I'll just quote my brother-in-law's brief biographical sketch from Facebook:
Major Richard Brubaker (retired) passed away on Monday. He was a veteran of WWII and the Korean Conflict. He also served during the Cold War where he studied photos of Cuban Missile sites. He was a prime example of what is called "the Greatest Generation". He always thought of others. His family and friends always came first. He will be missed.
It took the Grim Reaper 93 years to catch up to him, despite a wealth of opportunities, starting when Richard fell down a well in Kansas as a small child and got stuck, which is apparently a thing that happened regularly in the nineteen thirties, at least according to Radio Days.
He fought in the Pacific, aboard the U.S.S. Saratoga. After the war he joined the Air Force, went through Officers Training School, then served in Korea, and flew as part of some truly hair-raising surveillance flights during the height of the Cold War. He was a good storyteller and I always found it frustrating that he wouldn't talk about those experiences much, and when he did it was always a brief, funny anecdote with himself as the butt of the joke.
He was endlessly kind, hilariously self-deprecating, and quietly badass.
