Marguerite Maria Vogt was born in Berlin, Germany, in 1913, the second of two daughters to Oskar Vogt and Cécile Vogt-Mugnier.
Her parents were neurologists at the Kaiser Wilhelm/Max Planck Institute for Brain Research in Berlin. Her father, Oskar,
also a neuroanatomist, was summoned to Moscow to examine Lenin's brain in 1925. Both daughters were directed by their parents
into science at an early age. In the early 1930s, Marguerite's older sister, Marthe, was a neuropharmacologist, with a MD
from University of Berlin and an additional doctorate in chemistry. In the 1930s with the rise of the Third Reich, Marthe
eventually relocated to Britain to work at the National Institute for Medical Research.
