Answer 1

In 1914, Einstein set down rules for his first wife if she expected to stay with him in a private letter.

As far as can be gathered, Jeremy Norman bought the letter in November 26, 1996 in an auction.

Answer 2

ALBERT EINSTEIN'S most famous letter was arguably the most influential and fateful of modern times: the Nobel laureate's 1939 warning to President Franklin D. Roosevelt of the n***s' nuclear potential, which led to the Manhattan Project and the development of the atom bomb.

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, (3) that my bedroom and study are always kept in good order and that my desk is not touched by anyone other than me. B. You will renounce all personal relations with me, except when these are required to keep up social appearances. In particular you will not request (1) that I sit with you at home, (2) that I go out with you or travel with you. C. You will promise explicitly to observe the following points in any contact with me: (1) you will expect no affection from me and you will not reproach me for this, (2) you must answer me at once when I speak to you, (3) you must leave my bedroom or study at once without protesting when I ask you to go. D. You will promise not to denigrate me in the eyes of the children, either by word or deed.
