Gerhard Frey
Quick Summary
Gerhard Frey is a German mathematician known for his work connecting Fermat's Last Theorem to conjectures about elliptic curves. In 1980, Frey proposed that if Fermat's Last Theorem were false, the resulting equation would define a curve with properties that contradicted the Taniyama-Shimura conjectures. This observation, refined by Jean-Pierre Serre and proven by Ken Ribet, demonstrated that proving the Taniyama-Shimura conjectures would, in turn, prove Fermat's Last Theorem. Andrew Wiles later established these conjectures, solving Fermat's Last Theorem.1
