A postcard from Albert to his second wife Elsa.

Albert Einstein's step-daughter Margot had stipulated in an agreement with the Hebrew University of Jerusalem dating from 1984 that letters in her possession, inherited from her step-father after his death in 1955 would be given to the Hebrew University but should be kept sealed and away from the public's eye for 20 years after her death. By the beginning of 1986 the material had arrived in Jerusalem. Margot had passed away a short time later, in July 1986. By July 8th, 2006 the 20-year period since her death had lapsed. Now the time had come to make the letters available to the public.

Since then, all of the material, spanning from 1914 to 1955, is available at the Albert Einstein Archives in Jerusalem for the interested public.

Part of this material, covering the period up to the end of 1920 has already been published by the Collected Papers of Albert Einstein project in its volume number 10, covering the period May to December 1920. Further letters will be published in the volumes to come.

The following text was released by the Hebrew University on the day of the first presentation of the newly released material:

A large collection of correspondence shedding light on Einstein's personal life and perspectives was made public today by The Albert Einstein Archives at the Hebrew University of Jerusalem.

Spanning almost 3500 pages, the correspondence encompasses letters to and from his first and second wives and children between the years 1912-1955.

This newly released batch of letters fill in details to create a ''higher resolution'' image of Einstein beyond what was previously known of his personal life. The collection has been in the Einstein Archives at the Hebrew University for many years, but was not made public in accordance with the Last Will and Testament of Einstein’s stepdaughter, Margot, who specified that they not be revealed until 20 years after her death. Margot died in July 1986.

Einstein wrote almost daily letters to his second wife Elsa and to her daughter Margot whilst away from home about delivering and listening to boring lectures, playing music with friends, or trying to stop smoking.

However, the most striking aspect of this correspondence is the way in which Einstein openly discusses his extramarital affairs with Elsa and Margot, and his wife's reluctant acceptance of the situation.

On his love affairs:
Despite declaring in one letter that ''I must seek in the stars what was denied to me on earth,'' it appears that while he may have sought in the stars, he did in fact find on earth. In 1923, he fell in love with a friend's young niece who had become his secretary, and he did his utmost to integrate her into his family life.

Between the mid-1920s and his emigration to the U.S., there were other women in Einstein’s personal life: a Margarete, an Estella, a Toni, an additional Toni and an Ethel shared the pleasure of sailing, reading books attending concerts, and more with Einstein.

References are made to women throughout his letters, often with the premise that they were chasing him, showering him with “unwanted” affection. A letter to his wife Elsa reads: ''Mrs. M. definitely acted according to the best Christian-Jewish ethics: 1) one should do what one enjoys and what won't harm anyone else; and 2) one should refrain from doing things one does not take delight in and which annoy another person. Because of 1) she came with me, and because of 2) she didn't tell you a word. Isn't that irreproachable?''

In a letter to his stepdaughter, Margot, in 1931, Einstein confides in her, ''It is true that Mrs. M. followed me [to England] and her chasing after me is getting out of control…''

After Elsa's death, messages Einstein wanted to be delivered to a certain Margarita – today known as Einstein's Russian spy lover – were passed through his daughter Margot's hands: ''I'm enclosing a little letter for Margarita, thus avoiding to provide curious eyes with tidbits…'' The letter to Margarita – about whom there have been earlier revelations – is not included in this collection.

The batch of letters also deal with a number of other facts of Einstein's life, including the full story of Einstein's Nobel prize money, his relationship with his son and step-daughter, and his thoughts on relativity.

On his Nobel Prize money:
Despite reports that Einstein transferred the Nobel Prize money directly to Switzerland following a divorce agreement in which it was assigned to his first wife, Mileva, these letters reveal that he instead invested the major part of it in the United States, much of which was later lost in the Depression.

On his son:
Particular attention is dedicated to Einstein's relationship with his son, Eduard. Einstein found his son's schizophrenia difficult to accept, and on more than one occasion expresses the idea that it would have been better had Eduard not been born.

On his step-daughter:
In a letter to Elsa in 1924, Einstein tells her, ''I love her [Margot] as much as if she were my own daughter, perhaps even more so, since who knows what kind of brat she would have become [had I fathered her].''

On relativity:
In a letter to Elsa in 1921, he admits, ''Soon I'll be fed up with the relativity. Even such a thing fades away when one is too involved with it…''
