Here is a photo of Bill at our 20th reunion in 2006 - having fallen out of touch over the years - it was a treat to spend time with him again. (from left to right, Mark Goodkin, Bill Gilbert (sticking tongue out), Brad Foltz and me – Eric Meier

He dressed like a biker - leather, mustache, skull rings - but was truly a gentleman in the best sense and the world is a lesser place without Bill in it. I am heartbroken as all who knew him are.
His online obit is here.
