At the 1948 Winter Olympics, Beiser won the gold medal in the combined and the silver medal in the downhill competition. In 1952 she became Olympic downhill champion. Between these two Olympics, Beiser won two medals at the 1950 World Championships in Aspen, Colorado; a gold in the downhill and a silver in the giant slalom. She did marry Alfred Jochum after the 1948 Olympics. Four months earlier (in regard to the World Championships), she had given birth to her first child. After her racing career, Beiser worked as skiing trainer and opened a café (named "Café Olympia") in her home town.
