Edward Payson Bullard served his apprenticeship at the Whitin Machine Works, Whitinsville, Massachusetts, and worked at the Colt Armory in Hartford, Connecticut, until 1863; he then entered the employ of Pratt \& Whitney, also in Hartford. He later formed a partnership with J.H.Prest and William Parsons manufacturing millwork and tools, the firm being known as Bullard \& Prest. In 1866 Bullard organized the Norwalk Iron Works Company of Norwalk, Connecticut, but afterwards withdrew and continued the business in Hartford. In 1868 the firm of Bullard \& Prest was dissolved and Bullard became Superintendent of a large machine shop in Athens, Georgia. He later organized the machine tool department of Post \& Co. at Cincinnati, and in 1872 he was made General Superintendent of the Gill Car Works at Columbus, Ohio. In 1875 he established a machinery business in Beekman Street, New York, under the name of Allis, Bullard \& Co. Mr Allis withdrew in 1877, and the Bullard Machine Company was organized.

In 1880 Bullard secured entire control of the business and also became owner of the Bridgeport Machine Tool Works, Bridgeport, Connecticut. In 1883 he designed his first vertical boring and turning mill with a single head and belt feed and a 37 in. (94 cm) capacity; this was the first small boring machine designed to do the accurate work previously done on the face plate of a lathe. In 1889 Bullard gave up his New York interests and concentrated his entire attention on manufacturing at Bridgeport, the business being incorporated in 1894 as the Bullard Machine Tool Company. The company specialized in the construction of boring machines, the design being developed so that it became essentially a vertical turret lathe. After Bullard's death, his son Edward Payson Bullard II (b. 10 July 1872 Columbus, Ohio, USA; d. 26 June 1953 Fairfield, Connecticut, USA) continued as head of the company and further developed the boring machine into a vertical multi-spindle automatic lathe which he called the "Mult-au-matic" lathe. Both father and son were members of the American Society of Mechanical Engineers.

Francis A.Pratt served an apprenticeship as a machinist with Warren Aldrich, and on completing it in 1848 he entered the Gloucester Machine Works as a journeyman machinist. From 1852 to 1854 he worked at the Colt Armory in Hartford, Connecticut, where he met his future partner, Amos Whitney. He then became Superintendent of the Phoenix Iron Works, also at Hartford and run by George S.Lincoln \& Company. While there he designed the well-known "Lincoln" miller, which was first produced in 1855. This was a development of the milling machine built by Robbins \& Lawrence and designed by F.W. Howe, and incorporated a screw drive for the table instead of the rack and pinion used in the earlier machine.

Whitney also moved to the Phoenix Iron Works, and in 1860 the two men started in a small way doing machine work on their own account. In 1862 they took a third partner, Monroe Stannard, and enlarged their workshop. The business continued to expand, but Pratt and Whitney remained at the Phoenix Iron Works until 1864 and in the following year they built their first new factory. The Pratt \& Whitney Company was incorporated in 1869 with a capital of $350,000, F.A.Pratt being elected President. The firm specialized in making machine tools and tools particularly for the armament industry. In the 1870s Pratt made no less than ten trips to Europe gaining orders for equipping armouries in many different countries. Pratt \& Whitney was one of the leading firms developing the system of interchangeable manufacture which led to the need to establish national standards of measurement. The Rogers-Bond Comparator, developed with the backing of Pratt \& Whitney, played an important part in the establishment of these standards, which formed the basis of the gauges of many various types made by the firm. Pratt remained President of the company until 1898, after which he served as their Consulting Engineer for a short time before retiring from professional life. He was granted a number of patents relating to machine tools. He was a founder member of the American Society of Mechanical Engineers in 1880 and was elected a vice-president in 1881. He was an alderman of the city of Hartford.

Amos Whitney was a member of the same distinguished family as Eli Whitney. His father was a locksmith and machinist and he was apprenticed at the age of 14 to the Essex Machine Company of Lawrence, Massachusetts. In 1850 both he and his father were working at the Colt Armory in Hartford, Connecticut, where he first met his future partner, F.A. Pratt. They both subsequently moved to the Phoenix Iron Works, also at Hartford, and in 1860 they started in a small way doing machine work on their own account. In 1862 they took a third partner, Monroe Stannard, and enlarged their workshop. The business continued to expand, but Pratt and Whitney remained at the Phoenix Iron Works until 1864 and in the following year they built their first new factory.

Amos Whitney was made Vice-President of Pratt \& Whitney Company in 1893 and was President from 1898 until 1901, when the company was acquired by the Niles- Bement-Pond Company: he then remained as one of the directors. He was elected a Member of the American Society of Mechanical Engineers in 1913.

Edward Geisler Herbert was educated at Nottingham High School in 1876–87, and at University College, London, in 1887–90, graduating with a BSc in Physics in 1889 and remaining for a further year to take an engineering course. He began his career as a premium apprentice at the Nottingham works of Messrs James Hill \& Co, manufacturers of lace machinery. In 1892 he became a partner with Charles Richardson in the firm of Richardson \& Herbert, electrical engineers in Manchester, and when this partnership was dissolved in 1895 he carried on the business in his own name and began to produce machine tools. He remained as Managing Director of this firm, reconstituted in 1902 as a limited liability company styled Edward G.Herbert Ltd, until his retirement in 1928. He was joined by Charles Fletcher (1868–1930), who as joint Managing Director contributed greatly to the commercial success of the firm, which specialized in the manufacture of small machine tools and testing machinery.

Around 1900 Herbert had discovered that hacksaw machines cut very much quicker when only a few teeth are in operation, and in 1902 he patented a machine which utilized this concept by automatically changing the angle of incidence of the blade as cutting proceeded. These saws were commercially successful, but by 1912, when his original patents were approaching expiry, Herbert and Fletcher began to develop improved methods of applying the rapid-saw concept. From this work the well-known Rapidor and Manchester saws emerged soon after the First World War. A file-testing machine invented by Herbert before the war made an autographic record of the life and performance of the file and brought him into close contact with the file and tool steel manufacturers of Sheffield. A tool-steel testing machine, working like a lathe, was introduced when high-speed steel had just come into general use, and Herbert became a prominent member of the Cutting Tools Research Committee of the Institution of Mechanical Engineers in 1919, carrying out many investigations for that body and compiling four of its Reports published between 1927 and 1933. He was the first to conceive the idea of the "tool-work" thermocouple which allowed cutting tool temperatures to be accurately measured. For this advance he was awarded the Thomas Hawksley Gold Medal of the Institution in 1926.

His best-known invention was the Pendulum Hardness Tester, introduced in 1923. This used a spherical indentor, which was rolled over, rather than being pushed into, the surface being examined, by a small, heavy, inverted pendulum. The period of oscillation of this pendulum provided a sensitive measurement of the specimen's hardness. Following this work Herbert introduced his "Cloudburst" surface hardening process, in which hardened steel engineering components were bombarded by steel balls moving at random in all directions at very high velocities like gaseous molecules. This treatment superhardened the surface of the components, improved their resistance to abrasion, and revealed any surface defects. After bombardment the hardness of the superficially hardened layers increased slowly and spontaneously by a room-temperature ageing process. After his retirement in 1928 Herbert devoted himself to a detailed study of the influence of intense magnetic fields on the hardening of steels.

Herbert was a member of several learned societies, including the Manchester Association of Engineers, the Institute of Metals, the American Society of Mechanical Engineers and the Institution of Mechanical Engineers. He retained a seat on the Board of his company from his retirement until the end of his life.
