Swiss driver Christian Kautz was born in 1913 as son of a millionaire banker in Brussels. His father's connections were a significant factor in easing Kautz's entry into motor racing. One year after arriving at Maserati in 1936, he made the move to Mercedes-Benz. Kautz reached the zenith of his career in the 1937 season driving a W 125. With Mercedes-Benz totally dominating the final season of the 750kg open-wheel class, Kautz took third place in the Grand Prix of Monaco, the same result that he was to achieve in the drivers' championship that year.
In the following campaign, with new regulations in place, he joined the rival outfit of Auto Union but failed to see the chequered flag in any of the races he contested. During the Second World War, Kautz emigrated to the United States where he worked as a test pilot for aircraft manufacturer Lockheed. After the war, Kautz returned to racing as a member of the Maserati squad. His life and career came to a tragic end in 1948 when he was involved in a fatal accident in his home race on the Bremgarten circuit.
