Hans Einstein
Einstein was born in Berlin, the son of Josefa Spiero Einstein Warburg and Dr. Fritz Einstein. He spent his childhood in Hamburg, Germany as Nazism gradually took hold. His parents were Quakers, but of Jewish origin. A year after Hitler took power in 1934, his mother moved Einstein and his sister to the Netherlands, leaving his father behind. He finished high school at Eerde, a boarding school in the Netherlands at age 16 and moved to the United States as an exchange student. He attended Furman University in Greenville, South Carolina. One of the first things he did upon arriving was look up his last name in the phone book. The only Einstein he found was a relative: Albert Einstein's son, Hans Albert Einstein. They became friends and he was often invited over whenever Albert visited. He earned his medical degree from New York Medical College in 1946 and did his internship at Paterson General Hospital in Paterson, New Jersey. Following that, he became a medical officer in the United States Army. He then completed residencies in Internal Medicine and Pulmonary Diseases at the New York Veterans Hospitals.
Albert Einstein Archives
Einstein did not save all of his written material, but from 1919, as his fame increased, he employed his stepdaughter Ilse as a secretarial assistant. Helen Dukas (1896–1982) began working for Einstein with increased systematization from April 1928, although not all outgoing correspondence was saved. After the Nazis' rise to power in 1933, Einstein's son-in-law Rudolf Kayser, aided by the French Embassy, rescued Einstein's papers in Berlin. Some of the material at Einstein's summer house in Caputh, Brandenburg was destroyed to avoid seizure, although most of his works between 1930 and 1932 were saved. That material was transported via Haberlandstrasse where Einstein lived in Berlin, then to Paris, and ended up stored in Princeton, New Jersey, United States until after Einstein's death.
