The family life of one of the greatest scientists was far from being happy. He married Mileva Maric in 1903 and divorced her in 1919. In the intial phase of married life, Einstein was happy but after sometimes quarrels began and they splitted though the couple has three children.
In a letter to her, found recently, Einstein accuses her of not passing his letters to his children. He arrived at this conclusion from the fact that children did not return him any greetings as they were unaware of his letters.
There were also quarrels over the money he sent for the maintenance. He wrote that every quarter he sent 5600 marks which drained his income.
This letter is written in his own handwriting on 12th December 1914 and is going under hammer soon
