Phillip W. Katz, 37, creator of the popular PKZip programs and the ZIP archiving format, died unexpectedly on Friday, April 14. The cause was complications from chronic alcoholism, according to the Milwaukee medical examiner.
Katz first came to public attention in the early days of personal computers when he created PKArc, an archiving program that used the ARC format developed by System Enhancement Associates (SEA). The very popular ARC format helped bulletin board systems (BBSes) to flourish as a shareware distribution mechanism by making downloads smaller and quicker. SEA sued to prevent Katz from using its format.
After settling the suit, Katz developed the ZIP format and published PKZip, which he allowed individuals to use for free. Anger in the BBS community at SEA for its lawsuit brought about almost immediate adoption of ZIP as the preferred format, and Katz was on his way to success.
In addition to allowing non-commercial users free use of the program, Katz dedicated the ZIP file format specification and the ZIP file extension to the public domain, a move that allowed the development and success of WinZip and other Zip utilities.
PKZip was generally considered to be faster and more reliable than other compression techniques, as well as producing smaller compressed files.
In a 1993 interview with the Milwaukee Journal, Katz said the idea behind PKZip began at his mother’s kitchen table in 1986. "It was just a hobby," he said. "I didn’t expect it to turn into a business."
