One more biography of Einstein

I guess the 100th anniversary 2 years ago of the `Annus Mirabilis' has again set off interest in the life and work of Einstein. There is yet another biography which has been reviewed here. Last year I went to a wonderful exhibition on his life at the Historical Museum in Bern. I am proud that I have atleast one link with Einstein, having worked in Bern for a year in the same department where he had been.
