After World War I, he became a professional skater and he was Professional World Champion in 1920. He continued his skating career until 1929. In that last year of his career, then 40 years old, he went to Davos, where people were preparing for the European Championships, and proved that he could still skate fast by beating the world record times on both the 500 m and the 1,000 m, although his times were not recognised as world records because he was a professional skater.
