Haven't You Ever Wondered Who Invented Clumping Cat Litter?

I have. I thought to myself: "this invention has improved my and my cat's life immeasurably, and I think it has been invented in my lifetime!" And I was right, since it was invented in 1976.

So who invented it? William Mallow, about whom I found the following tidbit:

2002 Honorary Unsubscribe Recipients: "4 August 2002's honorary unsubscribe went to William A. Mallow. A polymer chemist at the Southwest Research Institute, Mallow enjoyed working on practical problems. He showed M&M-Mars how to keep peanut butter from gunking up the molds at M&M candy factories. He helped Bette Nesmith Graham (mother of 'The Monkees' guitarist Michael Nesmith) perfect the formula for her invention, 'Liquid Paper'. He consulted on projects from Space Shuttle protective tiles to fake dinosaur skin -- and invented clumping cat litter. Mallow retired from SwRI in 1998, but continued to dabble in materials: most recently, he worked on the 'Mobility Denial System' -- a slippery spray that could be used to disable enemy troops without injuries or deaths. He died July 30 in San Antonio from leukemia. He was 72. "

I, for one, would love to see the videotapes of the practice sessions with the "Mobility Denial System."

According to the CBS News obit the "Mobility Denial" gel spray was due for introduction into use by the US military this year. Why don't we see this kind of footage on CNN? Is the enemy laughing too hard in those shots, as US tanks spin out on their own anti-mobility gel?
