Tobin illustrated Harry's influence in terms of publications, citations, contributions to lectures, conferences and symposia, journal editing, and a “far flung, numerous and devoted band of students, friends and admirers” (444). He elaborated four reasons for his influence: his willingness to accommodate fellow scholars and students; his powers of exposition and synthesis informed by an almost limitless knowledge of the literature; his internationalism; and his status as a “character” in a profession with few colourful personalities. Graduate students at LSE used to refer to him as “big Harry.”

Harry was, as C. P. Kindleberger remarked, “one who never did anything by halves: writing, editing, eating, drinking, smoking and, after giving up smoking, whittling” (1991, 151).

His passing was marked as few are in economics. There was a notice by A. R. Prest in The Economist, which in those days did not normally publish obituaries.
