The Daescher technique superseded the Kongsberger technique developed by Jacob Tullin Thams and Sigmund Ruud (both from Norway) after World War I in Kongsberg.
Erich Windisch, a German Olympic ski jumper, who developed in 1949 a jumping technique in which the jumper's arms are slightly arched and pointing downward, is also credited along with Däscher of developing the revamped aerodynamic jumping style that was used in elite competition for over 30 years.
On 3 March 1950, he set the ski jumping world record distance for a very short period of time at 130 metres (426.5 ft) on Heini-Klopfer-Skiflugschanze in Oberstdorf, West Germany.
His brother, Hans Däscher, was also a ski jumper.
Andreas Däscher died in Meilen on 4 August 2023, at the age of 96.
