Philip Katz died April 14th (and the news sources are just now covering this. Sheesh!) at the age of 37. While you may not recognize the name right off the bat, you might recall some programs like PKARC and more importantly PKZIP. Philip was the father of the ZIP compression algorithm. ABC News has this story. Found this first on User Friendly, and also read it on Slashdot. Goodbye PK... Compression will never be the same without you.
