Biography

Linus Benedict Torvalds (; Swedish: [ˈliːn.ɵs ˈtuːr.valds]; born December 28, 1969) is a Finnish-American software engineer who is the creator, and for a long time, principal developer of the Linux kernel, which became the kernel for operating systems such as the Linux operating system, Android, and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. 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.

Life and career

Early years

Torvalds was born in Helsinki, Finland in 1969. 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. 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, but later by directly accessing the 6502 CPU in machine code. He did not make use of 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.

Linux

The first prototypes of Linux were publicly released later that year (1991). Version 1.0 was released on March 14, 1994.

Torvalds first encountered the GNU Project in 1991, after another Swedish-speaking 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 GNU General Public License version 2 (GPLv2) for his Linux kernel.

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 US$20 million.

His personal mascot is a penguin nicknamed Tux, which has been widely adopted by the Linux community as the mascot of the Linux kernel.

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 favored at the time. His usage of Fedora was confirmed in a later 2012 interview. He has also posted updates about his choice of desktop environment, often in response to perceived feature regressions.

Currently, the Linux Foundation sponsors Torvalds so he can work full-time on improving Linux.

Linus Torvalds is known for disagreeing with other developers on the Linux kernel mailing list. Calling himself a "really unpleasant person", he later explained "I’d like to be a nice person and curse less and encourage people to grow rather than telling them they are idiots. I’m sorry – I tried, it’s just not in me." His attitude, which Torvalds considers necessary for making his point clear, has drawn criticism from Intel programmer Sarah Sharp and systemd developer Lennart Poettering, among others.

In 2013, at the LinuxCon conference, Torvalds was asked whether he had ever been "approached by the U.S. government to insert a backdoor into Linux". To laughter from the room, he replied "no" while nodding his head and thus implying "yes".

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 now 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.

Torvalds holds the "Linux" trademark and monitors the use of it, chiefly through the Linux Mark Institute.

Personal life

Torvalds in 2002

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."

Year Award Notes
2014 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.
2012 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.
2012 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.
2010 C&C Prize 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".
2008 Hall of Fellows 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."
2005 Vollum Award In August 2005, Torvalds received the Vollum Award from Reed College.
2001 Takeda Award In 2001, he shared the Takeda Award for Social/Economic Well-Being with Richard Stallman and Ken Sakamura.
2000 Lovelace Medal In 2000, he was awarded the Lovelace Medal from the British Computer Society.
1998 EFF Pioneer Award In 1998, Torvalds received an EFF Pioneer Award.
1997 Academic Honors In 1997, Torvalds received his master's 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.

1996 9793 Torvalds (Asteroid) In 1996, the asteroid 9793 Torvalds was named after him. In 2003, the naming of the asteroid moon Linus was motivated in part by the fact that the discoverer was an enthusiastic Linux user. Although the naming proposal referred to the mythological Linus, son of the muse Calliope and the inventor of melody and rhythm, the name was also meant to honor Linus Torvalds, and Linus van Pelt, a character in the Peanuts comic strip.
1995 Running Linux on AlphaStation In the period 1994–1999 Torvalds developed versions of Linux on early AlphaServer systems made available to him by the engineering department of Digital Equipment Corporation. Compaq software engineers developed special Linux kernel modules. Linux distributions that ran on AlphaServer systems were Red Hat 7.2. and Gentoo Linux.

Media recognition

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 by Time magazine.
  • 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).
