Einstein and Meliva had an illegitimate daughter Meliva named "Lieserl". Einstein wrote in a letter that "I love her so much and don't even know her yet!" and begs for a photograph or a drawn picture; without meeting his girl, he dotes and worries over Lieserl's welfare. Doubly heartwarming that Einstein had wanted and expected a son in the first place. A Downer Ending that it was indicated that Einstein never met his daughter. She may have died of scarlet fever or was given up for adoption.
