Pulver began her career, after leaving trade school, as a model, and then studied acting. She made her film debut in 1949, in the American comedy Swiss Tour (starring Cornel Wilde). The buxom Pulver want on to become a frequent presence in German and French films, including The Confessions of Felix Krull and The Adventures of Arsene Lupin.
