Julius Wayne Reitz (December 31, 1908 – December 24, 1993) was an American agricultural economist, professor and university president. Reitz was a native of Kansas, and earned bachelor's, master's and doctorate degrees in his chosen field. After working as an agricultural economist, university professor and U.S. government agricultural administrator, Reitz was selected to be the fifth president of the University of Florida, serving from 1955 until 1967.

Wayne Reitz was born on New Year's Eve, 1908, in Olathe, Kansas. His parents later moved his family to Canon City, Colorado, where he graduated from high school in 1926, and was admitted to Colorado State University in Fort Collins, Colorado. While he was a university student, he was a member of Sigma Chi fraternity (Beta Tau chapter), the editor of the Silver Spruce yearbook, freshman class president, student body president, and the winner of the Rocky Mountain Oratory Award. Reitz received his bachelor's degree in 1930.

After graduating with a Bachelor of Science degree, Reitz started work as an agricultural extension economist, first at Colorado State, and then at the University of Illinois in Urbana-Champaign, where he earned his Master of Science degree in 1935. That same year, after accepting an assistant professorship in agricultural economics at the University of Florida in Gainesville, Florida, Reitz married Frances Huston Millikan. After being promoted to full professor, Reitz returned to his formal studies at the University of Wisconsin in Madison, Wisconsin, where he earned his Doctor of Philosophy degree in 1941.

Reitz left academic life in 1944 to work as an economic consultant for the United Growers and Shippers Association. Four years later, he became Chief of the Citrus Fruits Section in the U.S. Department of Agriculture (USDA). In 1949, President J. Hillis Miller prompted Reitz to return to the University of Florida by appointing him the university's provost for agriculture. During his time as provost, he was also appointed to the administrative boards of the Escuela Agrícola Panamericana in Tegucigalpa, Honduras, and the Instituto Interamericano de Ciencias Agrícolas de la OEA in Turrialba, Costa Rica.

University of Florida president J. Hillis Miller Sr.'s sudden and unexpected death in November 1953 started a lengthy search for his successor. In 1954, the Florida Board of Control named Philip G. Davidson, then president of the University of Louisville, as the university's new chief executive. Davidson, however, withdrew his name when controversial Acting Florida Governor Charley Johns refused to sign his payroll warrant. A new search was initiated and, two and a half months after Acting Governor Johns was replaced by the newly elected LeRoy Collins, the Board of Control settled on Reitz as its choice to be the university's fifth president on March 22, 1955. He was the first University of Florida faculty member to be elevated to the position.

During Reitz's term, more than 300 new campus buildings were erected at an approximate cost of $50 million. The buildings constructed and expanded during his term included a new health center, a nuclear training reactor, an educational television station, and a married-student housing complex. Along with the new buildings, Reitz tightened admissions standards and placed greater emphasis on academic achievement in matters ranging from the awarding of financial aid to the development of advanced placement procedures. Reitz expanded the graduate school through the addition of new programs and centers (especially the Latin American Language and Area Center) and created the Division of Sponsored Research to increase funding opportunities for research. His wife, a gracious hostess to countless dignitaries and students, also took an active role in advancing the university's music program. The facilities expansion coincided with a doubling of the student population from 9,000 to 18,000 during his tenure.

In 1960, Reitz was initiated as an honorary member of the Alpha Phi chapter of Alpha Kappa Psi.

The Reitz years were not without controversy. Strict behavior guidelines, dress codes, and a faculty disciplinary committee to enforce these rules all received Reitz's strong endorsement. In the early 1960s, the Florida Legislative Investigation Committee, led by state senator Charley Johns, accused twenty-two university employees and several students of homosexual conduct. Those that would not resign were summarily discharged or expelled. One attempted suicide. The denial of tenure to Marshall Jones, a psychiatrist active in radical causes, led to censure by the American Association of University Professors.^{[citation needed]}
