Because @Decapitated already suggested my first idea (now an answer), "polymath", this answer is about a nearly-synonymous two-word runner-up candidate.
Renaissance [wo]man:
The term Renaissance man or woman or polymath is used for a very clever person who is good at many different things. The idea comes from a time of history called the Renaissance which lasted from about 1400 to about 1600. One of the most famous people alive during this time was Leonardo da Vinci. He was most famous as a painter, but he was also a scientist, engineer and mathematician. Leonardo is called a "Renaissance man".[1] Another "Renaissance man" was Michelangelo, who was a sculptor, painter, architect and poet. (wikipedia.org)
According to Britannica.com, this person is (emphasis added)
also called Universal Man, Italian Uomo Universale, an ideal that developed in Renaissance Italy from the notion expressed by one of its most-accomplished representatives, Leon Battista Alberti (1404–72), that “a man can do all things if he will.”
Here is a use in the wild, a quote from the new yorker about a con artist:
Allen Wolfson was a Renaissance man, in his own way. Between 1999 and 2002, he was involved in the stock-market rise of at least seven companies. Freedom Surf made wet suits and surf apparel. Learner’s World ran a day-care center. Stem Genetics did stem-cell research. Rollerball International made inline skates. Hytk produced and transported natural gas. The only thing connecting these companies was Allen Wolfson—that, and the fact that they were scams.
