Linus Benedict Torvalds (/ˈliːnəs ˈtɔːrvɔːldz/ LEE-nəs TOR-vawldz, Finland Swedish: (listen); born 28 December 1969) is a Finnish-American software engineer who is the creator and, historically, the principal developer of the Linux kernel, which is the kernel for Linux operating systems (distributions) and other operating systems such as Android and Chrome OS. He also created the distributed version control system Git and the scuba dive logging and planning software Subsurface.
He was honoured, 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 and the 2018 IEEE Masaru Ibuka Consumer Electronics Award.
Torvalds was born in Helsinki, Finland, on 28 December 1969. He is the son of journalists Anna and Nils Torvalds, and the grandson of statistician Leo Törnqvist and of poet Ole Torvalds. His parents were campus radicals at the University of Helsinki in the 1960s. His family belongs to the Swedish-speaking minority in Finland. 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".
