How did Ernst Lubitsch become popular as a comic actor in Germany?

Ernst Lubitsch achieved popularity as a comic actor in Germany by performing in one-reel silent film comedies shortly before World War I.1

He gained recognition through his portrayal of Meyer, a character depicted as a well-meaning but bungling Jewish man. While this role relied on ethnic stereotypes common to the era, it was presented in a sympathetic manner that resonated with audiences. His success in these performances eventually led him to take on the roles of writer and director for the Meyer film series, marking the beginning of his transition into full-time filmmaking.1
