I first met Bob around 2005, working on Guice together. Later, when my startup was trying to get attention, he introduced me to the Google Docs team, which led to our acquisition. I'm still at Google 16+ years later, which very likely wouldn't have happened without Bob's involvement. He was always good about keeping in touch, even though he obviously had a huge number of friends and colleagues in his life. I'm sure many people have similar stories about how Bob's help or advice changed their lives for the better.
