Albert Warner
Aaron Albert Warner was a Polishborn Jewish and American film executive who was one of the founders of Warner Bros. Studios. He established the production studio with his brothers Harry, Sam, and Jack L. Warner. He served as the studios treasurer, until he sold his stock in 1956.
Abraham Wonsal or Wonskolaser, later Abraham Warner, was born in Congress Poland, and in the village Krasnosielc, He was the son of Benjamin Wonsal or Wonskolaser, a shoe maker born in Krasnosielc, and Pearl Leah Eichelbaum. He came to Baltimore, Maryland with his mother and siblings in October 1889 on the steamship Hermann from Bremen, Germany. Their father had preceded them, immigrating to Baltimore in 1888 and following his trade in shoes and shoe repair. He changed the family name to Warner, which was used thereafter. As in many Jewish immigrant families, some of the children gradually acquired anglicized versions of their Yiddishsounding names. Abraham and Jacob were late among the children to do so, becoming Albert and Jack after they came of age. However, his nickname was Abe.
