HARVARD UNIVERSITY’S EMBATTLED PRESIDENT, Lawrence H. Summers,
resigned this afternoon and will be replaced, on an interim
basis, by Derek C. Bok, who was president of Harvard from 1970
to 1990. Mr. Bok would be expected to “clean up the mess and
make conditions right for the next president,” according to a
senior professor with knowledge of the tumultuous events of
today in Cambridge, Mass.
