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:
Albert Einstein
An early correspondence between Einstein and Marić was discovered and published in 1987 which revealed that the couple had a daughter named "Lieserl", born in early 1902 in Novi Sad where Marić was staying with her parents. Marić returned to Switzerland without the child, whose real name and fate are unknown. The contents of Einstein's letter in September 1903 suggest that the girl was either given up for adoption or died of scarlet fever in infancy.
Einstein and Marić married in January 1903. In May 1904, their son Hans Albert Einstein was born in Bern, Switzerland. Their son Eduard was born in Zürich in July 1910. The couple moved to Berlin in April 1914, but Marić returned to Zürich with their sons after learning that Einstein's chief romantic attraction was his first and second cousin Elsa. They divorced on 14 February 1919, having lived apart for five years. Eduard had a breakdown at about age 20 and was diagnosed with schizophrenia. His mother cared for him and he was also committed to asylums for several periods, finally being committed permanently after her death.
