Lawrence H. Summers resigned after a brief and turbulent tenure, nudged by Harvard's governing corporation, and facing a vote of no confidence from the influential Faculty of Arts and Sciences. The announcement raised questions about future leaders' ability to govern Harvard with its vocal and independent-minded faculty. Summers, who earns a base salary of $579,000 is to leave office June 30. Derek Bok, 75, who was Harvard's president from 1971 to 1991, will serve as interim president. Summers will be forever remembered for his statement last year that women might lack an intrinsic aptitude for math and science.
