I am currently reading a book (Israel by daniel gordis) about the history of the nation of Israel from the late 1800s to the present and it goes in depth about the various professions and careers that were common for Jewish people in Europe prior to the holocaust. But it got me wondering how there came to be such a large presence of Jewish people in the American entertainment industry and Hollywood?

It’s my understanding that the motion picture industry as we know it today primarily started in the 1930s and 40s. What drew a lot of Jewish people to this industry or how did they get so involved at such a high rate?
