Frederic "Freddie" Stanley Dunn[1][note 1] (August 3, 1872 – January 7, 1937) was an American scholar of classical studies on the faculty of the University of Oregon (UO), and a Ku Klux Klan leader.

He became a full professor, at age 26, in 1898 upon the death of the senior faculty member, Prof. John Wesley Johnson.

[6][4] According to historians David Alan Johnson, Quintard Taylor and Marsha Weisiger, in their 2016 report to the university: Dunn resumed teaching duties at the University of Oregon and soon developed a regional and eventually national reputation as a classics scholar and over the course of his career published over 70 articles in scholarly journals, newspapers, and magazines...

[13] He was a secretary in the Salem Choral Society,[14] Native Sons organization in Oregon[15] and the Epworth League[16] and the Classical Association of the Pacific Northwest.

His military career began by drilling with students on the university campus, and he eventually became an assistant chief of staff for the Oregon training camp.

[4] The Klan was very active in Eugene, where it had some success in removing Catholics from public office and teaching positions.

The university named a dormitory in his honor, part of the Hamilton Complex built in 1961, "Dunn Hall".

Demands by the Black Student Task Force in November 2015 led University President Michael Schill to commission three historians to report on racist beliefs and the Klan affiliation of Dunn, as well as the pro-slavery position of Matthew Deady, the first president of the university's board of regents, after whom Deady Hall was named.
