Enrico Giusti (28 October 1940 – 26 March 2024) was an Italian mathematician mainly known for his contributions to the fields of calculus of variations, regularity theory of partial differential equations, minimal surfaces and history of mathematics.

[2] After retirement, he devoted himself to the managing of the "Giardino di Archimede",[3] a museum entirely dedicated to mathematics and its applications.

[4][5] One of Giusti's most famous results, obtained with Enrico Bombieri and Ennio De Giorgi, concerned the minimality of Simons' cones, and made it possible to disprove the validity of Bernstein's theorem in dimensions larger than 8.

The work on minimal surfaces was mentioned in the citation of the Fields Medal eventually awarded to Bombieri in 1974.

At the time of his death, he was the director of the Garden of Archimedes, a museum devoted to mathematics in Florence, Italy.
