File: LeonhardEuler !!! Sorry? Who? [[[> http://plus.maths.org/issue42/features/wilson/Euler.jpg ]]] LeonhardEuler (pronounced "Oiler") (1707-1783) was a Swiss mathematician who made contributions to fields as diverse as calculus, topology, mechanics, optics and astronomy. He is also credited with inventing GraphTheory. He was involved in work to solve the greatest problem of the age - the Longitude problem - and is regarded by some as the most prolific mathematician ever to have lived. Others dispute that, pointing instead at PaulErdos, but while Erdos published more papers, Euler published more pages. Pierre-Simon Laplace said: "Read Euler, read Euler, he is a master for us all." ---- !!!

Footnote Euler is also a Ph.D. supervisor ancestor of ColinWright, something of which Colin is simultaneously proud, and embarrassed, which is an interesting trick.
