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
Political views of Albert Einstein to eliminate Einstein's work from the German lexicon as unacceptable "Jewish physics" ("Jüdische Physik"). Instructors who taught his theories were blacklisted, including Nobel laureate Werner Heisenberg, who had debated quantum probability with Bohr and Einstein. Philipp Lenard claimed that the mass–energy equivalence formula needed to be credited to Friedrich Hasenöhrl to make it an Aryan creation. A man convicted of inciting others to kill Einstein was fined a mere six dollars. After World War II ended, and the Nazis were removed from power, Einstein refused to associate with Germany. Einstein refused several honors bestowed upon him by Germany, as he
