Bob was Honorably Discharged from the Air Force Drone Squadron at Tyndall AFB in Panama City, Florida and released to go to college in 1966. He graduated from Central Florida Junior College in 1969 and The University of West Florida in Pensacola, Florida, with a BS in Industrial Engineering in 1970. He was an engineer with Westinghouse Electric Company for many years and worked in both the nuclear and robotics divisions in Pensacola and later in Pittsburgh, Pennsylvania. Bob went to Japan as a Westinghouse engineer and was instrumental in building one of their Nuclear Power Plants. He moved to Cincinnati to work for a machine tool company, Cincinnati Milacron, and eventually ended up at Control Laser Corporation in Orlando, Florida in 1986. He wrote and published several articles in his field and held three patents for laser engraving and welding, built robots to inspect sewer lines, and invented a surveillance robot called PointMan.

Bob was talented in many ways. He was an inventor, an entrepreneur, and a musician. He played harmonica with a band called the Swinging Medallions throughout one summer in Panama City and became known for his version of the song, “Doubleshot of My Baby’s Love”. He called himself the Blues Doctor and enjoyed putting on shows playing keyboards and his harmonica blues. He rebuilt several Yamaha organs and played rock and roll for fun.

From his years in the Air Force, he developed many technical skills for fixing things. He could fix almost anything. He worked on TVs, radios, reel-to-reels, cars, and anything else mechanical. If he didn’t have a part and couldn’t get it, he would make it.

He helped a lot of people over the years and kept up with many old friendships. Bob developed and lived with disabilities for many years and endured it with dignity and humor. He was naturally cheerful and funny and most people, even the staff at the hospital during his many stays, appreciated his humor and Dad jokes.

Services for Bob and a celebration of his life will be held in the Chapel of Woodlawn Memorial Park, Orlando, FL on July 11, 2026, at 11:00 AM. Woodlawn Memorial Park and Funeral Home, 400 Woodlawn Cemetery Road, Gotha, Florida 34734.
