About Fred Duesenberg
Frederick Samuel Duesenberg (December 6, 1876 – July 26, 1932) was a German-born American automobile and engine designer, manufacturer and sportsman who was internationally known as a designer of racecars and racing engines. Duesenberg's engineering expertise influenced the development of the automobile, especially during the 1910s and 1920s. He is credited with introducing an eight-cylinder engine, also known as the Duesenberg Straight-8 engine, and four-wheel hydraulic brakes, a first for American cars, in addition to other mechanical innovations. Duesenberg was also patentholder of his designs for a four-wheel hydraulic brake, an early automatic transmission, and a cooling system, among others. Fred and his younger brother, August "Augie" Duesenberg, shared the patents, filed in 1913 and renewed in 1918, for their "walking beam" four-cylinder engine and the Duesenberg Straight 8 (an eight-cylinder engine with a single, overhead camshaft). In 1913 the Duesenberg brothers founded the Duesenberg Motor Company, Incorporated, which was subsequently sold, and in 1920 were among the founders of the Duesenberg Automobile and Motor Company, which manufactured passenger cars in Indianapolis, Indiana, from 1921 until 1937, including the Duesenberg Model A, the brothers' first mass-produced vehicle. Fred Duesenberg served as the chief engineer at both companies. From 1926 until his death in 1932, Fred Duesenberg focused on designs for luxury passenger cars, which included the Duesenberg models X, S, and J, while serving as vice president of engineering and later in the 1920s as president of the company. Duesenberg died from complications following a car accident in 1932; Duesenberg passenger-car production ended five years later. In addition to designing passenger cars, Fred and Augie Duesenberg were involved in auto racing for more than a decade. Although Fred was no longer driving racecars by 1912, he remained active for another twelve years as a racecar designer and team owner. In April 1920 a Duesenberg racecar driven by Tommy Milton set a land-speed record of 156.046 miles per hour (251.132 km/h) for a measured mile on the sands at Daytona Beach, Florida. In 1921 Jimmy Murphy drove a Duesenberg racer to become the first American car to win the prestigious Grand Prix at Le Mans, France. Duesenberg-made entries also participated in Indianapolis 500-mile auto races between 1912 and 1932, including winning the annual event at the Indianapolis Motor Speedway in 1924, 1925, and 1927 before Fred Duesenberg retired from racing in 1931.
