A Virginian and a graduate of the University of Virginia, Frost began his remarkable career with two decades of service in the United States Public Health Service. He investigated epidemics of yellow fever, typhoid, polio, streptococcal sore throat, meningitis, and influenza. His greatest contributions duringthis part of his career were the recognition that mild and asymptomatic childhood polio produced life-long immunity and the development of methods for tracking influenza epidemics. He was recruited to Johns Hopkins in 1919, where,as a Professor at the School of Hygiene and Public Health, he trained many of the future leaders of American public health programs. He made substantial contributions to epidemiologic methodology including developing the conceptof an index case during investigations of tuberculosis in Tennessee, the use of life-table methods for estimating secondary attack rates, the use of age cohorts for longitudinal studies, and, in collaboration with Lowell Reed, thefirst mathematical expression of the epidemic curve. \u003cbr\u003e Thomas M.
