Paul Allen

Paul Gardner Allen (January 21, 1953 – October 15, 2018) was an American businessman, computer programmer, and investor. He co-founded Microsoft Corporation with his childhood friend Bill Gates in 1975, which was followed by the microcomputer revolution of the 1970s and 1980s. Allen was ranked as one of the richest people in American history by Forbes, with an estimated net worth of $20.3 billion at the time of his death in October 2018.

Allen quit day-to-day work at Microsoft in early 1983 after a Hodgkin lymphoma diagnosis, remaining on its board as vice-chairman. He and his sister, Jody Allen, founded Vulcan Inc. in 1986, a privately held company that managed his business and philanthropic efforts. At the time of his death, he had a multi-billion dollar investment portfolio, including technology and media companies, scientific research, real estate holdings, private space flight ventures and stakes in other sectors. He owned the Seattle Seahawks of the National Football League and the Portland Trail Blazers of the National Basketball Association, and was part-owner of the Seattle Sounders FC of Major League Soccer. Under the Allen Estate's helm, the Seahawks won Super Bowl XLVIII, LX, and made it to two other Super Bowls (XLIX, XL). In 2000 he resigned from his position on Microsoft's board and assumed the post of senior strategy advisor to the company's management team.

Allen founded the Allen Institutes for Brain Science, Artificial Intelligence, and Cell Science, as well as companies like Stratolaunch Systems and Apex Learning. He gave more than $2 billion to causes such as education, wildlife and environmental conservation, the arts, healthcare and community services. In 2004, he funded the first crewed private spaceplane with SpaceShipOne. He received numerous awards and honors and was listed among the Time 100 Most Influential People in the World in 2007 and 2008. He also discovered the wrecks of various famous warships, like the Japanese battleship Musashi and USS Indianapolis.

Allen was diagnosed with non-Hodgkin lymphoma in 2009. He died of septic shock related to cancer on October 15, 2018, at the age of 65. Shortly after his death, in April 2019, the Allen-funded Stratolaunch first flew and became the largest aircraft in history by wingspan.

Allen was born on January 21, 1953, in Seattle, Washington, to Kenneth Sam Allen (a librarian) and Edna Faye (née Gardner) Allen (a fourth-grade teacher). From 1965 to 1971 he attended Lakeside School, a private school in Seattle where he befriended Bill Gates, with whom he shared an enthusiasm for computers. They used Lakeside's Teletype terminals to develop their programming skills on several time-sharing computer systems. They also used the laboratory of the Computer Science Department of the University of Washington for personal research and computer programming until they were banned in 1971 for abusing their privileges.

Gates and Allen joined with Ric Weiland and Gates' childhood best friend and first collaborator, Kent Evans, to form the Lakeside Programming Club and find bugs in Computer Center Corporation's software, in exchange for extra computer time. In 1972, after Evans' sudden death in a mountain climbing accident, Gates turned to Allen for help finishing an automated class scheduling system for Lakeside. They then formed Traf-O-Data to make traffic counters based on the Intel 8008 processor. According to Allen, he and Gates would go dumpster diving during their teenage years for computer program code.

Allen achieved a perfect SAT score of 1600 and went to Washington State University, where he joined the Phi Kappa Theta fraternity. He dropped out of college after two years to work as a programmer for Honeywell in Boston near Harvard University where Gates was enrolled. Allen convinced Gates to drop out of Harvard in order to focus on Microsoft.

Allen and Gates formed Microsoft in 1975 in Albuquerque, New Mexico, and began marketing a BASIC programming language interpreter, with their first employee being high school friend and collaborator Ric Weiland. Allen came up with the name of "Micro-Soft", a combination of "microcomputer" and "software".

Microsoft committed to delivering a disk operating system (DOS) to IBM for the original IBM PC in 1980, although they had not yet developed one, and Allen spearheaded a deal for Microsoft to purchase QDOS (Quick and Dirty Operating System) written by Tim Paterson who was employed at Seattle Computer Products. As a result of this transaction, Microsoft secured a contract to supply the DOS that ran on IBM's PC line, which opened the door to Allen's and Gates' wealth and success.

The company restructured on June 25, 1981, to become an incorporated business in its home state of Washington (with a further change of its name to "Microsoft Corporation, Inc."). As part of the restructuring, Gates became president of the company and chairman of the board, and Allen became executive vice president and vice chairman. The relationship between Allen and Gates became strained as they argued even over small things. Allen effectively left Microsoft in 1982 after being diagnosed with Hodgkin's lymphoma, though he remained on the board of directors as vice chairman. Gates reportedly asked Allen to give him some of his shares to compensate for the higher amount of work that Gates was doing. According to Allen, Gates said that he "did almost everything on BASIC" and the company should be split 60–40 in his favor. Allen agreed to this arrangement, which Gates later renegotiated to 64–36. In 1983, Gates tried to buy Allen out at $5 per share, but Allen refused and left the company with his shares intact; this made him a billionaire when Microsoft went public, with 25.2% ownership of the company. Gates later repaired his relationship with Allen, and the two men donated $2.2 million to their childhood school Lakeside in 1986. They remained friends for the rest of Allen's life.

Allen resigned from his position on the Microsoft board of directors on November 9, 2000, but he remained as a senior strategy advisor to the company's executives. In January 2014, he still held 100 million shares of Microsoft.

Vulcan Capital is an investment arm of Allen's Seattle-based Vulcan Inc., which has managed his personal fortune. In 2013, Allen opened a new Vulcan Capital office in Palo Alto, California, to focus on making new investments in emerging technology and internet companies.

Patents: Allen held 43 patents from the United States Patent and Trademark Office.

Apps: Allen backed A.R.O., the startup behind the mobile app Saga; SportStream, a social app for sports fans; and a content-management app called Fayve.

Interval Research Corporation: In 1992, Allen and David Liddle co-founded Interval Research Corporation, a Silicon Valley–based laboratory and new business incubator that was dissolved in 2000 after generating over 300 patents, four of which were the subject of Allen's August 2010 patent infringement lawsuit against AOL, Apple, eBay, Facebook, Google, Netflix, Office Depot, OfficeMax, Staples, Yahoo!, and YouTube.

Ticketmaster: In November 1993, Allen invested more than $325 million to acquire 80% of Ticketmaster. In 1997, Home Shopping Network acquired 47.5% of Allen's stock in exchange for $209 million worth of their own stock.

Allen gave more than $2 billion towards the advancement of science, technology, education, wildlife conservation, the arts, and community services in his lifetime.. Allen Family Philanthropies (previously known as The Paul G. Allen Family Foundation), which he founded with his sister Jody, was established to administer a portion of Allen's philanthropic contributions. From 2016 to 2026, the foundation had given more than $500 million to hundreds of nonprofits. In 2025, a new second foundation was established named Fund for Science and Technology, funded initially with $3.1 billion from his Estate, and committed to invest at least $500 million over the next four years toward its mission of accelerating discovery and catalyzing progress for people and planet through transformational science and technology.

In 2010, Allen had become a signatory of The Giving Pledge, promising to give at least half of his fortune to philanthropic causes. Allen received commendations for his philanthropy, including the Andrew Carnegie Medal of Philanthropy and Inside Philanthropy's "Philanthropist of the Year".

In September 2003, Allen launched the Allen Institute for Brain Science with a $100 million contribution dedicated to understanding how the human brain works. Allen eventually donated $500 million to the institute, making it his single-largest philanthropic recipient. The institute has taken a Big Science and open science approach; it makes research tools available to the scientific community. The institute's projects include the Allen Mouse Brain Atlas, Allen Human Brain Atlas and the Allen Mouse Brain Connectivity Atlas. It helped to advance and shape the White House's BRAIN Initiative and the Human Brain Project.

Founded in 2014, the Allen Institute for Artificial Intelligence (AI2)'s main focus is to research and engineer artificial intelligence. The institute is modeled after the Allen Institute for Brain Science and led by researcher and professor Oren Etzioni. As of 2015, AI2 had undertaken four main projects, Semantic Scholar, Euclid, Plato, and Aristo—the latter of which aims to build an AI system that can pass an 8th-grade science exam.

In December 2014, Allen committed $100 million to create the Allen Institute for Cell Science in Seattle. As of 2014, the institute was investigating and creating a virtual model of cells in the hope of finding treatments for diseases. Like Allen's other institutes, all data generated and tools developed will be made publicly available online.

While Allen expressed interest in romantic love and one day having a family, he never married and had no children. His marriage plans with his first girlfriend were cancelled as he felt he "was not ready to marry at 23". He was sometimes considered reclusive. In the 1990s, he purchased Rock Hudson's Los Angeles estate from film director John Landis and added the Neptune Valley recording studio to the property. Allen's family put the home on the market for $56 million after his death.

Allen received his first electric guitar at the age of sixteen, and was inspired to play it by listening to Jimi Hendrix. In 2000, Allen played rhythm guitar on the independently produced album Grown Men. In 2013, he had a major label release on Sony's Legacy Recordings: Everywhere at Once by Paul Allen and the Underthinkers. PopMatters.com described Everywhere at Once as "a quality release of blues-rock that's enjoyable from start to finish".

In 2011, Allen's memoir, Idea Man: A Memoir by the Co-founder of Microsoft, was published by Portfolio, a Penguin Group imprint. The book recounts how Allen became enamored with computers and, at an early age, conceived the idea for Microsoft, recruited his friend Bill Gates to join him, and launched what would become the world's most successful software company. It also explores Allen's business and creative ventures following his 1983 departure from Microsoft, including his involvement in SpaceShipOne, his purchase of the Portland Trail Blazers and Seattle Seahawks, his passion for music, and his ongoing support for scientific research. The book made the New York Times Best Seller list. A paperback version, which included a new epilogue, was published on October 30, 2012.

Allen was diagnosed with Stage 1-A Hodgkin's lymphoma in 1982. His cancer was successfully treated by several months of radiation therapy. Allen was diagnosed with non-Hodgkin lymphoma in 2009. Likewise, the cancer was successfully treated until it returned in 2018. It ultimately caused his death by septic shock on October 15, 2018. He was 65 years old.

Allen's sister, Jody Allen, was named executor and trustee of his estate.

Several Seattle-area landmarks, including the Space Needle, Columbia Center and Lumen Field, as well as various Microsoft offices throughout the United States, were illuminated in blue on November 3, 2018, as a tribute to Allen. He was also honored by his early business partner and lifelong friend Bill Gates, who said in a statement:

Paul loved life and those around him, and we all cherished him in return. He deserved much more time, but his contributions to the world of technology and philanthropy will live on for generations to come. We will miss him tremendously.
