Gustav Frands Wilzeck Winckler (13 October 1925 – 20 January 1979) was a popular Danish singer, composer and music publisher. He grew up in the Nørrebro district of Copenhagen and started his career as a decorator.
In 1948 as a young man he won a talent competition at National Scala Theatre in Copenhagen, as well as many others in Copenhagen. He was often compared to Bing Crosby.
He finally broke through in 1950 with engagements, regular appearances on Danmarks Radio and his first professional recording. Through the 1950s he recorded and toured in Denmark, Germany (under the name Gunnar Winkler) and England (under the name Sam Payne).
In 1957 after qualifying in the Dansk Melodi Grand Prix to represent Denmark at the Eurovision Song Contest, he participated in Eurovision Song Contest 1957, where he sang "Skibet skal sejle i nat" ("The ship is leaving tonight") with Birthe Wilke. They ranked number 3, and stunned television audiences with a 13-second-long kiss at the end of their performance.
Gustav Winckler (22 April 1897 – 19 December 1980) was a German jurist. The son of a Lutheran minister, he became a member of the Nazi Party, but in the early 1930s, pursued claims of torture and abuse at Kemna concentration camp, which brought threats against his life. After World War II, he was contacted by people trying to bring the case to trial and he joined their efforts, which in 1948, resulted in a number of convictions.
