In the 1980s, she added to Einstein scholarship by coming up with an unpublished manuscript by her grandfather quoting what were obviously love letters. This led to the discovery in 1986 of 500 of Einstein’s letters in a safe-deposit box in Berkeley. The letters cast new light on his life, particularly his torturous relations with his first wife, Mileva Maric.
One letter detailed Einstein’s instructions to his wife if she wanted to continue their marriage. “You will expect no affection from me,” it read. “You must leave my bedroom or study at once without protesting when I ask you to.”
The letters were auctioned off for $900,000 by an Einstein family trust in 1996, prompting Ms. Einstein to join a suit by a group of family members for a share of the proceeds. The family settled the matter privately.
I guess it depends on the settlement...
