- Solving Hilbert’s nineteenth problem. The result that, more than any other, brought De Giorgi into the élite of the great mathematicians was the solution to one of the 23 challenges that David Hilbert had posed in 1900 to the mathematical community.
- The art of counterexample. One of the specialities of De Giorgi, to disprove results nobody could prove, was his ability to find counterexamples. A significant case concerned precisely the possibility of extending Hilbert’s 19th problem to systems of differential equations, that is, to sets of several equations to be solved simultaneously.
- Geometric measure theory. If De Giorgi was able to solve Hilbert’s 19th problem, it was mainly thanks to the results he had obtained, soon after his graduation, in geometric measure theory, an area undergoing a phase of development in those years.
- Minimal surfaces. After solving Hilbert’s 19th problem and becoming a professor, De Giorgi published nothing for a couple of years. He was absorbed in the problem which he had had at heart since early in his life: the regularity of minimal surfaces such as soap bubbles.
This biography illuminates the life of Ennio De Giorgi, a mathematical genius in parallel with John Nash, the Nobel Prize Winner and protagonist of A Beautiful Mind.

Ennio De Giorgi was a mathematician of ex-ceptional creativity. An original mind, an authen-tic believer in God, and a man with an innate sense of humanity, he enjoyed sharing his thinking on the connections between Mathematics and Wis-dom (in the meaning of the Bible, which he often quoted). A passionate advocate of human rights,
Ennio De Giorgi (February 28, 1928 to October 25, 1996) De Giorgi was an Italian mathematician most famous for solving one of “Hilbert’s problems.” In 1900, the great mathematician David Hilbert published a list of 23 problems that he regarded as the most important unsolved problems in mathematics.

For me the most suggestive indicator is in the Book of Proverbs, one of the most ancient books of the Bible, which at a certain point says that wisdom (which is wider than mathematics) was with God when He created the world and that this wisdom is to be found by men who search for it and adore it.
