"Work on" Haskell already started in the late 80s, too. But it really depends on which date you compare (first protoype? first language spec? first public release? first stable release?) But even so, first public releases were just over a month apart, it's actually closer than I thought.

Ahem. Actually, Haskell is older than Python (although not by much).
