Wikipedia records that "after 358 years of effort by mathematicians, the first successful proof was released in 1994 by Andrew Wiles and formally published in 1995." Browsing by proved year shows how long a stated theorem can wait before a genuine proof arrives.Facts20th centurySourcesComments (0)Reader Challenges (0)FactsComparisonEra Of EmergenceWell-attested1950 120th centuryFilter Results59 entriesBranchAllCoding Theory (1)Combinatorics (15)Geometry (1)Graph Theory (29)Linear Algebra (1)Logic and Foundations (1)Set Theory (1)Proved ByAllEndre Szemeredi (4)George Polya (1)Klaus Wagner (2)Nicolaas Govert de Bruijn (1)Pal Turan (1)Paul Erdos (5)Ronald Fisher (1)W.
