Lieserl Einstein

• Birth Notes
  • The pregnancy remained a secret because Einstein and Maric are not married.

• Death Notes
  • Michele Zackheim, in her book on Lieserl, Einstein's daughter, states that Lieserl was mentally challenged at birth, and that she probably died of scarlet fever as an infant.

• General Notes
  • Lieserl, born before their marriage, is variously said to have been given up for adoption or to have died in childhood; her actual fate is unknown.
    
    From letters exchanged by Albert and Mileva, it is thought that Lieserl stayed with Mileva's family for some time before perhaps being given up for adoption.
    
    Lieserl's existence was unknown to biographers until 1986, when a batch of letters between Albert and Mileva was discovered by their granddaughter. Discussion of Lieserl by the couple ended in 1903, and she was never again mentioned in their correspondence.
