How old would Yves Bonnefoy be today?

Yves Jean Bonnefoy was a French poet and art historian. He also published a number of translations, most notably the plays of William Shakespeare which are considered among the best in French. He was a professor at the Collège de France from 1981 to 1993 and is the author of several works on art, art history, and artists including Miró and Giacometti, and a monograph on Paris-based Iranian artist Farhad Ostovani.
