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.
Bernhard Caesar Einstein
Bernard Einstein was the son of Hans Albert Einstein and Frieda Einstein (née Knecht), who had married in 1927 in Switzerland. He was born on 10 July 1930 in Dortmund, Germany, where Hans Albert was involved in a bridge building project. Hans Albert was the only one of Albert Einstein's three children to marry and have children. Hans Albert's sister, Lieserl Einstein, is assumed to have died in infancy, although it has been suggested that she was given up for adoption. Hans Albert's younger brother Eduard Einstein developed severe schizophrenia in early adulthood and died at age 55, and had no children. Bernard's brother Klaus was born in 1933 and died at age 6 of diphtheria in Clemson, South Carolina. Frieda also had David, who died in early infancy. Eventually, Hans Albert and Frieda adopted a girl, Evelyn, shortly after she was born in 1941. Frieda died in 1958; and one year later Hans Albert married Elizabeth Roboz, a neurochemist.
