He’s been a fixture at Kansas University for more than half a century, but now a longtime political science and law professor is leaving Lawrence.

Francis Heller, 91, came to the university in 1948 and even though he officially retired 20 years ago, Heller continued to teach classes until 2003 and has maintained an office at Green Hall.

Friday, Heller cleaned out that office as he prepares to move to Denver to be closer to family.

In addition to his teaching duties, Heller served as vice chancellor for academic affairs and twice worked as acting provost.

During his career, Heller authored 17 books and wrote nearly 200 articles and book reviews.

Heller also assisted President Harry S. Truman with his memoirs and served as the vice president of the Harry S. Truman Library Institute for more than 30 years.
