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

Key Information

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. His entry was taken by Wolfgang Seidel.[2] Throughout the 1960s Slotemaker competed in the 24 Hours of Le Mans race, and was a driver and advisor for the Le Mans film in 1970.

In 1956, he established his "Anti-skid" driving school at Zandvoort, which is still operating today.[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. His car spun on a patch of oil and collided with a course car parked alongside the track. Despite the relatively minor force of the accident, he suffered a broken neck and died instantly. A doctor in the course car was also injured.[4]

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

''Rob Slotemaker'' was a Dutch racing driver and dentist known for his successes in sports car racing and Formula Junior competitions during the 1950s and early 1960s. Born in Batavia in the Dutch East Indies, he moved to the Netherlands and combined his professional career as a dentist with a passion for motorsport, earning him the nickname "The Flying Dentist." He achieved notable victories, including wins in national championships and international events, before his life was tragically cut short in a racing accident at Zandvoort in 1962. Slotemaker began racing in the mid-1950s, quickly progressing to more competitive series and earning respect for his driving talent in an era of dangerous circuits and limited safety measures. His career highlighted the amateur spirit of early postwar motor racing in Europe.

Early life

Birth and background

Adriaan Robert "Sloot" Slotemaker was born on 13 June 1929 in Batavia, Dutch East Indies (now Jakarta, Indonesia), which was then the capital of a Dutch colony. He held Dutch nationality. Little is documented about his early family life or childhood in the Dutch East Indies prior to his later professional pursuits.

Military service and early driving skills

Rob Slotemaker served as a pilot in the Royal Netherlands Air Force during the 1950s. He initially trained on the de Havilland Tiger Moth in the Netherlands before continuing his flight training in the United States, where he logged 70 flying hours. Upon returning to the Netherlands, he was accepted into the air force at the rank of sergeant, a demotion from the officer status he had earned abroad, which reportedly troubled him for the rest of his life. During a cold winter in the early 1950s, when frozen runways and taxiways prevented flying operations, Slotemaker drove a car onto the closed air base surfaces covered in snow and ice to entertain colleagues, deliberately spinning the vehicle in various directions. Through these repeated experiments, he quickly learned how to correct slides and regain control, developing a practical mastery of skid behavior under low-friction conditions. This informal experience on snow and ice at air bases formed the basis for his deep understanding of vehicle dynamics in slippery conditions and informed the creation of his later anti-skid driving school.

Anti-skid driving school

Establishment and operations

Rob Slotemaker founded his anti-skid driving school, known as the Anti-Slipschool, in 1956 at the Circuit Zandvoort in the Netherlands. The school was initially established on a side road near the "Bos In" bend of the circuit. It focused on teaching drivers practical techniques for skid control and safe handling in low-grip conditions. The initiative drew directly from Slotemaker's prior experience as a fighter jet pilot, where he had practiced skid prevention on snow-covered runways during military service. By professionalizing anti-slip training, the school aimed to improve road safety and vehicle control for a broad range of drivers. The Anti-Slipschool has continued operations beyond Slotemaker's lifetime, evolving over the decades while maintaining its core emphasis on advanced skid-control instruction at Zandvoort. It now operates as RSZ Motorsport, serving as the Netherlands' primary racing and advanced driving school with facilities adjacent to the circuit entrance on Rob Slotemakerstraat.

Racing career

Early rallies and competitions

Rob Slotemaker began his competitive motorsport career in rallying during the mid-1950s, applying the advanced driving skills he developed in military service. His competition debut came in the 1954 Monte Carlo Rally, where he partnered with Erik de Stoppelaar as co-driver. Driving a Ford Zephyr, the pair successfully completed the event. This rally marked the start of Slotemaker's involvement in early 1950s competitions, primarily focused on rallying before he pursued other aspects of motorsport. Specific details on additional rallies from this period remain limited in documented records.

Sports car and touring car racing

Rob Slotemaker concentrated much of his racing career on sports cars and touring cars. He participated in the 24 Hours of Le Mans five times, with one of his most notable performances coming in 1961 when he finished 11th overall, sharing a works Triumph TR4 with Les Leston. He competed in various touring cars throughout his career, with models such as the Porsche in earlier events.

Formula One entry

Rob Slotemaker made a single attempt to enter the Formula One World Championship, at his home race, the 1962 Dutch Grand Prix held at Zandvoort. He was entered in one of Carel Godin de Beaufort's Porsche 718 cars, fielded under the Ecurie Maarsbergen banner. However, the car was not prepared in time for the event, leading Slotemaker to withdraw and not participate in practice, qualifying, or the race itself. This remained his only listed entry in a Formula One World Championship Grand Prix. His Formula One involvement thus consisted solely of this unfulfilled 1962 entry.

Film and television work

Television appearances

Rob Slotemaker made occasional television appearances as himself, typically in programs related to motorsport and automotive topics. In 1962, he appeared in one episode of the television series Formula 1, presenting himself amid his single entry into the Formula One World Championship that year. No other film or television work is documented for Rob Slotemaker, who died in 1962.

Death

On 15 July 1962, Rob Slotemaker was killed at the age of 33 during a Formula Junior race at Circuit Park Zandvoort. Driving a Lotus 22, Slotemaker lost control of his car and was involved in a collision with another competitor, resulting in fatal injuries. The crash occurred at Zandvoort, Slotemaker's home circuit where he had founded his anti-skid driving school in 1956.

Legacy

Circuit memorial

In recognition of Rob Slotemaker's enduring connection to the Circuit Zandvoort, the track renamed a key corner in his memory following his death in 1979. The right-hander situated immediately past the Hunserug corner—now known as the Slotemakerbocht—was officially given this name after 1979 to commemorate the precise location where Slotemaker suffered his fatal crash during a touring car race. The Slotemakerbocht has formed part of the Zandvoort layout since the circuit opened in 1948, but the renaming serves as a permanent memorial to Slotemaker's career and contributions as a motorsport specialist. Drivers approach this high-speed turn at significant velocity, with emphasis placed on its latter section, where the exit leads almost blindly toward the Scheivlak. Although safety features have been updated over time, including modifications still evident in 2022, the corner's challenging, sloping character remains unaltered.

Continued influence

Rob Slotemaker's anti-skid driving school at Circuit Zandvoort continues to operate, maintaining his legacy in driver training and road safety education. Founded in 1956, the facility—originally established on the inside of the circuit—has evolved significantly while remaining on the circuit grounds. In 2012, it transformed into the official BMW Driving Experience Slotemakers, the first certified BMW Driving Experience program outside Germany. The school now runs nearly year-round, closing only three days annually, and delivers a broad range of programs including skid control exercises on specialized tracks, drift training, limit-driving experiences, and tailored corporate events. This ongoing operation, spanning over 65 years in partnership with the circuit, reflects the lasting impact of Slotemaker's initiative on advancing safe driving techniques and skills development for both private individuals and professional drivers. A related entity, RSZ Autosport, which originated from the Slotemaker Slipschool in 1955, has also grown into an organizer of racing, drift courses, and track days, further extending his influence in motorsport training.

Mentorship of younger drivers

Rob Slotemaker acted as a mentor to several young Dutch racing drivers, with his most notable influence on future Formula One driver Jan Lammers. Lammers has described Slotemaker as his mentor and godfather, crediting him for recognizing his talent early and supporting his entry into competitive racing. Slotemaker took Lammers under his wing, making him one of his protégés and guiding his early career development. He provided practical support, including supplying a Simca for Lammers' debut in Group 1 touring cars in 1973, where the 16-year-old achieved victory in his first race. Drawing on his extensive racing experience, Slotemaker trained Lammers and helped shape his path to becoming a Formula One competitor and Le Mans winner.
