Einstein enjoyed flirting with female admirers,
and a few times he had more passionate affairs. Elsa, despite bouts
of jealousy and loneliness, guided him through his daily routines
like a mother caring for a thoughtless child. After Elsa's death
in 1936, her daughter Margot (right) joined Einstein's secretary
in the task of protecting Einstein from intrusions and helping him
cope with everyday life.
