Hans Albert Einstein 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. Einstein's father, Albert, left Germany in 1933 to escape the virulently antisemitic Nazi threat. Heeding his father's advice, Einstein emigrated from Switzerland to Greenville, South Carolina, in 1938. He worked for the US Department of Agriculture, studying sediment transport from 1938 to 1943. He continued working for the USDA at the California Institute of Technology starting in 1943. In 1947 he
Hans Albert Einstein recognition for more than twenty years of devoted and distinguished service to Applied Mechanics Reviews by the American Society of Mechanical Engineers (1972). In 1927 Hans Albert Einstein married Frieda Knecht. Albert disapproved of Frieda much as his parents had of Mileva. Einstein and Frieda had four children: Frieda died in 1958, and Hans Albert later married neurochemist Elizabeth Roboz (1904–1995).
