 Fermat s Last Tango was inspired by the achievements of Princeton University Mathematics Professor Andrew Wiles, who in June 1993 presented a proof to the theorem first set forth by French mathematician Pierre de Fermat in 1637. "Fermat s Last Tango" is a musical fantasia based on the true encounter between mathematician Andrew Wiles and Fermat s last theorem. The music composed by Joshua Rosenblum, the book by his wife Joanne Lessner, and the clever lyrics by the pair provide extraordinary entertainment. The play makes a clear statement about the enduring importance of mathematics and its intellectual impact over the millennia.
