Wichmann diesel engines were made by M. Haldorsen & Sønner Motorfrabrikk. The company was started by Martines Haldorsen in Rubbestadneset. His son, Haldor Andreas Haldorsen constructed the first engine, a single-cylinder 2 hp two-stroke engine in 1903.

The factory was sold to the Finnish group Wärtsilä in 1986.
