Pierre de Fermat

The final proof of Fermat’s last theorem was published in 1995 in the journal Annals of Mathematics.12
While Pierre de Fermat famously claimed in 1637 to have discovered a "truly remarkable proof" that could not fit in the margin of his book, he never provided one, leading many to suspect he was mistaken. The successful proof was developed by the British mathematician Andrew Wiles. Although Wiles initially announced his findings in 1993, a gap in the argument was identified, which he subsequently resolved with the assistance of Richard Taylor. The completed work appeared in the paper "Modular Elliptic Curves and Fermat’s Last Theorem" in 1995.12
