HARRISON SHULL BUILT AN influential scientific career in research, specializing in the quantum mechanics of small-molecule electronic spectra. He later showed a gift for administration as a chief academic officer of several major educational institutions. He was born into a family of highly achieving scholars and scientists; a hefty book titled Shull Genealogy was a proud part of his early personal library. It was clear that this background contributed strongly to his self-confidence and growth, and it can also be stated that he added much luster to the already illustrious Shull name.
Harrison Shull made early, seminal contributions to the theory of molecular energy levels, taking advantage of the growing capabilities of large-scale computers in the decades of the 1950s and 1960s. As his career developed, he found ways to promote the use of computers in chemistry, increasingly using his administrative talents to the great benefit of his colleagues in acquiring access to these facilities
Harrison Shull was born in Princeton, New Jersey, where his father, George Harrison Shull, was a professor of botany at Princeton University. George Shull had become famous for his part in the development of hybrid corn, which had
