Robert P. Nelson Jr., M.D,.67, of Indianapolis, passed away on December 9, 2021 at Franciscan Health in Indianapolis.

He grew up on the west side of Evansville, where he attended Reitz High School, playing varsity football and basketball. Bob was quarterback for the historic 1971 state-champion football team.

An accomplished and respected physician and Immunologist, Robert practiced at I.U. Health and Riley Children’s Hospital in Indianapolis. Additionally, he was a professor at the Indiana University School of Medicine, inspiring many current and future physicians to pursue immunology as a specialty.

Dr. Nelson was engaged in allergy/immunology research throughout his career, authoring numerous publications and receiving a range of awards for both his research achievements and teaching excellence.

A multi-talented man, he enjoyed playing his guitar and piano as well as listening to all genres of music.
