Albert Einstein acquired Swiss citizenship in 1901, which he kept for the rest of his life. In 1905, he was awarded a PhD by the University of Zurich. The same year, he published four groundbreaking papers during his renowned "annus mirabilis" (miracle year) which brought him to the notice of the academic world at the age of 26. Einstein taught theoretical physics at Zurich between 1912 and 1914 before he left for Berlin, where he was elected to the Prussian Academy of Sciences.

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
