Jac Nellemann

Jacob 'Jac' Nellemann (19 April 1944 - Present): Danish racing driver who won the 1976 and 1977 Danish Formula 3 championships and participated in the 1976 Swedish Grand Prix with RAM Racing. His single Formula One entry saw him attempt to qualify in two cars—a Brabham BT42 and a BT44B—but he failed to qualify. He was on the entry list for the following year's race but was not present for qualifying. Beyond his F1 attempt, Nellemann comes from a motorsport family—his father raced in sportscars while his uncle Robert won the Danish Formula 3 title eight times.

After his racing career, Jac became a hugely successful historic racer, sells Aston Martin cars and Honda motorbikes, works as a publisher, and runs the Copenhagen Historic Grand Prix in August every year. He is one of the lesser-known drivers in Formula 1 history, having never successfully qualified for or started a Grand Prix race.
