Phillip W. Katz, better known as Phil Katz (November 3, 1962April 14, 2000), was a computer programmer best-known as the author of PKZIP, a program for compressing files which ran under the PC operating system DOS.

Early Life

He received a bachelor's degree in computer science from the University of Wisconsin at Madison.

His first compression product was released in the mid-1980s with a program called PKARC. PKARC was compatible with the then-popular ARC program. ARC, which was distributed along with the source code, was written in C. PKARC, written partially in assembly language, was much faster. PKARC's speed quickly made it more popular than the earlier program.

However, System Enhancement Associates, soon discovered that Katz had copied significant amounts of the copyrighted source code distributed with ARC. They sued for trademark violation and copyright infringement, and won: Katz was forced to change the program.[1] According to expert witnesses hired by SEA, Katz had copied ARC's source code so extensively that even identical comments and spelling errors were found. Katz withdrew PKARC from the market, and instead released PKPAK, which was similar in all but name. The BBS community, arguably due to prompting from Katz, took the suit as an example of a large, faceless corporation crushing the little-guy — even though both companies were family businesses with less than 5 or so people. SEA's founder, Thom Henderson, has said that users who spoke to him at the time "didn't care" if PKARC copied his intellectual property; they just wanted to use the fastest software to compress and uncompress files.[2]

This whole debacle was considered extremely controversial and Katz's version of the story in his own words will forever remain unknown.

PKZIP

Katz soon replaced PKPAK with the new and completely re-written PKZIP, released as shareware, which compressed both better and faster than ARC. Katz kept the new ZIP file format open. As a result, it soon became a standard for file compression across many platforms.

PKZIP made Katz one of the most successful shareware authors of all time. Although his company PKWARE became a multimillion dollar company, Katz hired people he trusted to run the company and continued writing software himself.

Death

Katz battled alcoholism for years. His friends tried to help him with his addiction, but they were rebuffed, and he gradually shut them out completely. He was arrested several times for driving under the influence, and later in his life, spent more time in cheap motels and strip clubs than his own home.[3]

Katz was found dead in a hotel room with an empty bottle of peppermint schnapps in his hand on April 14, 2000 at the age of 37. A coroner's report stated his death was a result of pancreatic bleeding caused by acute alcoholism.

A computer program or software program (usually abbreviated to "a program") is a step-by-step list of instructions written for a particular computer architecture in a particular computer programming language. A layman equivalent example would be writing a step-by-step list of instructions in English instructing a human how to make a Peanut butter and jelly sandwich (the human being the specific architecture).

In computer science, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than a more obvious representation would use, through use of specific encoding schemes. For example, this article could be encoded with fewer bits if we accept the convention that the word "compression" is encoded as "comp".

A personal computer or PC is generally a microcomputer intended to be used by one person at a time, and suitable for general purpose tasks such as word processing, programming, sending messages or digital documents (comprising of text, images, audio or video) to other computers on the network (email), multimedia editing or game play, usually used to run software not written by the user.

The acronym DOS stands for disk operating system, an operating system component for computers that provides the abstraction of a file system resident on hard disk or floppy disk secondary storage. In some cases, the disk operating system was called DOS, and on the PC compatible platform, an entire family of operating systems was called DOS.

Shareware is a marketing method for software, whereby a trial version is distributed in advance and without payment, as is common for proprietary software. Shareware software is typically obtained free of charge, either by downloading from the internet or on magazine cover-disks. A user tries out the program, and thus shareware has also been known as 'try before you buy', demoware, trialware and by many other names.

Driving under the influence, drink-driving, or drunken (often called drunk) driving, is the act of operating a motor vehicle after having consumed alcohol (ethanol) or other drugs, to the degree that mental and motor skills are impaired. It is illegal in most jurisdictions. Several anti-drink-driving advertising campaigns have aimed to raise awareness of the legal situation and the dangers of driving while intoxicated.

Schnapps is a type of distilled beverage. The word Schnapps is derived from the German word Schnaps and refers to usually clear alcoholic beverages distilled from fermented cereals, roots or fruits, including cherries (Kirschwasser), apples, pears, peaches, plums and apricots. Often, the base material for making schnapps is the pulp that is a by-product in juice production. True Schnapps has no sugar or flavoring added.
