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:
Mileva Marić
The marriage had been strained since 1912, in the spring of which Einstein became reacquainted with his cousin, Elsa. They began a regular correspondence. Marić, who had never wanted to go to Berlin, became increasingly unhappy in the city. Soon after settling in Berlin, Einstein insisted on harsh terms if she were to remain with him. In 1914, she took the boys back to Zürich, a separation that was to become permanent. Einstein made a legal commitment to send her an annual maintenance of 5600 Reichsmarks in quarterly instalments, just under half of his salary. After the required five years of separation, the couple divorced on February 14, 1919.
