Bernhard Caesar Einstein
Bernard first met his grandfather Albert when he was two years old. As a boy he travelled alone to spend time with Albert in New Jersey, and at Saranac Lake in upstate New York. Einstein recounted to his son Thomas that he used to irritate his grandfather because he would urinate out the window directly above Albert's study in Princeton. At Saranac Lake he enjoyed sailing with his grandfather. Apparently Albert Einstein's favorite time to sail was when there was very little wind. According to Bernard, his grandfather enjoyed the challenge of harnessing whatever little bit of breeze he could capture. The sailing tradition was carried on by Albert's son, Hans Albert, and Bernard's children on the San Francisco Bay. Albert Einstein died in April 1955. Having shared his love of music with his grandson, he bequeathed Bernard his violin in addition to a modest sum of money.
In 1954, Bernard married Doris Aude Ascher (born c. 1938), with whom he had five children:
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.
