Serota’s been a vibrant presence as the director of the Tate Modern since 1988. He’s not only navigated the museum through a tightening of government funding, but also myriad financial crises in the private sector. His interest and commitment to more contemporary art has led Tate into more progressive works, including the Tanks, a facility dedicated entirely to performance art and works of film. He’s not only forward thinking, he’s pragmatic and prescient—and a name you should know.
