Thomas Martin Einstein
Albert Einstein had three children, Lieserl Maric (1902–1903?), Hans Albert Einstein (1904–1973), and Eduard "Tete" Einstein (1910–1965), but only Hans Albert is known to have married and had children. Hans Albert's only biological child to survive to adulthood was Bernard Caesar Einstein (1930–2008), who was a physicist and the father of Thomas Martin Einstein.
Einstein family
During World War I, Pauline fell ill with cancer. In 1918, when visiting her daughter, Maria, and son-in-law, Paul Winteler, in Luzern, Pauline was taken to the sanatorium Rosenau, due to her illness. At the end of 1919, Albert took his terminally-ill mother out of the sanatorium in Luzern and brought her to Haberlandstrasse 5, Berlin, to stay with him and his second wife, Elsa, where she later died.
