where was c originally developed and by whom
C (programming language) C was originally developed by Dennis Ritchie between 1969 and 1973 at Bell Labs,[5] and used to re-implement the Unix operating system.[6] It has since become one of the most widely used programming languages of all time,[7][8] with C compilers from various vendors available for the majority of existing computer architectures and operating systems. C has been standardized by the American National Standards Institute (ANSI) since 1989 (see ANSI C) and subsequently by the International Organization for Standardization (ISO).
Vitamin C From 1928 to 1932, Albert Szent-Györgyi and Joseph L. Svirbely's Hungarian team, and Charles Glen King's American team, identified the anti-scorbutic factor. Szent-Györgyi isolated hexuronic acid from animal adrenal glands, and suspected it to be the antiscorbutic factor.[167] In late 1931, Szent-Györgyi gave Svirbely the last of his adrenal-derived hexuronic acid with the suggestion that it might be the anti-scorbutic factor. By the spring of 1932, King's laboratory had proven this, but published the result without giving Szent-Györgyi credit for it. This led to a bitter dispute over priority.[167] In 1933, Walter Norman Haworth chemically identified the vitamin as L-hexuronic acid, proving this by synthesis in 1933.[168][169][170][171] Haworth and Szent-Györgyi proposed that L-hexuronic acid be named a-scorbic acid, and chemically L-ascorbic acid, in honor of its activity against scurvy.[171][10] The term's etymology is from Latin, "a-" meaning away, or off from, while -scorbic is from Medieval Latin scorbuticus (pertaining to scurvy), cognate with Old Norse skyrbjugr, French scorbut, Dutch scheurbuik and Low German scharbock.[172] Partly for this discovery, Szent-Györgyi was awarded the 1937 Nobel Prize in Medicine,[173] and Haworth shared that year's Nobel Prize in Chemistry.[14]
