John Baez points to a remarkable mathematician (having being lead there by Alissa Crans):
You may have heard of the Mathematics Genealogy Project. This is a wonderful database that lets you look up the Ph.D. advisor and students of almost any mathematician. This is how I traced back my genealogy to Gauss back in week166.
I was feeling pretty proud of myself, too — until I found someone who had two Ph.D. students before he was even born!
Yes indeed: our friend and café regular Tom Leinster is listed as having two Ph.D. students: Jose Cruz in 1959, and Steven Sample in 1965. At the time he was teaching at the University of Illinois at Urbana-Champaign. Later he took an extended sabbatical, got born in England, and transferred to kindergarten. After a lively second career as a youth, he returned to academia and got his Ph.D. at Cambridge under Martin Hyland in 2000. He now has a permanent position at the University of Glasgow. But who can say what he’ll do next?
Check it out soon, since it may go away.
And yes I posted this just so I could used the words “closed timelike mathematicians.”
