Linus Torvalds is a Finnish-born American software engineer most notably known for creating the Linux kernel, a core system code used in many operating system distributions in use today. He remains the principal developer of Linux, managing tens of thousands of developers that contribute code for functions and bug fixes for the kernel. He also created GIT, a distribution control system widely used by development teams across the globe.
Linus Torvalds was born in Helsinki, Finland in 1969 and was named after the American Nobel Prize-winning chemist, Linus Pauling. He became interested with computing in 1981 at age 11 when he began programming in a Commodore VIC-20 system, initially using BASIC and then assembly language. He then moved on to a Sinclair QL, which he extensively modified, especially the operating system, and wrote his own assembler, editor and games for it since software for it was hard to come by in Finland.
Torvalds attended the University of Helsinki between 1988 and 1996, where he graduated with a master's degree in computer science from the NODES research group. During his university years, one of his course books was Andrew Tenenbaum's book "Operating Systems: Design and Implementation," where he was introduced to MINIX, which was a stripped-down version of Unix that led him to a fascination with Unix's clear structure and underlying philosophy.
In January 1991, Torvalds purchased an Intel 80386-based IBM PC clone and then later received his copy of MINIX. The new processor and MINIX started him on the path of coding his own drivers, such as disk drivers, serial drivers and a file system, as well as different OS processes because he needed them in order to participate in news groups to learn more about the POSIX standard. By doing these things, he had already unwittingly created Linux, but it was not until Ari Lemmke, his friend who administered the FTP servers gave him a directory called "linux" that the name was coined. He eventually wrote his Master's thesis titled "Linux: A Portable Operating System." Torvalds officially announced the OS in the MINIX Usenet newsgroup "comp.os.minx" on August 25, 1991.
The Opens Source Development Lab (OSDL) was established in 2000, which later merged with the Free Standards Group to form The Linux Foundation. Linus Torvalds is still an active contributor and moderator of the Linux kernel under the foundation and manages contributions from thousands of developers.
