T. Coleman Andrews was an exceptional accountant whose career during the second quarter of this century spanned professional accounting practice, public service, military service and business management. This paper documents his contributions to accounting and administrative reform through the public-service positions he held in government at local, state and national levels. Earlier work by Flesher and Flesher (1989) focused on his contributions to operational auditing during his years at the General Accounting Office, and these contributions are reviewed here. In addition, this paper describes his later work with the Hoover Commission and as commissioner of the Internal Revenue Service.
