Margot Einstein at the home of Freeman Dyson

At the home of Freeman Dyson, Albert Einstein's stepdaughter, Margot, is seated in the blue chair, while two of the Dyson children, Esther and Dorothy, are seated on the floor. Freeman Dyson's wife, Imme, appears to be the person barely visible at the top right of the photograph. Freeman Dyson was then a Professor on the faculty of the Institute for Advanced Study's School of Mathematics.
