Found through the Feminatronic blog: some articles, videos etc. on  Louis and Bebe Barron, two American electronic music composers  who made the score for the classic sci-fi movie Forbidden Planet in the 1950’s:

The Barrons didn’t get the credits as music composers of the score of this classic movie, however. This article on the NPR Music website from 2005 explains why and how they became “forgotten pioneers” of electronic music. But all was not lost: Louis and Bebe Barron continued to compose electronic music up until the turn of the century and thus were not completely forgotten. They now even have their own Wikipedia article, which saves their work for future generations…
