C and UNIX are at the root of modern computing. Many of the languages we’ve covered this season are related to or at least influenced by C. But C and UNIX only happened because a few developers at Bell Labs created both as a skunkworks project. Bell Labs was a mid-twentieth century center for innovation. Jon Gertner describes it as an “idea factory.” One of their biggest projects in the 1960s was helping build a time-sharing operating system called Multics. Dr. Joy Lisi Rankin explains the hype around time-sharing at the time—it was described as potentially making computing accessible as a public utility. Large teams devoted years of effort to build Multics—and it wasn’t what they had hoped for. Bell Labs officially moved away from time-sharing in 1969. But as Andrew Tanenbaum recounts, a small team of heroes pushed on anyways. C and UNIX were the result. Little did they know how much their work would shape the course of technology.
