'''John Edward Warnock''' (October 6, 1940 – August 19, 2023) was an American [[computer scientist]], [[Invention|inventor]], technology businessman, and [[Philanthropy|philanthropist]] best known for co-founding [[Adobe Systems Inc.]], the graphics and publishing software company, with [[Charles Geschke]] in 1982.<ref name=Obit>{{cite news |title=John Warnock Obituary |publisher=The Salt Lake Tribune |date=August 24, 2023 |location=Salt Lake City, Utah |url=https://www.legacy.com/us/obituaries/saltlaketribune/name/john-warnock-obituary?id=52913731 |accessdate=August 26, 2023}}</ref> Warnock was President of Adobe for his first two years and chairman and CEO for his remaining sixteen years at the company. Although he retired as CEO in 2001, he continued to co-chair the Adobe Board of Directors with Geschke until 2017. Warnock pioneered the development of graphics, publishing, web and electronic document technologies that have revolutionized the field of publishing and visual communications.

== Career ==
Warnock is known as the creative driving force behind Adobe System's initial software products: [[PostScript]], [[Adobe Illustrator]], and the [[PDF]], and he continued to be involved in new product development throughout his career. "The thing I really enjoy is the invention process. I enjoy figuring out how to do things other people don't know how to do."<ref name=NYT>{{cite news |title=John Warnock, Inventor of the PDF, Dies at 82 |author=Clay Risen |newspaper=New York Times |date=August 24, 2023 |location=New York City, New York |url=https://www.nytimes.com/2023/08/24/technology/john-warnock-dead.html |accessdate=August 25, 2023}}</ref>

Warnock's earliest publication and subject of his master's thesis was his 1964 proof of a theorem solving the [[Jacobson radical]] for row-finite matrices,<ref>{{cite journal |jstor=1995321 |author= Sexauer NE and |year= 1969 |title=The Radical of the Row-Finite Matrices over an Arbitrary Ring |journal= Transactions of the American Mathematical Society |volume=139 |pages=281–295 |author2=Warnock, J.

In his 1969 doctoral thesis, Warnock invented the [[Warnock algorithm]] for [[hidden surface determination]] in [[computer graphics]].<ref>{{cite thesis

In 1976, while Warnock worked at [[Evans & Sutherland]], a [[Salt Lake City]]–based computer graphics company, the concepts of the [[PostScript]] language were seeded.<ref>{{cite web|url=https://spectrum.ieee.org/adobe-postscript|access-date=August 23, 2023|title=Inventing Postscript, the Tech That Took the Pain out of Printing|last=Perry|first=Tekla S.|date=May 1, 1988|work=IEEE Spectrum}}</ref> Prior to co-founding Adobe with Geschke, Warnock worked with Geschke at [[Xerox]]'s Palo Alto Research Center ([[Xerox PARC]]), where he had started in 1978.<ref name="Register obit">{{cite news |last1=Proven |first1=Liam |title=RIP: Computer graphics pioneer John Warnock dies at 82 |url=https://www.theregister.com/2023/08/21/john_warnock_obituary/ |access-date=August 22, 2023 |work=The Register |date=August 21, 2023 |language=en}}</ref> Unable to convince Xerox management of the approach to commercialize the [[InterPress]] graphics language for controlling printing on ''any'' computer and printer,<ref>{{cite web |title=Charles Geschke and John Warnock {{!}} Lemelson |url=https://lemelson.mit.edu/resources/charles-geschke-and-john-warnock |publisher=lemelson.mit.edu |access-date=August 22, 2023}}</ref> he and Geschke left Xerox<ref name="Register obit"/> to start Adobe in 1982, naming it after [[Adobe Creek (Santa Clara County)|Adobe Creek]], which ran behind both their homes.<ref name=WaPoObit/> They initially hired two computer scientists (Bill Paxton and Doug Brotz) and two electronics designers (Tom Boynton and Dan Putnam) from PARC.<ref>{{cite news |title=John Warnock, who helped invent the PDF, dies at 82 – CBS News |url=https://www.cbsnews.com/news/john-warnock-co-founder-adobe-systems-dies-82/ |access-date=August 22, 2023 |publisher=[[CBS News]] |date=August 21, 2023}}</ref><ref>{{cite web |title=Founding and Growing Adobe Systems, Inc |url=https://gwern.net/doc/design/typography/2019-warnock.pdf |access-date=August 25, 2023 |publisher=[[IEEE]] |date=June 18, 2019}}</ref> At their new company, they developed from scratch a similar technology, PostScript, and brought it to market for Apple's [[LaserWriter]] in 1985.<ref>{{cite news |last1=Kan |first1=Michael |title=John Warnock, Adobe Co-Founder Who Helped Invent the PDF, Dies at 82 |url=https://me.pcmag.com/en/news/18899/john-warnock-adobe-co-founder-who-helped-invent-the-pdf-dies-at-82 |access-date=August 22, 2023 |work=PCMag Middle East |date=August 21, 2023 |language=en-ae}}</ref> [[Apple, Inc.|Apple]] co-founder [[Steve Jobs]] said: "When that first page came out of the LaserWriter, I was blown away...No one had seen anything like this before.

In late 1986, Warnock invented [[Adobe Illustrator]], a computer drawing program that used lines and [[Bézier curve]]s to render infinitely scalable graphics. He initially developed it to automate many of the manual tasks utilized by his wife, Marva, a graphic designer.<ref>{{cite news |title=John Edward Warnock (Obituary) |publisher=Los Altos Town Crier |date=August 31, 2023 |location=Los Altos, California |url=https://www.losaltosonline.com/people/obituaries/john-edward-warnock/article_cf721fd0-475f-11ee-9bc4-7fabc3f3244c.html |accessdate=August 31, 2023}}</ref> Illustrator was released in early 1987.<ref>{{cite web |title=Adobe Explains It All: Adobe Illustrator |author=Anubhav Rohatgi |date=March 23, 2015 |publisher=Adobe Corporate Communications |url=https://blog.adobe.com/en/publish/2015/03/23/adobe-explains-it-all-illustrator |accessdate=August 11, 2023}}</ref>

In the spring of 1991, Warnock outlined a system called "Camelot", inventing the [[Portable Document Format]] (PDF) file-format.<ref name=NYT/> The goal of Camelot was to "effectively capture documents from any application, send electronic versions of these documents anywhere, and view and print these documents on any machines [sic]". Warnock's document contemplated:<ref>{{cite web |last=Warnock |first=John |year=1991 |title=The Camelot Project |url=http://www.planetpdf.com/planetpdf/pdfs/warnock_camelot.pdf |url-status=dead |archive-url=https://web.archive.org/web/20090304134754/http://www.planetpdf.com/planetpdf/pdfs/warnock_camelot.pdf |archive-date=March 4, 2009 |publisher=PlanetPDF |quote=This document describes the base technology and ideas behind the project named 'Camelot.'

The new PDF format, though, was slow to gain industry traction and Warnock noted that "the industry 'did not get it{{'"}}.<ref name="Eve">{{cite journal |last1=Eve |first1=Martin Paul |date=2022 |title=New Leaves: Riffling the History of Digital Pagination |url=https://muse.jhu.edu/pub/1/article/872063 |journal=Book History |volume=25 |issue=2 |pages=491 |doi=10.1353/bh.2022.0017 |s2cid=254221430 |access-date=August 25, 2023}}</ref>
