It sucks because he was my mentor as I grew as an engineer. Everywhere I look I find examples of what he taught me. Some of my thinking was molded by him. I have little engineering sayings and rules of thumb I got from him. Another friend of mine is the same. When we get together we invariably go into examples of how last week or last month we did X and it reminded us of him. I guess in a small way that makes him live on in our minds through what we do professionally every day.
