I'm very sad to hear of the sudden passing of my BBN colleague Ray Tomlinson at age 74. If you use email, he invented it in 1971 as a fun side project, just one of his many inventions. He was the best software engineer I ever encountered in my career. He often took good code and made it much, much better. His own code tended to be closer to perfect from the get-go. He was kind enough to show us the hows and whys in his thinking. You could go to him for advice and he would give you great guidance. He was kind and encouraging. I worked with him on a dozen projects from logistics to scheduling to mapping to intelligent agents to distributed computing to fixing the JVM, and he was always the mark of excellence. There are hundreds of BBNers who have many Ray stories. He made it a point to come to work at 7:30 and leave at 4:30, he got more done than anyone, and I don't remember him ever being behind, even as he took time to help the rest of us. He was and is legend. Ray, you were awesome!
