for the medal of honor recipient see phillip c katz phillip walter katz born 1962 11 03 november 3 1962 milwaukee wisconsin u s died april 14 2000 2000 04 14 aged 37 milwaukee wisconsin u s occupation computer programmer known for co creator of zip file format pkzip phillip walter katz november 3 1962 april 14 2000 was a computer programmer best known as the co creator of the zip file format for data compression and the author of pkzip a program for creating zip files that ran under dos a copyright lawsuit between system enhancement associates sea and katz s company pkware inc was widely publicized in the bbs community in the late 1980s katz s software business was very successful but he struggled with social isolation and chronic alcoholism in the last years of his life education and career edit phil katz was a graduate of nicolet high school in glendale wisconsin he graduated from the computer science engineering program at the university of wisconsin milwaukee 1 after his graduation he was hired by the allen bradley company as a programmer he wrote code to run programmable logic controllers which operated manufacturing equipment on shop floors worldwide for allen bradley s customers pkarc and pkware edit katz left allen bradley in 1986 to work for graysoft a milwaukee based software company at the time he had worked on an alternative to thom henderson s arc named pkarc arc was written in c with the source code available on system enhancement associates bulletin board system bbs pkarc written partially in assembly language was much faster katz had a special flair for optimizing code besides writing critical code in assembly language he would write c code to perform the same task in several different ways and then examine the compiler output to see which produced the most efficient assembly code he first publicly released only pkxarc an extraction program as freeware its much greater speed caused it to spread very quickly throughout the bbs community strong positive feedback and encouragement prompted katz to release his compression program pkarc and eventually to make his software shareware he founded pkware inc phil katz software in 1986 with the company s operations located in his home in glendale wisconsin 2 but he remained at graysoft until 1987 steve burg a former graysoft programmer joined pkware in 1988 pkzip edit main article pkzip pkzip made katz one of the most well known shareware authors of all time although pkware became a multimillion dollar company katz was more noted for his technical expertise than business prowess his family assisted him in running the company but he eventually fired them when they denied him access to the company s profits 3 katz was adamantly opposed to microsoft windows in the early 1990s citation needed this led to pkware missing out on the opportunity to be the first to bring pkzip to the platform with winzip becoming the standard tool on the platform instead lawsuits edit in the late 1980s a dispute arose between system enhancement associates sea maker of the arc program and pkware sea sued katz for trademark and copyright infringement the most substantial evidence at trial was from an independent software expert john navas who was appointed by the court to compare the two programs he stated that pkarc was a derivative work of arc pointing out that comments in both programs were often identical including spelling errors 4 on august 2 1988 the plaintiff and defendants announced a settlement of the lawsuit which included a confidential cross license agreement under the agreement sea licensed pkware for all the arc compatible programs published by pkware during the period beginning with the first release of pkxarc in late 1985 through july 31 1988 in return for an undisclosed payment pkware agreed to pay sea to obtain a license that allowed the distribution of pkware s arc compatible programs until january 31 1989 after which pkware would not license publish or distribute any arc compatible programs or utilities that process arc compatible files in exchange pkware licensed sea to use its source code for pkware s arc compatible programs pkware also agreed to cease any use of sea s trademark arc and to change the names or marks used with pkware s programs to non confusing designations the remaining details of the agreement were sealed in reaching the settlement the defendants did not admit any fault or wrongdoing 5 the wisconsin court order showed the defendants were ordered to pay damages to the plaintiff for the defendants acts namely the defendants were found to be infringing the plaintiff s copyrights infringing trademark as well as performing acts of unfair trade practices and unfair competition 6 the leaked agreement document revealed that under the settlement terms the defendants had paid the plaintiff 22 500 for past royalty payments and 40 000 for expense reimbursements in addition the defendants would pay the plaintiff a royalty fee of 6 5 of all revenue received for arc compatible programs on all orders received after the effective date of the agreement such revenue would include any license fees or shareware registrations received after the expiration of the license for arc compatible programs in exchange the plaintiff would also pay a commission in the amount of 6 5 of any license fees received by the plaintiff from any licensee referred to the plaintiff by the defendants whether before or after the license termination date 7 after the lawsuit pkware released one last version of its pkarc and pkxarc utilities under the new names pkpak and pkunpak and from then on concentrated on developing the separate programs pkzip and pkunzip which were based on new and different file compression techniques however following the renaming sea filed a lawsuit against pkware for contempt for continually using the plaintiff s protected mark arc by turning arc from noun into verb in the pkpak manual 8 the united states district court of the east district of wisconsin ruled sea s motion was denied and the defendant was entitled to recover the legal cost of 500 9 the sea vs pkware dispute quickly expanded into one of the largest controversies the bbs world had ever seen 10 the suit by sea angered many shareware users who perceived that sea was a large faceless corporation and katz was the little guy in fact at the time both sea and pkware were small home based companies however the community largely sided with katz because sea was attempting to retroactively declare the arc file format to be closed and proprietary katz received positive publicity by releasing the appnote txt specification documenting the zip file format and declaring that the zip file format would always be free for competing software to implement the net result was that the arc format quickly dropped out of common use as the predominant compression format that bulletin board systems used for their file archives and after a brief period of competing formats the zip format was adopted as the predominant standard alcoholism and death edit katz battled alcoholism for years the earliest known arrest occurred in 1991 about a year later katz was again convicted of drunk driving between 1994 and september 1999 katz was arrested five times for operating after suspension or revocation of his driver s license before his death ozaukee county sheriff s department had several outstanding warrants against katz including jumping bail and the charges of operating an automobile while intoxicated and operating after revocation 11 on april 14 2000 at the age of 37 katz was found dead in a hotel room with an empty bottle of peppermint schnapps in his hand a coroner s report stated his death was a result of acute pancreatic bleeding caused by chronic alcoholism 12 13 14 see also edit list of deaths through alcohol pklite references edit phil katz
