[2] The firm was founded in 1894 by Edward Payson Bullard Sr. (born April 18, 1841, in Uxbridge, Massachusetts, US; died December 22, 1906, in Bridgeport, Connecticut, US[3]).

[4] Bullard Sr is believed to have developed the first small boring machine designed to do the accurate work previously performed on the faceplate of a lathe.
Bullard Jr led the development of the company's multiple-spindle Mult-Au-Matic brand machine that became an important automatic lathe in the mass production of parts for the automotive industry.
