Thomas Martin Einstein

The Einstein family is the family of physicist Albert Einstein (1879–1955). Einstein's fourth-great-grandfather, Jakob Weil, was his oldest recorded relative, born in the late 17th century, and the family continues to this day. Albert Einstein's second-great-grandfather, Löb Moses Sontheimer (1745–1831), was also the grandfather of the tenor Heinrich Sontheim (1820–1912) of Stuttgart.
