from Robert Tibshirani

I first encountered Sam at a Statistical meeting a few years back, when I attended a talk that he was giving. He really bowled me over. I was just amazed by his energy and the clarity of his presentation. I came away thinking: now that's how you give a seminar! He really inspired me to try to improve my own presentations. Last year I visited him at Google and he was generous and brimming full of ideas: a wonderful person to be around. This is a great loss. My heart goes out to his family.
