Bob leaves an amazing legacy as a scientist - contributing to the field of cariology and many of the innovations for Crest/P&G Oral Care over the years [improving the health of billions of people]. We affectionately referred to Bob as the "tooth Fairy" and would showcase his work to CEOs and dignitaries alike [including a sitting President of the United States]. Most importantly, Bob was a great man - who loved his family and nurtured many, many deep friendships. We are all better - and blessed - for having had a chance to share-in his life's journey.
