Hans Albert Einstein

Hans Albert Einstein (May 14, 1904 – July 26, 1973) was a Swiss-American engineer and educator, and the second child and first son of Albert Einstein and Mileva Marić. Hans A. Einstein was a life-long professor of Hydraulic Engineering at the University of California, Berkeley, and was best known for his research on sediment transport. Hans Albert Einstein's papers are held at the Water Resources Collections and Archives in the University of California, Riverside Libraries and in the University of Iowa Libraries Special Collections and Archives.

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. 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.

Einstein followed his father's footsteps and studied at ETH, the Swiss Federal Institute of Technology, in Zurich, Switzerland. In 1926 he was awarded a diploma in civil engineering. From 1926 to 1930 he worked as a steel designer on a bridge project in Dortmund. In 1936 Hans Albert obtained the doctor of technical science degree. His doctoral thesis "Bed Load Transport as a Probability Problem" is considered the definitive work on sediment transport.
