Henry E. Frnka (; March 16, 1903 – December 18, 1980) was an American football player, coach, and college athletics administrator. He served as the head coach at the University of Tulsa from 1941 to 1945 and at Tulane University from 1946 to 1951, compiling a career college football record of 71–32–5. Frnka was also the athletic director at Tulsa from 1941 to 1945.
Frnka began his coaching career at the high school level. He served as the head football coach at Lubbock High School in Lubbock, Texas, from 1926 to 1930 before moving to Greenville High School in Greenville, Texas, in 1931.[1] He led the Greenville Lions to a Texas state championship in 1933. He used the fumblerooski for the very first time in the 1933 Texas High School Championship game.
Frank left Greenville in 1936 to become freshman coach at Vanderbilt University. He was briefly succeeded at Greenville by his assistant, Dennis Vinzant.[2]
From 1941 to 1945, Frnka coached at the University of Tulsa, and compiled a 40–9–1 record. The Tulsa Golden Hurricane had never been to a bowl game before, and he took them to five straight, becoming Tulsa's most prolific coach. The Golden Hurricane won three league titles, and outscored opponents 1,552 to 375. He led the team to their first bowl game and a school-best national ranking of No. 4 at the end of the 1942 season.
From 1946 to 1951, Frnka coached at Tulane University, and compiled a 31–23–4 record. Since the 1920s, the Tulane Green Wave had been a national power in college football, and Frnka-led teams produced records of 9–1 in 1948, 7–2–1 in 1949, and 6–2–1 in 1950. In a 1949 issue devoted to a preview of that year's college football season, SPORT magazine declared that Tulane was the best team in the country.
Frnka died on December 18, 1980, in San Antonio, Texas, at the age of 77.[3]
