How can you write letters to Nobel Laureates?

I'm studying to become a chemist, and would like maybe a few inspirational words or maybe even an autographed photo from some Nobel winners like Robert Grubbs or Richard Schrock. Anyone know how I could manage to send a letter to one?|||Most of the nobel laureates are professors at different institutes of education so you can find out where they work and contact them. NOTE- some may be grumpy so dont be offended if they dont reply. I have helped you with Robert Grubbs so follow the link-

I am studying chemistry myself and my hero is the late italian chemist Primo Levi
