Froude was educated at a preparatory school at Buckfastleigh, and then at Westminster School, London, before entering Oriel College, Oxford, to read mathematics and classics. Between 1836 and 1838 he served as a pupil civil engineer, and then he joined the staff of Isambard Kingdom Brunel on various railway engineering projects in southern England, including the South Devon Atmospheric Railway. He retired from professional work in 1846 and lived with his invalid father at Dartington Parsonage. The next twenty years, while apparently unproductive, were important to Froude as he concentrated his mind on difficult mathematical and scientific problems. Froude married in 1839 and had five children, one of whom, Robert Edmund Froude (1846–1924), was to succeed him in later years in his research work for the Admiralty. Following the death of his father, Froude moved to Paignton, and there commenced his studies on the resistance of solid bodies moving through fluids. Initially these were with hulls towed through a house roof storage tank by wires taken over a pulley and attached to falling weights, but the work became more sophisticated and was conducted on ponds and the open water of a creek near Dartmouth. Froude published work on the rolling of ships in the second volume of the Transactions of the then new Institution of Naval Architects and through this became acquainted with Sir Edward Reed. This led in 1870 to the Admiralty's offer of £2,000 towards the cost of an experimental tank for ship models at Torquay. The tank was completed in 1872 and tests were carried out on the model of HMS Greyhound following full-scale towing trials which had commenced on the actual ship the previous year. From this Froude enunciated his Law of Comparisons, which defines the rules concerning the relationship of the power required to move geometrically similar floating bodies across fluids. It enabled naval architects to predict, from a study of a much less expensive and smaller model, the resistance to motion and the power required to move a full-size ship. The work in the tank led Froude to design a model-cutting machine, dynamometers and machinery for the accurate ruling of graph paper. Froude's work, and later that of his son, was prodigious and covered many fields of ship design, including powering, propulsion, rolling, steering and stability. In only six years he had stamped his academic authority on the new science of hydrodynamics, served on many national committees and corresponded with fellow researchers throughout the world. His health suffered and he sailed for South Africa to recuperate, but he contracted dysentery and died at Simonstown. He will be remembered for all time as one of the greatest "fathers" of naval architecture.

He was the son of a basketmaker, Philip Tonisz Leeuwenhoek, and Grietje Jacobsdr van den Berch, a brewer's daughter. After the death of his father in 1637, his mother married the painter Jacob Jansz Molijn. He went to school at Warmond and, later to an uncle who was Sheriff of Benthuizen. In 1648 he went to Amsterdam, where he was placed in a linen-draper's shop owned by William Davidson, a Scottish merchant. In 1652 or 1653 he moved back to Delft, where in 1654 he married the daughter of a cloth-merchant, Barbara de Mey. They had five children, only one of whom survived (born 22 September 1656). At about this time he bought a house and shop in the Hippolytus buurt and set up in business as a draper and haberdasher. His wife died in 1666 and in 1671 he married Cornelia Swalmius, a Reformed Church minister's daughter. Lacking self-confidence and not knowing Latin, the scientific language of the day, he was reluctant to publish the results of his investigations into a multitude of natural objects. His observations were made with single-lens microscopes made by himself. (He made at least 387 microscopes with magnifications of between 30x and 266x.) Among the subjects he studied were the optic nerve of a cow, textile fibres, plant seeds, a spark from a tinderbox, the anatomy of mites and insects' blood corpuscles, semen and spermatozoa. It was the physician Reinier de Graaf who put him in touch with the Royal Society in London, with whom he corresponded for fifty years from 1673. One of his last letters, in 1723, to the Royal Society was about the histology of the rare disease of the diaphragm that he had studied in sheep and oxen and from which he died. In public service he was a chamberlain to the sheriffs of Delft, a surveyor and a wine-gauger, offices which together gave him an income of about 800 florins a year. Leeuwenhoek never wrote a book, but collections were published in Latin and in Dutch from his scientific letters, which numbered more than 250.

Neri entered the Church and by 1601 was a priest in the household of Alamanno Bertolini in Florence. There he met the Portuguese Sir Emanuel Ximenes, with whom he shared an interest in chemistry. The two later corresponded and the twenty-seven letters extant from Ximenes, who was living in Antwerp, are the main source of information about Neri's life. At the same time, Neri was working as a craftsman in the Medici glasshouse in Florence and then in their works at Pisa. These glasshouses had been flourishing since the fifteenth century with the help of Muranese glassmakers imported from Venice. Ximenes persuaded Neri to spend some time with the glassmakers in Antwerp, probably from 1603/4, for the correspondence breaks off at that point. A final letter in March 1611 refers to Neri's recent return to Florence. In the following year, Neri published the work by which he is known, the L'arte vetraria, the first general treatise on glassmaking. Neri's plan for a further book describing his chemical and medical experiments was thwarted by his early death. L'arte belongs to the medieval tradition of manuscript recipe books. It is divided into seven books, the first being the most interesting, dealing with the materials of glassmaking and their mixing and melting to form crystal and other colourless glasses. Other sections deal with coloured glasses and the making of enamels for goldsmiths' use. Although it was noted by Galileo Galilei (1564–1642), the book made little impression for half a century, the second edition not appearing until 1661. The first Venice edition came out two years later, with a second in 1678. Due to a decline in scientific activity in Italy at this time, L'arte had more influence elsewhere in Europe, especially England, Holland and France. It began to make a real impact with the appearance in 1662 of the English translation by Christopher Merrett (1614–95), physician, naturalist and founder member of the Royal Society. This edition included Merrett's annotations, descriptions of the tools used by English glassmakers and a translation of Agricola's short account of glassmaking in his De re metallica of 1556. Later translations were based on the Merrett translation rather than the Italian original. Ravenscroft probably used Neri's account of lead glass as a starting point for his own researches in the 1670s.

A.V.Roe served an apprenticeship at a railway works, studied marine engineering at Kings College London, served at sea as an engineer, and then took a job in the motor-car industry. His hobby was flying: after studying bird-flight, he built several flying models and in 1907 one of these won a prize offered by the Daily Mail. With the prize money he built a full-size aeroplane loosely based on the Flyer of the Wright brothers, with whom he had corresponded. In September, Roe took his biplane to the motorracing circuit at Brooklands, in Surrey, but it made only a few hops and his activities were not welcomed. Roe then moved to Essex, where he assembled his new aeroplane under the arch of a railway bridge. This was a triplane design with the engine at the front (a "tractor"), and during 1909 it made several flights (this triplane is preserved by the Science Museum in London).

In 1910 Roe and his brother Humphrey founded A.V.Roe \& Co. in Manchester, they described it the "Aviator's Storehouse". During the next three years Roe designed and built aeroplanes in Manchester, then transported them to Brooklands to fly (the authorities now made him more welcome). One of the most significant of these was his Type D tractor biplane of 1911, which led to the Avro 504 two-seater trainer of 1913. This was one of the most successful trainers of all time, as around 10,000 were built. In November 1914 a flight of Avro 504s carried out the first-ever bombing raid when they attacked German airship sheds as Friedrichshafen. A.V.Roe produced the first aeroplanes with enclosed cabins during 1912: the Type F monoplane and Type G biplane. After the war, his Avian was used for several record-breaking flights. In 1928 he sold his interest in the company bearing his name and joined forces with Saunders Ltd of Cowes, on the Isle of Wight, to found Saunders-Roe Ltd. "Saro" produced a series of flying boats, from the four-seat Cutty Sark of 1929 to the large, and ill-fated, Princess of 1952.
