biography

Felt was the son of Eugene Kincaid Filz (a member of the Wisconsin State Assembly ) and Elizabeth Filz. In 1878 he trained in a mechanical engineering company in Beloit. In 1880 he learned the French language. In 1882 he moved to Chicago and worked there as a foreman of a rolling mill.

Ten-digit Victor comptometer

In 1884 he developed the prototype of a new calculating machine . He became known through this first calculator, which only worked with keys as a comptometer instead of, for example, slip wheels. Together with the businessman Robert Tarrant , he founded the Felt & Tarrant Manufacturing Company on January 25, 1889 , which was an important company in the pocket calculator industry until the mid-1970s.

After that, Felt invented other devices. He has acquired 46 domestic and 25 foreign patents.

In 1919 he acquired several hundred acres on Lake Michigan between Holland and Saugatuck and built a Shore Acres Farm there with the Dorr E. Felt Mansion from 1925/28.

Felt was married to Agnes McNulty and had four children.
