This busines was founded in about 1880 by Horatio Hobbs and Edward F. Gordon. Gordon was a well-known woodworking machinery designer who apparently continued to work at John A. White Co. even after found his own business. Hobbs, Gordon & Co. specialized primarily in steam-heating equipment: steam boilers, radiators, and valves. But they also manufactured tablesaws and radial drills.

Gordon had received an 1874 patent for a bandsaw which was manufactured by D. C. Allen & Co. of Concord. He later worked for Concord (N. H.) Machine Co., which was became part of John A. White Co.; an 1892 Manufacturer & Builder article reported that Gordon was moving to Dover as part of the buyout.
