We will all miss the "absolute genius" Robin Williams, according to the US Secretary of State John Kerry.
He was an absolute genius, with an extraordinary zest for his profession. It's safe to say that there was more going on in him in one minute than most people in a week. He loved people and he committed himself to any issue that concerned him.
Robin wasn't just a huge creative genius, but a caring, involved citizen. I'll always be grateful for his personal friendship and his support for the causes that we both cared about deeply.
We will all miss Robin's uncanny impressions, zany observations, and cutting-edge quips that found the truth as well as the humor. Teresa and I join the millions he inspired around the world in offering our deepest condolences to his family at this immensely difficult moment.
