With a final campus- and community-wide presentation, longtime Hesston College chemistry and astronomy professor Dr. Jim Yoder will kick off his last few weeks at the college before his retirement.

Yoder’s final Hesston College chapel presentation, “Integrating the Rainbow,” will be at 11 a.m., Monday, April 30, at Hesston Mennonite Church on the Hesston College campus. The 30-minute presentation is free and open to the public.

Yoder has served at Hesston College for 50 academic years, teaching his first class on September 9, 1968, while still working to complete a doctorate in organic chemistry with minors in physical chemistry and philosophy of science from Indiana University (Bloomington).

He also attended Hesston College for a year in 1961-62, and completed a degree in chemistry at Goshen (Ind.) College.
