Albert Ein­stein pas­sion­ate­ly wooed his first wife Mil­e­va Mar­ic, against his family’s wish­es, and the two had a tur­bu­lent but intel­lec­tu­al­ly rich rela­tion­ship that they record­ed for pos­ter­i­ty in their let­ters. Ein­stein and Maric’s love let­ters have inspired the short film above, My Lit­tle Witch (in Ser­bian, I believe, with Eng­lish sub­ti­tles) and sev­er­al crit­i­cal re-eval­u­a­tions of Einstein’s life and Mar­ic’s influ­ence on his ear­ly thought. Some his­to­ri­ans have even sug­gest­ed that Maric—who was also trained in physics—made con­tri­bu­tions to Einstein’s ear­ly work, a claim hot­ly dis­put­ed and, it seems, poor­ly sub­stan­ti­at­ed.

The letters—written between 1897 and 1903 and only dis­cov­ered in 1987—reveal a wealth of pre­vi­ous­ly unknown detail about Mar­ic and the mar­riage. While the con­tro­ver­sy over Mar­ic’s influ­ence on Ein­stein’s the­o­ries raged among aca­d­e­mics and view­ers of PBS’s con­tro­ver­sial doc­u­men­tary, Einstein’s Wife, a scan­dalous per­son­al item in the let­ters got much bet­ter press. As Ein­stein and Maric’s rela­tion­ship dete­ri­o­rat­ed, and they attempt­ed to scotch tape it togeth­er for the sake of their chil­dren, the avun­cu­lar paci­fist wrote a chill­ing list of “con­di­tions,” in out­line form, that his wife must accept upon his return.
