Feinstein was born Dianne Emiel Goldman[1] in San Francisco, to Betty (née Rosenburg), a former model, and Leon Goldman, a surgeon. Feinstein's paternal grandparents were Jewish immigrants from Poland. Her maternal grandparents, the Rosenburg family, were from Saint Petersburg, Russia.[9] While they were of German-Jewish ancestry,[10] they practiced the Russian Orthodox faith, as was required for Jews residing in Saint Petersburg.[9][11]
Feinstein graduated from Convent of the Sacred Heart High School, San Francisco in 1951 and from Stanford University in 1955 with a Bachelor of Arts in History.[2]
