Rudolf "Rudi" Fischer (19 April 1912 – 30 December 1976) was a Swiss racing driver, who competed in Formula One at seven Grands Prix from 1951 to 1952.

A crowd of 350,000 watched Paul Greifzu of Suhl, Thuringia, win in a car he built himself.

[1] In the 1952 Swiss Grand Prix, in Bern, Fischer finished second to Piero Taruffi; both drivers were in Ferraris.

Écurie Espadon was composed of a group of Swiss amateur gentleman racers.

The word "Écurie" was used at the beginning as most of the team's cars were French, generally Gordinis.
