Pierre de Fermat
Fermat, portrait by Roland Lefèvre; in the Narbonne City Museums, France
After Andrew Wiles presented his initial proof of Fermat’s last theorem in 1993, a gap was discovered in the argument. Wiles successfully repaired the proof with the assistance of his former student, Richard Taylor. The completed work was published in 1995, including a coauthored article titled "Ring-Theoretic Properties of Certain Hecke Algebras".12
