What was Albert Einstein's ethnicity?

Albert Einstein was born in Germany on March 14, 1879. After winning the 1921 Nobel Prize in Physics for discovering the law of the photo electric effect, he escaped from Nazi Germany in 1933 and alerted the U.S. that Germany might be developing an atomic bomb. He then helped research the atomic bomb along with other scientists of the time. Although America accepted him as a citizen, as he legally became after some time in the states, Einstein's origin lies in Germany.
