Despite many successes in Grand Prix motor racing for Auto Union in the early 1930s, during the era of the famous "Silver Arrows", he is now mostly known for his domination of hillclimbing, which earned him the nickname "BergkÃ¶nig" or "King of the Mountains"
Also know as Hans Stuck von Villiez, Stuck was born in Warsaw in 1900 while his parents were on a business trip, although there is some uncertainty about his birth year, which some claimed to have been 1890 or 1895. Although his parents were of Swiss ancestry, they had moved to Germany by the time Stuck was born, and he grew up there.
He was called up for military service in World War I in 1917. In 1918, his older brother Walter was killed, along with Walter's commanding officer; as a result, Stuck met the commander's sister, Ellen Hahndorff, and they were married in 1922. After several years, Stuck's involvement in the fast life off the track as well as on caused them to split up and divorce.
In 1931, he met Paula von Reznicek, a famous tennis player; they were married in 1932. The fact that she had a Jewish grandfather caused Stuck some problems with the rise of the Nazis, but his personal relationship with Hitler saved him from serious trouble.
In 1939, he met Christa Thielmann, at that point engaged to Paula's youngest brother. Stuck and Paula divorced in 1948, and he married Christa that year. Their son, Hans Joachim, was born in 1951.
Stuck's experience with car racing started in 1922 with early morning runs bringing milk from his farm to Munich, shortly after his first marriage. This eventually led to his taking up hill-climbing; he won his first race, at Baden-Baden, in 1923.
A few years later, after a year as a privateer for Austro-Daimler, he became a works driver for them in 1927, doing well in hill climbs, and making his first appearance in a circuit race (the German Grand Prix) that year as well. In 1931, Austro-Daimler left racing, and Stuck eventually wound up driving a Mercedes-Benz SSKL in sports car racing, where he continued to excel.
In 1933, his acquaintance with Adolf Hitler (whom he had met by chance on a hunting trip in 1925) led to his involvement with Ferdinand Porsche and Auto Union in Hitler's plans for German auto racing. With his experience from racing up maintain passes in the Alps in the 1920s, he was virtually unbeatable when he got the new Auto Union car, which was designed by Porsche. Its rear mounted engine provided superior traction compared to conventional front engine designs, so that its (eventually) 500+ horse-power could be transformed into speed even on non-paved roads.
In circuit racing, the new car was very hard to master, though, due to the swing axle rear suspension design initially adopted by Porsche (relatively advanced for its day, it is now utterly obsolete because of its many problems). His career with Auto Union was quite successful. In 1934, he won the German, Swiss and Czech Grand Prix races (as well as finishing second in the Italian and Eifel Grands Prix).
There was no European Championship for the circuit races that year, or he would have won it. Wins in a number of hill-climb races brought him European Mountain Champion, the first of three he would eventually collect. In 1935, he won the Italian Grand Prix (along with second at the German Grand Prix; he also won his usual collection of hill-climb wins, again taking the European Mountain Championship.
1936 was leaner; he placed second in the Tripoli and German Grands Prix, finishing second in the competition for the European Championship. After Stuck missed a number of hill-climbs because of injuries suffered in accidents, that year the European Mountain Championship fell to his famous team-mate, Bernd Rosemeyer. 1937 was equally lean, bringing only second places in the Rio de Janiero and Belgian Grands Prix.
1938 opened poorly; Stuck was either fired from, or quit, the Auto Union team (accounts from the two sides differ). After a series of injuries to other team drivers, as well as pressure from the German government (again, accounts differ as to what combination of factors was the cause), he was re-hired, and proved himself by winning a third European Mountain Championship, his last major pre-war success.
After the war, although Germans were banned from racing until 1950, Stuck obtained Austrian citizenship and immediately continued racing. A link with Alex von Falkenhausen led to Stuck driving for his team in Formula Two racing, although with little success. He drove a Porsche Spyder in 1953, also with no success. A liaison with BMW, starting in 1957, was more fruitful, although his first hill-climbs for them (in a Type 507) were not. A switch to their tiny Sports Coupé did the trick, and at age 60, he became German Hillclimb Champion for the last time. He decided to retire on a high note, and thereupon closed his professional driving career. As an instructor on the Nürburgring, he taught his son Hans Joachim the secrets of this challenging circuit.
