Born Samuel Wilder in Sucha Beskidzka, Austria-Hungary (now Poland) to Max Wilder and Eugenia Dittler, Wilder was nicknamed Billie by his mother (he changed that to "Billy" after arriving in America). His parents had a successful and well-known cake shop in Sucha Beskidzka's train station and unsuccessfuly tried to convince their son to inherit the business. Soon the family moved to Vienna, where Wilder attended school. After dropping out of the University of Vienna, Wilder became a journalist. To advance his career Wilder decided to move to Berlin, Germany.

While in Berlin, before achieving success as a writer, Wilder allegedly worked as a taxi dancer. After writing crime and sports stories as a stringer for local newspapers, he was eventually offered a regular job at a Berlin tabloid. Developing an interest in film, he began working as a screenwriter. He collaborated with several other tyros (with Fred Zinnemann and Robert Siodmak, on the 1929 feature, People on Sunday). After the rise of Adolf Hitler, Wilder, who was Jewish, left for Paris and then the United States. His mother, grandmother and stepfather were murdered at the Auschwitz concentration camp.
