 ft (18 m) deep; the screw was 24 ft (7.3 m) in diameter and paddles 60 ft (18.3 m) in diameter. Its displacement was 32,000 tons (32,500 tonnes).

The strain of overwork and the huge responsibilities that lay on Brunel began to tell. He was diagnosed as suffering from Bright's disease, or nephritis, and spent the winter travelling in the Mediterranean and Egypt, returning to England in May 1859. On 5 September he suffered a stroke which left him partially paralysed, and he died ten days later at his Duke Street home.

Soon after his birth, Senefelder's family moved to Mannheim, where his father, an actor, had obtained a position in the state theatre. He was educated there, until he gained a scholarship to the university of Ingolstadt. The young Senefelder wanted to follow his father on to the stage, but the latter insisted that he study law. He nevertheless found time to write short pieces for the theatre. One of these, when he was 18 years old, was an encouraging success. When his father died in 1791, he gave up his studies and took to a new life as poet and actor. However, the wandering life of a repertory actor palled after two years and he settled for the more comfortable pursuit of playwriting. He had some of his work printed, which acquainted him with the art of printing, but he fell out with his bookseller. He therefore resolved to carry out his own printing, but he could not afford the equipment of a conventional letterpress printer. He began to explore other ways of printing and so set out on the path that was to lead to an entirely new method.

He tried writing in reverse on a copper plate with some acid-resisting material and etching the plate, to leave a relief image that could then be inked and printed. He knew that oily substances would resist acid, but it required many experiments to arrive at a composition of wax, soap and charcoal dust dissolved in rainwater. The plates wore down with repeated polishing, so he substituted stone plates. He continued to etch them and managed to make good prints with them, but he went on to make the surprising discovery that etching was unnecessary. If the image to be printed was made with the oily composition and the stone moistened, he found that only the oily image received the ink while the moistened part rejected it. The printing surface was neither raised (as in letterpress printing) nor incised (as in intaglio printing): Senefelder had discovered the third method of printing.

He arrived at a workable process over the years 1796 to 1799, and in 1800 he was granted an English patent. In the same year, lithography (or "writing on stone") was introduced into France and Senefelder himself took it to England, but it was some time before it became widespread; it was taken up by artists especially for high-quality printing of art works. Meanwhile, Senefelder improved his techniques, finding that other materials, even paper, could be used in place of stone. In fact, zinc plates were widely used from the 1820s, but the name "lithography" stuck. Although he won world renown and was honoured by most of the crowned heads of Europe, he never became rich because he dissipated his profits through restless experimenting.

With the later application of the offset principle, initiated by Barclay, lithography has become the most widely used method of printing.

Details of Biro's early life are obscure, but by 1939 he had been active as a painter, a member of the Hungarian Academy of Sciences and an inventor, patenting over thirty minor inventions. During the 1930s he edited a cultural magazine and noticed in the printing shop the advantages of quick-drying ink. He began experimenting with crude ballpoint pens. The idea was not new, for an American, John Loud, had patented a cumbersome form of pen for marking rough surfaces in 1888; it had failed commercially. Biro and his brother Georg patented a ballpoint pen in 1938, although they had not yet perfected a suitable ink or a reservoir to hold it.

In 1940 Biro fled the Nazi occupation of Hungary and settled in Argentina. Two years later, he had developed his pen to the point where he could seek backers for a company to exploit it commercially. His principal backer appears to have been an English accountant, Henry George Martin. In 1944 Martin offered the invention to the US Army Air Force and the British Royal Air Force to overcome the problems aircrews were experiencing at high altitudes with leaking fountain pens. Some 10,000 ballpoints were made for the RAF. Licences were granted in the USA for the manufacture of the "biro", and in 1944 the Miles-Martin Pen Company was formed in Britain and began making them on a large scale at a factory near Reading, Berkshire; by 1951 its workforce had grown to over 1,000. Other companies followed suit; by varying details of the pen, they avoided infringing the original patents. One such entrepreneur, Miles Reynolds, was the first to put the pen on sale to the public in New York; it is reputed that 10,000 were sold on the first day.

Biro had little taste for commercial exploitation, and by 1947 he had withdrawn from the Argentine company, mainly to resume his painting, in the surrealist style. Examples of his work are exhibited in the Fine Arts Museum in Budapest. He created an instrument that had a greater impact on written communication than any other single invention.

Huygens was born into a cultured and privileged class. His father, Constantijn, was a poet and statesman who had wide interests. Constantijn exerted a strong influence on his son, who was educated at home until he reached the age of 16. Christiaan studied law and mathematics at Ley den University from 1645 to 1647, and continued his studies at the Collegium Arausiacum in Breda until 1649. He then lived at The Hague, where he had the means to devote his time entirely to study. In 1666 he became a Member of the Académie des Sciences in Paris and settled there until his return to The Hague in 1681. He also had a close relationship with the Royal Society and visited London on three occasions, meeting Newton on his last visit in 1689. Huygens had a wide range of interests and made significant contributions in mathematics, astronomy, optics and mechanics. He also made technical advances in optical instruments and horology.

Despite the efforts of Burgi there had been no significant improvement in the performance of ordinary clocks and watches from their inception to Huygens's time, as they were controlled by foliots or balances which had no natural period of oscillation. The pendulum appeared to offer a means of improvement as it had a natural period of oscillation that was almost independent of amplitude. Galileo Galilei had already pioneered the use of a freely suspended pendulum for timing events, but it was by no means obvious how it could be kept swinging and used to control a clock. Towards the end of his life Galileo described such a. mechanism to his son Vincenzio, who constructed a model after his father's death, although it was not completed when he himself died in 1642. This model appears to have been copied in Italy, but it had little influence on horology, partly because of the circumstances in which it was produced and possibly also because it differed radically from clocks of that period. The crucial event occurred on Christmas Day 1656 when Huygens, quite independently, succeeded in adapting an existing spring-driven table clock so that it was not only controlled by a pendulum but also kept it swinging. In the following year he was granted a privilege or patent for this clock, and several were made by the clockmaker Salomon Coster of The Hague. The use of the pendulum produced a dramatic improvement in timekeeping, reducing the daily error from minutes to seconds, but Huygens was aware that the pendulum was not truly isochronous. This error was magnified by the use of the existing verge escapement, which made the pendulum swing through a large arc. He overcame this defect very elegantly by fitting cheeks at the pendulum suspension point, progressively reducing the effective length of the pendulum as the amplitude increased. Initially the cheeks were shaped empirically, but he was later able to show that they should have a cycloidal shape. The cheeks were not adopted universally because they introduced other defects, and the problem was eventually solved more prosaically by way of new escapements which reduced the swing of the pendulum. Huygens's clocks had another innovatory feature: maintaining power, which kept the clock going while it was being wound.

Pendulums could not be used for portable timepieces, which continued to use balances despite their deficiencies. Robert Hooke was probably the first to apply a spring to the balance, but his efforts were not successful. From his work on the pendulum Huygens was well aware of the conditions necessary for isochronism in a vibrating system, and in January 1675, with a flash of inspiration, he realized that this could be achieved by controlling the oscillations of the balance with a spiral spring, an arrangement that is still used in mechanical watches. The first model was made for Huygens in Paris by the clockmaker Isaac Thuret, who attempted to appropriate the invention and patent it himself. Huygens had for many years been trying unsuccessfully to adapt the pendulum clock for use at sea (in order to determine longitude), and he hoped that a balance-spring timekeeper might be better suited for this purpose. However, he was disillusioned as its timekeeping proved to be much more susceptible to changes in temperature than that of the pendulum clock.

He was the son of a merchant, Oliver Train, who had settled in New Orleans, Louisiana. His mother and sister died in a yellow fever epidemic and he was sent to live on his grandmother's farm at Waltham, Massachusetts, where he went to the district school. He left in 1843 and was apprenticed in a grocery store in nearby Cambridge, where, one day, a relative named Enoch Train called to see him. George Train left and went to join his relative's shipping office across the river in Boston; Enoch Train, among other enterprises, ran a packet line to Liverpool and, in 1850, sent George to England to manage his Liverpool office. Three years later, George Train went to Melbourne, Australia, and established his own shipping firm; he is said to have earned £95,000 in his first year there. In 1855 he left Australia to travel in Europe and the Levant where he made many contacts. In the late 1850s and early 1860s he was in England seeking capital for American railroads and promoting the construction of street railways or trams in Liverpool, London and Staffordshire. In 1862 he was back in Boston, where he was put in jail for disturbing a public meeting; in 1870, he achieved momentary fame for travelling around the world in eighty days.

Yourkevitch came from an academic family, but one without any experience or tradition of sea service. Despite this he decided to become a naval architect, and after secondary education at Moscow and engineering training at the St Petersburg Polytechnic, he graduated in 1909. For the following ten years he worked designing battleships and later submarines, mostly at the Baltic Shipyard in St Petersburg. Around 1910 he became a full member of the Russian Naval Constructors Corps, and in 1915 he was a founder member and first Scientific Secretary of the Society of Naval Engineers.

Using the published data of the American Admiral D.W. Taylor and taking advantage of access to the Norddeutscher Lloyd Testing Tank at Bremerhaven, Yourkevitch proposed a new hull form with bulbous bow and long entrances and runs. This was the basis for the revolutionary battleships then laid down at St Petersburg, the "Borodino" class. Owing to the war these ships were launched but never completed. At the conclusion of the war Yourkevitch found himself in Constantinople, where he experienced the life of a refugee, and then he moved to Paris where he accepted almost any work on offer. Fortunately in 1928, through an introduction, he was appointed a draughtsman at the St Nazaire shipyard. Despite his relatively lowly position, he used all his personality to persuade the French company to alter the hull form of the future record breaker Normandie. The gamble paid off and Yourkevitch was able to set up his own naval architecture company, BECNY, which designed many well-known liners, including the French Pasteur.

In 1939 he settled in North America, becoming a US citizen in 1945. On the night of the fire on the Normandie, he was in New York but was prevented from going close to the ship by the police, and the possibility of saving the ship was thrown away. He was involved in many projects as well as lecturing at Ann Arbor, Michigan, and at the Massachusetts Institute of Technology. He maintained connections with his technical colleagues in St Petersburg in the later years of his life. His unfulfilled dream was the creation of a superliner to carry 5,000 passengers and thus able to make dramatic cuts in the cost of transatlantic travel. Yourkevitch was a fine example of a man whose vision enabled him to serve science and engineering without consideration of inter-national boundaries.

The son of a barber, Glauber took up the study of alchemy and travelled widely in search of its secrets. Around 1639, the political uncertainties of the Thirty Years War persuaded him to leave Germany for a more settled life in Amsterdam. While there, he carried out most of the practical work for which he is famous, including his distillation furnace, which made it possible to reach higher temperatures and to heat substances in a variety of conditions. To earn a living he set up in the wine trade, but he continued his alchemical pursuits, under cover on account of the unpopularity of the would-be gold makers. After the end of the war, he returned to Germany, but in 1655 personal disputes and religious friction drove him back to Amsterdam. He set about constructing the largest and most elaborate chemical laboratory in Europe.

Glauber's best-known writing, the Furni novi philosophici (1646–9) gives the clearest idea of his practical methods and was influential on some of the leading chemists of the time and later. His name survives today in Glauber's salt for hydrated sodium sulphate. Glauber described several methods for preparing the mineral acids, materials of great importance to the chemist, and obtained the concentrated acids by using his distilling furnace. He tried distilling any substance he could lay hands on, and in the course of this work became probably the first chemist to distil coal and, using hydrochloric acid, obtain benzene and phenol. Glauber was the best practical chemist of the age and the first industrial chemist.

McAdam was the son of one of the founder of the first bank in Ayr. As an infant, he nearly died in a fire which destroyed the family's house of Laywyne, in Carsphairn parish; the family then moved to Blairquhan, near Straiton. Thence he went to the parish school in Maybole, where he is said to have made a model section of a local road. In 1770, when his father died, he was sent to America where he was brought up by an uncle who was a merchant in New York. He stayed in America until the close of the revolution, becoming an agent for the sale of prizes and managing to amass a considerable fortune. He returned to Scotland where he settled at Sauchrie in Ayrshire. There he was a magistrate, Deputy-Lieutenant of the county and a road trustee, spending thirteen years there. In 1798 he moved to Falmouth in Devon, England, on his appointment as agent for revictualling of the Royal Navy in western ports.

He continued the series of experiments started in Ayrshire on the construction of roads. From these he concluded that a road should be built on a raised foundation with drains formed on either side, and should be composed of a number of layers of hard stone broken into angular fragments of roughly cubical shape; the bottom layer would be larger rocks, with layers of progressively smaller rocks above, all bound together with fine gravel. This would become compacted and almost impermeable to water by the action of the traffic passing over it. In 1815 he was appointed Surveyor-General of Bristol's roads and put his theories to the test.

In 1823 a Committee of the House of Commons was appointed to consider the use of "macadamized" roads in larger towns; McAdam gave evidence to this committee, and it voted to give him £10,000 for his past work. In 1827 he was appointed Surveyor-General of Roads and moved to Hoddesdon, Hertfordshire. From there he made yearly visits to Scotland and it was while returning from one of these that he died, at Moffat in the Scottish Borders. He had married twice, both times to American women; his first wife was the mother of all seven of his children.

McAdam's method of road construction was much cheaper than that of Thomas Telford, and did much to ease travel and communications; it was therefore adopted by the majority of Turnpike Trusts in Britain, and the macadamization process quickly spread to other countries.

Born in Poland, Rickover was brought to the United States early in his life by his father, who settled in Chicago as a tailor. Commissioned into the US Navy in 1922, he specialized in electrical engineering (graduating from the US Naval Postgraduate School, Columbia, in 1929), quali-fied as a Submariner in 1931 and then held various posts until appointed Head of the Electrical Section of the Bureau of Ships in 1939. He held this post until the end of the Second World War.

Rickover was involved briefly in the "Manhattan" atomic bomb project before being assigned to an atomic energy submarine project in 1946. Ultimately he was made responsible for the development and building of the world's first nuclear submarine, the USS Nautilus. He was convinced of the need to make the nuclear submarine an instrument of strategic importance, and this led to the development of the ballistic missile submarine and the Polaris programme.

Throughout his career he was no stranger to controversy; indeed, his remaining on the active service list as a full admiral until the age of 82 (when forced to retire on the direct intervention of the Navy Secretary) indicates a man beyond the ordinary. He imposed his will on all around him and backed it with a brilliant and clear-thinking brain; his influence was even felt by the Royal Navy during the building of the first British nuclear submarine, HMS Dreadnought. He made many friends, but he also had many detractors.

The son of a Polish lumberjack who had settled in Russia, Tsiolkovsky was a largely self-educated schoolteacher who was practically deaf from childhood. In spite of this handicap, he studied the problems of space and spaceflight and arrived at most of the correct theoretical solutions. In 1883 he noted that the gas escaping from a vehicle moving into space would drive the containing vehicle away from it. He wrote a remarkable series of technical articles and papers including, in 1903, a seminal article, "Exploration of Space with Reactive Devices". His aerodynamic experiments did not receive any significant recognition from the Academy of Sciences, and his design for an all-metal dirigible was largely ignored at the 1914 Aeronautics Congress in St Petersburg. However, from the inception of the Soviet Union until his death, Tsiolkovsky continued his research with state support, and on 9 November 1921 he was granted a pension for life by the Council of the People's Commissars. He has rightly been described as the "Grandfather of Spaceflight" and as a fine theoretical engineer who established most of the principles upon which rocket technology is based.

She was born Sarah Breedlove in rural Louisiana, but she moved to St Louis, Mississippi, and settled there, first earning a living as a washerwoman. That occupation did not satisfy her for long, however; she saw a need among black women to smarten their appearance to improve their chances in city life, and by 1905 she had concocted a mixture that could straighten and groom black women's hair. She began to market her product in Denver, Colorado, under her married name, Madame C.J.Walker. After five further years of intensive marketing and persuading black women that they needed this product, she was able to establish her headquarters in Indianapolis for the national distribution of her hair and cosmetic products. She also set up beauty salons, which were especially successful in Harlem, New York.
