William Johnston (8) (1960–)

[excerpted from Butler University website]
“Dr. J.” has taught mathematics to undergraduates for more than 40 years. He also served for 17 years in administrative posts ranging from department chair, associate dean, and academic affairs vice president at various institutions. The pinnacle of this work was from June 2011 to January 2018 as chair of Butler University's Department of Mathematics, Statistics, and Actuarial Science, which culminated in the Liberal Arts and Sciences award for outstanding faculty member in service to the College.

He has developed and implemented new courses into the undergraduate curriculum at several institutions. They include: Integration Theory, which teaches the Lebesgue Integral to undergraduates; Foundations of Mathematics, which teaches how to prove mathematical theorems, much like an art course might teach how to paint; the FYS course Elementary, my Dear Watson, which looks at characters such as Sherlock Holmes in literature, drama, and film who illustrate the use of deductive and inductive reasoning; and Decision Making, which shows how many different disciplines — such as mathematics, economics, ethics, and English literature — can influence the way people make decisions.

His third textbook in mathematics, on the Lebesgue integral, and his fourth book, on complex variables, are both published by the highly acclaimed AMS/MAA Press.
