(Newser) – Dennis Ritchie, who invented the C programming language and helped create the UNIX operating system, died last weekend at age 70. His death after a long illness was first reported by Google engineer Rob Pike. Obituaries popping up on tech sites hail his work, vision, and legacy:

  • “Ritchie's contribution to computer science cannot be overstated. … His vision, innovation, and hard work shaped much of what has come in the following four decades,” writes Lawrence Latif on the Inquirer. “To this day C is arguably the fastest, most efficient, most widely deployed high level programming language."

  • The birth of C is perhaps not as well known as other legendary moments in the history of computing, but it “has as much claim, if not more, to be the true seminal moment of IT as we know it,” writes Rupert Goodwins in an extensive post on ZDNet. Ritchie was focused on “making software that satisfied the intellect while freeing programmers to create their dreams."
  • “C remains the second most popular programming language in the world … and ushered in C++ and Java; while … UNIX led to, among other things, Linus Torvalds’ Linux,” writes Rip Empson on TechCrunch. “The work has without a doubt made Ritchie one of the most important, if not under-recognized, engineers of the modern era."
