Looking for some historical information

As I am interested in Ada 83 preservation and history (and working on reviving the Peregrine Ada/DIANA translator), I am also interested in people who worked in the field.

I would like to know who was Dr. William “Bill” Easton.

On the internet I found William Edward Easton (1942-2016) - Find a Grave Memorial for someone who worked as general contractor in Virginia.

W.Easton was mentioned as present in the verification panel of a SDS (Strategic Defense System) review in 1989. His address was at Peregrine Bluemont Virginia.

Is there anybody having some indications about Mr. Easton ?
