I first met Mr. Allen in 1998, some time after Elizabeth and I started dating. I am not normally overwhelmed by people who claim to be brilliant or smart but fail to exhibit those traits. However, Mr. Allen was different in that regard: he showed himself to be brilliant and smart in many ways.
As time went on Mr. Allen was always willing to offer helpful input about various issues that would come up within the family or things political or spiritual.
I have come to believe that Mr. Allen was indeed what I would call a polymath. A polymath (Greek: p???µa???, polymathes, "having learned much"), sometimes (if male) referred to as a Renaissance Man, is a person whose expertise spans a significant number of different subject areas. In less formal terms, a polymath (or polymathic person) may simply be someone who is very knowledgeable.
Indeed, a renaissance man. Mr. Allen was a man who made himself feel useful and needed by helping others with his knowledge.
It was only after Mr. Allen went to the greater reward that I was able to appreciate how many areas that he spent significant time learning to the point of expertise: Coin collecting, bible reading and comparison of not just one or two bibles but a dozen or more. These are just a few areas that I can think of but I know there are many more.
Mr. Allen: You will be missed.
