Theodore W. Gray is one of the founders of Wolfram Research and is currently Wolfram's Director of User Interface Technology.
He is a prominent element collector and created a wooden periodic table with compartments for samples of each of the elements. This table won him an Ig Nobel Prize in Chemistry in 2002.
He writes a regular column for Popular Science entitled "Gray Matter", which in 2009 were published as a collection in a book titled Mad Science: Experiments You Can do at Home—But Probably Shouldn't. He was nominated for a 2010 National Magazine Award for Best Column, but didn't win. Additionally, he wrote the introduction to Michael Swanwick's The Periodic Table of Science Fiction.
He founded the company Element Collection in late 2006 to primarily sell a full color photo periodic table poster he created.
Wolfram Research co-founder Theo Gray talks about the importance of risk in science education -- is a good experiment worth dying for? (Maybe just a little bit.)
