There is not much early information at all on this company. We do know it was located at 1569 Niagara Street, Buffalo NY 14213 in 1908 and prior, before the move to Niagara St.. The picture of the Bergman factory below is from the website Preservation Ready.
We found this article from Domestic Engineering and the Journal of Mechanical Contracting, Volume 47 and dated May, 1909 noting that Bergman has moved from 102 Seneca St. to it's new factory at 1573-75 Niagara St.

We were able to find an article from The Evening Tribune (Hornell, NY) on 4/10/1923 stating that neighbors on Niagara street were complaining about the trip hammer at Bergman. The complaint was that "It is a nuisance and stops their clocks."
In 1918, Bergman is listed as a manufacturer of boring tools, tool handles (file) and pipe wrenches (Queen City Improved).

The EPA reports that the last inspection for environmental compliance was conducted on September 14, 1997 giving us a clue as to their end. The New York corporation database records the company being merged out on October 2, 2002, possibly by American Tool Companies, Inc. of Chicago.
