“Management is the capacity to handle multiple problems, neutralize various constituencies, motivate personnel….Leadership, on the other hand, is an essential moral act, not — as in most management — an essentially protective act. It is the assertion of a vision, not simply the exercise of a style.’’

— A. Bartlett Giamatti (1938-1989) in “An Address to School Administrators’’ . Born in Boston and a Renaissance literature scholar, he served as president of Yale University in 1978-86, as National {baseball} League president in 1986-89, and for only five months as baseball commissioner in 1989, before suffering a fatal heart attack at his summer home, in Edgartown, Mass., on Martha’s Vineyard. He was a lifelong Red Sox fan.
