    As the note at the bottom of the page mentions, the 'tree' part of that can be got for any mathematician from the wonderful Mathematics Genealogy Project: http://genealogy.math.ndsu.nodak.edu/index.php http://genealogy.math.ndsu.nodak.edu/index.php. While we're on collaborations and curiosities, I could have sworn that there was a page out there that would try to calculate your Erdös number automatically (maybe through MathSciNet?), but I can't seem to find it.
