BSD, the operating system many claim to be the actual world’s first open source operating system.
Initially called Berkeley Unix, as it was based on the source code of the original Unix developed at Bell Labs, BSD, or Berkeley Software Distribution, is a now discontinued operating system developed and distributed by the Computer Systems Research Group at the University of California, Berkeley by a team led by Bill Joy in the 1970s.

And to understand BSD, you must understand these early days of Unix. In that, although it was proprietary, the earliest distributions of Unix included the source code, allowing researchers at universities to modify and extend Unix. The operating system arrived at Berkeley in 1974, at the request of computer science professor Bob Fabry, a Symposium on Operating Systems Principles committee member, where Unix was first presented. BSD came to life as a variant of Unix in the late 1970s by a team of programmers at UC Berkeley.
At first, BSD was not a clone of Unix, or even a substantially different version of it. It just included some extra features, which were intertwined with code owned by AT&T...
