Biellmann spin
The spin is named after Swiss skater Denise Biellmann, who popularized the move. Biellmann performed the spin beginning in the 1970s, having learned it from her teammate, fellow Swiss skater Karin Iten. Biellmann performed the spin on her way to becoming World Champion and the spin was officially named for her. It is the only figure skating spin officially named after a skater in International Skating Union regulations.
