In the summer of 1976, the University of Illinois had the audacity to use their postage meter to print the words "Four Colors Suffice" on the outgoing mail. The words referred to the recently announced computer-aided proof of the very famous Four-Color Conjecture by Kenneth Appel and Wolfgang Haken (with a significant contribution by John Koch) at the Urbana campus. Their announcement was originally greeted with a rather large degree of skepticism by the mathematical community. This skepticism was not without cause. For about a century there have been numerous rumors and claims of proofs or counterexamples to the conjecture. In fact, in 1971 a different computer-aided "proof" by Shimomoto was announced but later withdrawn after it failed to survive close scrutiny. Furthermore Hakin's name had somehow been associated (perhaps unfairly) with this ill-fated work
