Linus Benedict Torvalds (//; Swedish: [ˈliːn.ɵs ˈtuːr.valds] (13px listen); born December 28, 1969) is a Finnish American software engineer, who was the principal force behind the development of the Linux kernel that became the most popular kernel for operating systems. He later became the chief architect of the Linux kernel and now acts as the project's coordinator. He also created the distributed revision control system git. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award.

Torvalds was born in Helsinki, Finland. He is the son of journalists Anna and Nils Torvalds, and the grandson of statistician Leo Törnqvist and of poet Ole Torvalds. Both of his parents were campus radicals at the University of Helsinki in the 1960s. His family belongs to the Swedish-speaking minority. Torvalds was named after Linus Pauling, the Nobel Prize–winning American chemist, although in the book Rebel Code: Linux and the Open Source Revolution, Torvalds is quoted as saying, "I think I was named equally for Linus the Peanuts cartoon character", noting that this makes him half "Nobel Prize–winning chemist" and half "blanket-carrying cartoon character".
Torvalds attended the University of Helsinki between 1988 and 1996, graduating with a master's degree in computer science from NODES research group. His academic career was interrupted after his first year of study when he joined the Finnish Army Uusimaa brigade, in the summer of 1989, selecting the 11-month officer training program to fulfill the mandatory military service of Finland. In the army he held the rank of second lieutenant, with the role of a ballistic calculation officer. Torvalds bought computer science professor Andrew Tanenbaum's book Operating Systems: Design and Implementation, in which Tanenbaum describes MINIX, an educational stripped-down version of Unix. The book changed Torvalds life: he was fascinated by the clear structure of the Unix and its underlying philosophy. In 1990, he resumed his university studies, and was exposed to UNIX for the first time, in the form of a DEC MicroVAX running ULTRIX. His M.Sc. thesis was titled Linux: A Portable Operating System.
His interest in computers began with a Commodore VIC-20, at the age of 11 in 1981, initially programming in BASIC – and later in assembly language. After the VIC-20 he purchased a Sinclair QL, which he modified extensively, especially its operating system. "Because it was so hard to get software for it in Finland, Linus wrote his own assembler and editor (in addition to Pac-Man graphics libraries)" for the QL, as well as a few games. He is known to have written a Pac-Man clone named Cool Man. On January 5, 1991 he purchased an Intel 80386-based clone of IBM PC before receiving his MINIX copy, which in turn enabled him to begin work on Linux. The first prototypes of Linux were publicly released later that year. Version 1.0 was released on March 14, 1994.
Torvalds first encountered the GNU Project in 1991, after another Swedish computer science student Lars Wirzenius took him to the University of Technology to listen to free software-guru Richard Stallman's speech. Torvalds used Stallman's General Public License version 2 (GPLv2) for his Linux kernel, that is his preferred license (also later used in his revision control system git as well as the diving log software Subsurface) and wrote its (first version) source code (but compiled with Stallman's GNU Compiler Collection (GCC) compiler) from scratch (and has not upgraded to GPLv3).
After a visit to Transmeta in late 1996, Torvalds accepted a position at the company in California, where he would work from February 1997 until June 2003. He then moved to the Open Source Development Labs, which has since merged with the Free Standards Group to become the Linux Foundation, under whose auspices he continues to work. In June 2004, Torvalds and his family moved to Dunthorpe, Oregon, to be closer to the OSDL's Beaverton, Oregon–based headquarters.
From 1997 to 1999, he was involved in 86open helping to choose the standard binary format for Linux and Unix. In 1999 he was named by the MIT Technology Review TR100 as one of the world's top 100 innovators under age 35.
In 1999, Red Hat and VA Linux, both leading developers of Linux-based software, presented Torvalds with stock options in gratitude for his creation. That same year both companies went public and Torvalds's share value temporarily shot up to roughly $20 million.
Although Torvalds believes "open source is the only right way to do software", he also has said that he uses the "best tool for the job", even if that includes proprietary software. He was criticized for his use and alleged advocacy of the proprietary BitKeeper software for version control in the Linux kernel. Torvalds subsequently wrote a free-software replacement for BitKeeper called git.
In 2008, Torvalds stated that he used the Fedora distribution of Linux because it had fairly good support for the PowerPC processor architecture, which he had favoured at the time. His usage of Fedora was confirmed in a later 2012 interview.
The Linus/Linux connection
Initially, Torvalds wanted to call the kernel he developed Freax (a combination of "free", "freak", and the letter X to indicate that it is a Unix-like system), but his friend Ari Lemmke, who administered the FTP server where the kernel was first hosted for download, named Torvalds's directory linux.
Authority and trademark
As of 2006, approximately two percent of the Linux kernel was written by Torvalds himself. Because thousands have contributed to the Linux kernel, this percentage is one of the largest contributions to it. However, he stated in 2012 that his own personal contribution is mostly merging code written by others, with little programming. Torvalds retains the highest authority to decide which new code is incorporated into the standard Linux kernel.
Linus Torvalds is married to Tove Torvalds (née Monni)—a six-time Finnish national karate champion—whom he first met in the autumn of 1993. Linus was running introductory computer laboratory exercises for students and instructed the course attendees to send him an e-mail as a test, to which Tove responded with an e-mail asking for a date. Tove and Linus were later married and have three daughters, Patricia Miranda (born 1996), Daniela Yolanda (born 1998), and Celeste Amanda (born 2000), two of whom were born in the United States. The Linux kernel's reboot system call accepts their dates of birth (written in hexadecimal) as magic values.
Torvalds describes himself as "completely a-religious—atheist", adding that "I find that people seem to think religion brings morals and appreciation of nature. I actually think it detracts from both. It gives people the excuse to say, 'Oh, nature was just created,' and so the act of creation is seen to be something miraculous. I appreciate the fact that, 'Wow, it's incredible that something like this could have happened in the first place.'" He later added that while in Europe religion is mostly a personal issue, in America it has become very politicized. When discussing the issue of church and state separation, Torvalds also said, "Yeah, it's kind of ironic that in many European countries, there is actually a kind of legal binding between the state and the state religion."
In 2010, Torvalds became a United States citizen and registered to vote in the United States. He is unaffiliated with any U.S. political party, saying, "I have way too much personal pride to want to be associated with any of them, quite frankly."
IEEE Computer Pioneer Award
On April 23, 2014, the Institute of Electrical and Electronics Engineers named Torvalds as the 2014 recipient of the IEEE Computer Society's Computer Pioneer Award. The Computer Pioneer Award was established in 1981 by the IEEE Computer Society Board of Governors to recognize and honor the vision of those whose efforts resulted in the creation and continued vitality of the computer industry. The award is presented to outstanding individuals whose main contribution to the concepts and development of the computer field was made at least 15 years earlier.
Internet Hall of Fame
On April 23, 2012, at Internet Society's Global INET conference in Geneva, Switzerland, Torvalds was one of the inaugural inductees into the Internet Hall of Fame, one of ten in the Innovators category and thirty-three overall inductees.
Millennium Technology Prize
On April 20, 2012, Torvalds was declared one of two winners of that year's Millennium Technology Prize, along with Shinya Yamanaka. The honor is widely described as technology's equivalent of the Nobel Prize.
In 1997, Torvalds received his Master degree (Laudatur Grade) from the Department of Computer Science at the University of Helsinki. Two years later he received honorary doctor status at Stockholm University, and in 2000 he received the same honor from his alma mater. University of Helsinki has named an auditorium after Torvalds and his computer is on display at the Department of Computer Science.
In 1998, Torvalds received an EFF Pioneer Award. In 2000 he was awarded the Lovelace Medal from the British Computer Society. In 2001, he shared the Takeda Award for Social/Economic Well-Being with Richard Stallman and Ken Sakamura. In 2008, he was inducted into the Hall of Fellows of the Computer History Museum in Mountain View, California, "for the creation of the Linux kernel and the management of open source development of the widely used Linux operating system." He was awarded the C&C Prize by the NEC Corporation in 2010 for "contributions to the advancement of the information technology industry, education, research, and the improvement of our lives".
Time magazine has recognized Torvalds multiple times:
- In 2000, he was 17th in their Time 100: The Most Important People of the Century Poll.
- In 2004, he was named one of the most influential people in the world.
- In 2006, the magazine's Europe edition named him one of the revolutionary heroes of the past 60 years.
InfoWorld presented him with the 2000 Award for Industry Achievement. In 2005 Torvalds appeared as one of "the best managers" in a survey by BusinessWeek. In 2006, Business 2.0 magazine named him one of "10 people who don't matter" because the growth of Linux has shrunk Torvalds's individual impact.
In summer 2004, viewers of YLE (the Finnish Broadcasting Company) placed Torvalds 16th in the network's 100 Greatest Finns. In 2010, as part of a series called The Britannica Guide to the World's Most Influential People, Torvalds was listed among The 100 Most Influential Inventors of All Time (ISBN 9781615300037).
As of March 2011, Torvalds has been granted 35 patents worldwide (application and granted patents).
Desktop environment criticism
In 2005, on the official GNOME developmental mailing lists, Torvalds encouraged users to switch to K Desktop Environment 3 rather than use GNOME. However, Torvalds thought KDE Plasma Desktop 4.0 was a "disaster" because of its lack of maturity, and so he had switched to GNOME by 2009. Dissatisfied with his perceived loss of productivity, he switched to Xfce after the GNOME 3 release, making another harsh post against GNOME. After improved KDE versions were made, he switched back to KDE Plasma Desktop 4 but soon switched back to GNOME 3 stating that "it has been getting less painful" with Frippery and gnome-tweak-tool which he suggested to be merged into GNOME.
Possible NSA approachIn September 2013, Torvalds was asked at the LinuxCon conference whether he had been approached by a US government agency to add backdoors into Linux; he responded with a verbal "no" while nodding his head "yes". He later stated that it was obviously a joke. However, Linus's father Nils states:
When my oldest son [Linus Torvalds] was asked the same question: “Has he been approached by the NSA about backdoors?” he said “No”, but at the same time he nodded. Then he was sort of in the legal free. He had given the right answer, [but] everybody understood that the NSA had approached him.

A sort of anti-celebrity, he is plainly ambivalent about fame and content to stay nestled at home in a tony cluster of million-dollar houses atop the densely forested hills of the Dunthorpe neighborhood.
