Adriaan Robert "Sloot" Slotemaker (13 June 1929 – 16 September 1979)[1] was a Dutch racing driver.

He entered one Formula One World Championship race, the 1962 Dutch Grand Prix, with one of Carel Godin de Beaufort's Porsches, but his car was not ready in time for the event.

[3] On 16 September 1979, at the Circuit Park Zandvoort, Slotemaker was killed when he crashed his Chevrolet Camaro during the "Trophy of the Dunes" touring car race.

Despite the relatively minor force of the accident, he suffered a broken neck and died instantly.

[4] A section of the circuit, the right-hander past Hunzerug, is named in his memory.
