Peterson came from Lawrence University to become the first lay president of the University of Dubuque in 1970. He arrived at a time of increasing student activism, declining enrollments and dwindling revenues. Peterson was given credit for reversing the status of the university by his ability to persuade others to work with him. One of his ideas led to the establishment of the Dunlap Lecture Series that invited such celebrated economists as Martin Feldstein and John Kenneth Galbraith to Dubuque to give lectures. He also organized many art exhibits with the university which frequently featured the work of local artists. (4) Peterson, the longest-serving president of the University of Dubuque, retired in 1990 and was succeeded by John J. AGRIA. He then served as the school's first and only chancellor from 1990 to 2000. (5)
Peterson served as chairperson from 1981 to 1983 of the Iowa College Foundation. He was president of the Iowa Association of College and University Presidents from 1974 to 1975 and the Iowa Association of Independent Colleges and Universities. (6)
While living in Milwaukee, Peterson was commissioned to write the history of Allis-Chalmers Manufacturing Company. Over the years, he wrote business histories of the WILLIAM C. BROWN COMPANY and the Hawkeye Bancorporation. (7)
Locally Peterson served on board of directors of FINLEY HOSPITAL (THE), Finley Foundation, DUBUQUE MUSEUM OF ART, DUBUQUE COUNTY HISTORICAL SOCIETY, GRAND THEATER, Four Mounds Foundation and the DUBUQUE SYMPHONY ORCHESTRA. (8)
Peterson shared the 1990 FIRST CITIZEN AWARD from the TELEGRAPH HERALD with William G. KRUSE. In 2007 he received the "Treasures of Dubuque" honor from the DUBUQUE COUNTY HISTORICAL SOCIETY.
