Ditto on the Euclid and Gauss.ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€š The other two, you've got me stumped... but then again, I didn't study much math in College, versus you, my friend....
"Who made me the genius I am today,
The mathematician that others all quote?
Who's the professor that made me that way,
The greatest that ever got chalk on his coat?
One man deserves the credit,
One man deserves the blame,
and Nicolai Ivanovich Lobachevsky is his name. Oy!
Nicolai Ivanovich Lobachevsky is his name."
From "Lobachevsky" by Tom Lehrer (who was also a Math Professor)
