Leary graduated in 1968 from Rice Lake High School, where he played tackle for the 1966 Heart o’ North championship football team [3] and competed in the state wrestling tournament.[4]
While in high school, he spent a year at Scotch College in Melbourne, Australia. He played loose forward on the rugby team, which won the premiership of Victoria.[5]
His parents and paternal grandparents were journalists, all graduates of the Columbia University School of Journalism, as was his brother Mike, the first third-generation graduate of the school. His father, Warren D Leary Jr., was editor and publisher of the weekly Rice Lake Chronotype,[6] succeeding his grandfather, Warren D Leary, who also served a term in the Wisconsin legislature.[7]
His brother, Mike Leary, was the editor of the San Antonio Express-News, and while at the Philadelphia Inquirer, directed and edited a series on school violence that won the 2012 Pulitzer Prize for public service.[8]
Leary received his B.A. in literature from the University of Notre Dame in 1972. In 1973, he earned his M.A. in folklore from the University of North Carolina. Leary earned his PhD in folklore and American studies from Indiana University in 1977. His research focuses on the folklore of the Upper Midwest, especially Scandinavian Americans, indigenous and immigrant people, and rural and working-class peoples.[9] Leary teaches at the University of Wisconsin–Madison in the Scandinavian Studies Department and the Department of Comparative Literature and Folklore Studies.[10] In 2012, he was a Fulbright Scholar in Iceland.[11]
In his book, Polkabilly: How the Goose Island Ramblers Redefined American Folk Music, Leary proposes a redefinition of traditional American folk music and proposes a new genre known as "Polkabilly".[15]
Leary is a Fellow of the American Folklore Society. The Fellows of the American Folklore Society honor folklorists who have made outstanding contributions to the field of folklore.[16]
Together with Thomas A. DuBois, he served as co-editor of the Journal of American Folklore.[17]
Dealing with the era at Notre Dame before coeducation, Leary has contrasted two self-images of the Notre Dame student. They coexist uneasily, the first appearing in official documents the second in popular culture.
Two opposing cultural systems have long coexisted at the University of Notre Dame. The former is normative, overt, official while the latter is deviant, largely covert, and unofficial. Catholicism, academic excellence, and athletics are prominently featured in university publications, in the rhetoric of administrator and alumni, and in serious histories of the campus. Meanwhile, the drunken rowdiness of sex-starved, animalistic dirtballs is confined to dormitory rooms, the talk of students, occasional periods of license, and playful ephemeral publications. Both systems have been integral to the experience of Notre Damers.[18]
In 2006, Leary won the Chancellor's Award for Excellence in Teaching.[10]
In 2007, he was co-winner of the American Folklore Society’s Chicago Folklore Prize for the best book in the field of folklore scholarship for Polkabilly: How the Goose Island Ramblers Redefined American Folk Music.[20]
In 2015, Leary's Folksongs of Another America: Field Recordings from the Upper Midwest, 1937–1946 was nominated for a Grammy in Best Album Notes by the National Academy of Recording Arts & Sciences.[22]
In 2016, Leary's Folksongs of Another America: Field Recordings from the Upper Midwest, 1937–1946 was awarded the Best Historical Research in Recorded Folk or World Music from the Association for Recorded Sound Collections.[23]
In 2019, Leary received his second Grammy Award nomination in Best Album Notes for his 60-page booklet accompanying Archeophone Records’ double CD ‘’Alpine Dreaming: The Helvetia Records Story, 1920-1924.’’ The music is from a short-lived Swiss folk record label based in Monroe, Wis.[24]
