The University of Kansas’ Osher Lifelong Learning Institute recently launched a class studying the idiosyncrasies of the nation’s third president, Thomas Jefferson.

“Explaining the Perplexing Thomas Jefferson,” which began Tuesday at Ottawa University, largely examines the oddities of Jefferson’s behavior, according to a release from the institute. Two class periods remain, slated for 6:30 to 8:30 p.m. Tuesday and April 23 at OU’s Ward Science Building, 1001 S. Cedar St., Ottawa. The registration fee is $40 for all three sessions, the release said.

Norm Ledgin, author of “Diagnosing Jefferson,” is teaching the class, which also studies Jefferson’s self-indulgences, puzzling contradictions, relationship with slave Sally Hemings and other quirks, the release said.

The learning institute develops programs for people 50 and older, though it welcomes learners of all ages. In addition to Ottawa, courses are offered in Lawrence, Topeka, Olathe, Lenexa and Overland Park.
