In July 1914, Albert Einstein wrote to his first wife, Mileva Maric, the mother of his two sons, laying down a series of conditions under which he would agree to continue their marriage:
''A. You will see to it (1) that my clothes and linen are kept in order, (2) that I am served three regular meals a day in my room. B. You will renounce all personal relations with me, except when these are required to keep up social appearances.'' And: ''You will expect no affection from me . . . You must leave my bedroom or study at once without protesting when I ask you to.''
