He graduated Wayland High School in 1953 and earned a Bachelor of Science degree from the School of Packaging, Michigan State University in 1957 at which time he also earned an AFROTC commission. Following flight training in Oklahoma in the summer of 1956, Robert married Judith Arlene Peffley. They were married for nearly 60 years.

In 1983 he joined LifeScan (Johnson & Johnson) in Palo Alto, CA and led product package engineering projects until he retired in 2000.

In recent years, Bob led volunteer efforts to maintain emergency radio "nets" and Ham Radio equipment for local hospitals in the CA East Bay. He enjoyed restoring antique Zenith radios to their former beauty and working condition. Genealogy research was another avid passion to the benefit of family. Bob is survived by his wife, Judy of Brentwood, his two children: Robert (& Anne) Hanlon of Pleasanton, CA and Patricia (& Keith) Teel of Southington, CT; and two grandchildren: Kayla & Bryson Teel. A brief graveside memorial will be conducted at the West Elmwood Cemetery, Wayland, MI Saturday, 10:00am on July 23, 2016 for family and friends. In his honor, in lieu of flowers, Bob would encourage donation, especially of blood, to the Red Cross, or to local blood banks as he was passionate about frequently donating his own blood for critical needs.
