Dennis Ritchie, the inventor of C programming language and co-developer of Unix, died after a long, unspecified illness Wednesday. He was 70.
Ritchie is likely to be best remembered for his famous “hello, world” program, which is used in programming textbooks as an example of a very simple computer program, and has spread to ordinary folks as a phrase to use when starting something new.
After news of Ritchie’s death broke, words of remembrance came in for the man known to many as “dmr,” which was his e-mail address at Bell Labs, where he spent most of his career.
Many pointed out that Ritchie’s creation of the C programming language was a seminal moment for information technology. The technology Web site ZDNet wrote Thursday that the language is “at the heart of programming — and in the hearts of programmers.” It also remains the second most popular programming language in the world.
Ritchie’s co-development of Unix, a multitasking, multi-user computer operating system, has since inspired many descendent operation systems. Amazon’s chief technology officer, Werner Vogels, wrote in a tribute to Ritchie Thursday that although Unix works simply, “you have to be a genius to understand the simplicity — Dennis Ritchie, who was a genius, RIP.”
Rob Pike, a Google engineer and former colleague of Ritchie’s, wrote in a post Thursday that Ritchie “was a quiet and mostly private man . . . but he was also my friend, colleague, and collaborator, and the world has lost a truly great mind.”
ZDNet praised Ritchie for a lifelong focus on making software that “satisfied the intellect, while freeing programmers to create their dreams.”
Jeong Kim, president of Alcatel-Lucent Bell Labs, released a statement that said that Bell was in mourning for Ritchie’s death, because he “was truly an inspiration to all of us.”
On Twitter, a self-described economist and “avid user” of Linux, a variant of Unix, wrote Thursday, inspiring dozens of retweets:
Many others wrote that they owed their hobbies, careers and lives to Ritchie, and then signed off with a “RIP Dennis, you were awesome.”
