Born in Germany to American parents, dark-haired Betty Amann (born Philippine Amann) grew up in the United States. She began her screen career as Bee Amann in the mid-'20s, but returned to Germany after appearing in a Tom Tyler Western for low-budget FBO. Arriving in the wake of Louise Brooks, she was awarded a screen test by Erich Pommer and went on to star or co-star in such German productions as Joe May's silent Asphalt (1929) and the talkies The White Devil (1930), opposite Lil Dagover and Mousjoukine, and Die Kleine Schwindlerin (1933), opposite Dolly Haas. She later did Daughters of Today (1933) in England, but was back in Hollywood by the mid-'30s where she mainly appeared in poverty row productions. Her final appearance came in Edgar G. Ulmer's bizarre Isle of Forgotten Sins (1943) as one of Gale Sondergaard's "hostesses."
