Clinton E. Frank (September 13, 1915 – July 7, 1992) was an American football player and advertising executive. He played halfback for Yale University. In 1954, he founded the Clinton E. Frank, Inc. advertising agency.
Frank attended Yale College, where he was a member of Skull and Bones, and graduated with a degree in economics in 1938. In football, he was a two-time team captain and All-American, and as a senior in 1937, he won the Heisman Trophy and the Maxwell Award. He beat out Byron "Whizzer" White for the Heisman Trophy; White later became a justice of the U.S. Supreme Court. Frank also received the Maxwell Award after his senior year in which he scored three touchdowns in his team`s 19–0 victory over Brown.
Frank was drafted in the 12th round of the 1938 NFL Draft by the Detroit Lions, but he did not sign; he never played professional football.
Frank was married to Margaret Rathje Frank, with whom he had three sons and six daughters.
Frank joined the Chicago advertising firm of Blackett-Sample-Hummert Inc., where he was employed for ten years before being promoted to advertising manager of E.J. Brach and Sons, the famed candy producer. Frank became a full partner in the advertising agency of Price, Robinson and Frank. He was able to transition this agency into his own with him as owner and president. In 1954 Frank established Clinton E. Frank Inc., a Chicago based advertising agency which was sold to Campbell-Ewald Co. of Detroit in 1976.
One of Clinton E. Frank Agency's most memorable clients was the flashy Dallas-based Braniff International Airways. Frank obtained the account in 1969 from famed advertising executive George Lois. The Frank Agency created the "El Clan, Braniff" advertising scheme for Braniff's growing South American Route System. They also created the highly unique Braniff "You'll Like Flying Braniff Style" Campaign. Both campaigns came complete with musical jingles which were debuted in 1971.
