Hans Olsen

After graduating in 1902, Hans Olsen had his dental examination in December 1906. He completed his three-years assistantship from 1907-09. In 1910 he had a study stay at the University of California Dental College in San Francisco and attended post graduate courses in Chicago. One year later, he started practicing in København (Copenhagen). In 1918, he changed his surname from Olsen to Frender. He married Hedevig Benedicte Burchardt, a nurse in 1921. Olsen-Frender retired in 1949.

At the 1912 Olympic Games in Stockholm Olsen competed in the foil and épée individual and the épée and sabre team events. Twelve years later, he was entered in all three team events but did not start. Instead, he acted as jury president in the individual foil event. Olsen never won a national championship title.
