Hans Einstein
Einstein was born in Berlin, the son of Josefa Spiero Einstein Warburg and Dr. Fritz Einstein. He spent his childhood in Hamburg, Germany as Nazism gradually took hold. His parents were Quakers, but of Jewish origin. A year after Hitler took power in 1934, his mother moved Einstein and his sister to the Netherlands, leaving his father behind. He finished high school at Eerde, a boarding school in the Netherlands at age 16 and moved to the United States as an exchange student. He attended Furman University in Greenville, South Carolina. One of the first things he did upon arriving was look up his last name in the phone book. The only Einstein he found was a relative: Albert Einstein's son, Hans Albert Einstein. They became friends and he was often invited over whenever Albert visited. He earned his medical degree from New York Medical College in 1946 and did his internship at Paterson General Hospital in Paterson, New Jersey. Following that, he became a medical officer in the United States Army. He then completed residencies in Internal Medicine and Pulmonary Diseases at the New York Veterans Hospitals.
Albert Einstein
Except for one year in Prague, Einstein lived in Switzerland between 1895 and 1914, during which time he renounced his German citizenship in 1896, then received his academic diploma from the Swiss federal polytechnic school (later the Eidgenössische Technische Hochschule, ETH) in Zürich in 1900. After being stateless for more than five years, he 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.
