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.
Political views of Albert Einstein
Albert Einstein was widely known during his lifetime for his work with the theory of relativity and physics in general. He was also an important peace activist, a world federalist and a socialist. His political opinions were of public interest through the middle of the 20th century due to his fame and involvement in political, humanitarian and academic projects around the world. He was often called upon to give judgments and opinions on matters often unrelated to theoretical physics or mathematics. Einstein's visible position in society allowed him to speak and write frankly, even provocatively, at a time when many people were silenced due to the rise of the Nazi movement.
