A triple major in college (chemistry, physics, mathematics), Haworth received his bachelor's degree from the University of Wisconsin-Oshkosh in 1950, master's degree in chemistry from Marquette in 1952, and Ph.D. in chemistry at St. Louis University in 1959. He began his academic career as an assistant professor at Marquette in 1959, retiring as an emeritus professor of chemistry in 2009.
During his 50-year career at Marquette, he taught more than 18,500 students, published more than 200 scholarly papers and held 19 patents. He co-founded Marquette’s Freshman Frontier Program for students identified as having the potential to succeed at Marquette but who may require extra help to do so. He also received Marquette’s highest teaching honor, the Pere Marquette Award for teaching excellence, in 1971.
