Hans Albert Einstein
Hans Albert Einstein was born on May 14, 1904 in Bern, Switzerland, where his father, Albert Einstein, worked as a clerk in the patent office. His father was of German-Jewish descent and his mother, Mileva Marić, Serbian-Orthodox. His younger brother, Eduard Einstein, was born in 1910 and died in 1965. The fate of his older sister, Lieserl Einstein, Albert Einstein's and Mileva Marić's first child, is unknown. Their parents divorced in 1919 after living apart for five years.
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.
