Hans Albert Einstein
Hans Albert Einstein was born on May 14, 1904 in Bern, Switzerland, where his father, Albert Einstein, worked as a clerk in the patent office. His father was of German-Jewish descent and his mother, Mileva Marić, Serbian-Orthodox. His younger brother, Eduard Einstein, was born in 1910 and died in 1965. The fate of his older sister, Lieserl Einstein, Albert Einstein's and Mileva Marić's first child, is unknown. Their parents divorced in 1919 after living apart for five years.
Zoellner Quartet
More than a dozen years later, in January 1931, Albert Einstein, who was then engaged in research at the California Institute of Technology, visited the Zoellner family's conservatory and played violin with members of the quartet in music of Beethoven and Mozart. The following year, a few days before Einstein sailed for what would be his last visit to Germany, he presented Joseph Zoellner with an autographed photograph as a memento of the occasion.
