Harry H. Wellington, 84, whose half-century of studying and teaching law included a decade as dean of Yale Law School and eight years as dean of New York Law School, died Monday of a brain tumor at his home in New York.
Mr. Wellington made an early mark in labor law, enlivening what could be a drab and technical field with vivid ideas that drew on other disciplines and tested first principles. In his 1972 book, The Unions and the Cities, he argued that it could be dangerous to allow public labor unions to become too powerful. The argument, controversial at the time, anticipated the current debate over public unions.
