This maze of electronic circuits, wires, knobs and keyboards was invented by a man named Robert Arthur Moog and developed as a musical instrument with the help of some interested composers: One of them was Wendy Carlos, whose "Switched On Bach" album put the Moog on the map, and started many people taking electronic music seriously. The original theme was created by Wisconsin composer Don Voegeli on a tiny Putney synthesizer, but, in 1974, when Voegeli was asked to create a new, updated ATC theme, he used a brand-new Moog synthesizer he had just purchased for his Madison studio, which was installed by Robert Moog himself and took up an entire room. For almost 10 years, Voegeli's Moog synthesizer version of the ATC theme was heard week-in, week-out on public radio, until in 1983 the by-then very familiar electronic theme was arranged for live studio musicians.You can sample all of the theme's many iterations at WTMU's "Beware of the Blog," including an arrangement for saxophone quartet. Kind of nerdy, but fun. This page on the show's 30th anniversary has a lot of tidbits ... and a quiz!
