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.
