Karl-Günther Bechem (born December 21 1921 in Hagen, Weimar Republic (modern-day Germany)) was a German Formula One racing driver who competed in two German Grands Prix in 1952 and 1953 as a privateer. Bechem entered the first of these under the pseudonym, "Bernhard Nacke" in order to hide his racing career from his family. Bechem failed to finish in both of these races, completing only seven laps (159.67km) of the Nürburgring Nordschleife. Bechem died on May 3 2011.
