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.

Albert Einstein ATV was opened on 18 June. The hatch opening was delayed by a day due to concerns raised by Roscosmos that the cargo had not been disinfected satisfactorily. On 19 June 2013, "Albert Einstein" conducted its first reboost of the ISS, performing a 407-second burn which provided a delta-v change of 1.0 m/s to the station. A further reboost was undertaken on 10 July 2013, where a burn of just less than 10 minutes provided a delta-v change of 1.45 m/s; this operation consumed of propellant. By 12 July 2013, all the dry cargo had been unloaded from "Albert Einstein", allowing
