Stephanie Glaser was born in Neuchâtel and grew up in Bern. She studied acting at the Reinhardt-Seminar in Vienna and then performed at various theatres in Switzerland and Germany. She was a member of the Bäretatze, Floigefänger and Fédéral comedy troupes, and became, alongside Walter Roderer, one of Switzerland's noted popular actresses as well as a leading figure of the 1950s Swiss comedy scene.
She became known to the general public for her roles in the Gotthelf film adaptations Uli der Knecht and Ueli, der Pächter, and notably for starring as "Aunt Elise" in the TV show Teleboy by Kurt Felix between 1974 and 1981. Later she was also cast in the TV series Motel and Die Direktorin.
In the 1980s she returned to film work and in 2006, at the age of 86, she was cast in her first title role in the critically and commercially successful movie Late Bloomers (Die Herbstzeitlosen). Stephanie Glaser continued working as an actress in her old age. A few months before she died on 14 January 2011, aged 90, she had been shooting scenes for the TV movie Mord hinterm Vorhang.
