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.
Sergey Konenkov
In 1935 he was commissioned by the Princeton University to do a sculpture of Albert Einstein. It is said that Einstein was interested in the work of the Russian sculptor, but was more focused on his wife, Margarita Konenkova. Einstein and Margarita, who also was acquainted with the physicist Robert Oppenheimer, allegedly had a love affair, judging by the "nine of the great scientist's apparently genuine love letters, written in 1945 and 1946." There have been allegations that Margarita was working in those years for the Soviet Government, but no concrete evidence has been provided to support the theory.
