Following the Gossip :)

While searching an idea to write in my math blog, I found an interesting web: http://www.genealogy.ams.org/ By entering a mathematician name, you can find out who was his/her supervisor. My searching become interesting with some additional information. Hihi, I shouldn't turn my blog into a gossip column shouldn't I? The hint is by their last name and the information I got from out of the web. It match!!! Bingo.
