In 1968, Hayflick was appointed Professor of Medical Microbiology at the Stanford University School of Medicine, Stanford, California. Hayflick resigned from Stanford in 1976 in protest to the behavior of a few of its administrators who were later shown to have wrongly accepted the beliefs of an NIH accountant who was unable to understand the unique concept of title to a self-duplicating biological system. Hayflick sued the NIH, who later agreed that the issue was in dispute. The behavior of Stanford and the NIH was later condemned by 85 prominent biologists who viewed him as having been "exonerated" by subsequent events. In 1982 he moved to the University of Florida, Gainesville, where he became Director of the Center for Gerontological Studies and Professor of Zoology in the College of Liberal Arts and Sciences and Professor of Microbiology and Immunology in the College of Medicine.
