Jo Vonlanthen

Racing for Swiss, Jo Vonlanthen competed at the highest level of motorsport. Made a single formula 1 world championship start, driving a williams in 1975. he was 33 years old that season, and the outing brought neither points nor a classified championship position.

His name thus belongs to the sizeable group of drivers whose Grand Prix careers began and ended within a single event, a reminder of how difficult it was to convert one opportunity into a lasting seat in the mid-1970s.
