Harmony Gold
Harmony Gold is an American production/distribution company that is most famous for creating Robotech from three unrelated anime series. It was the company where Carl Macek got his start, working on Robotech before co-founding Streamline Pictures which produced many more anime dubs.
The company has released quite a bit of material with no connection to anime, but among fandom, especially early anime fandom, the name has become almost synonymous with Robotech. It still occasionally releases Robotech-related material, as recently as Robotech: The Shadow Chronicles in 2007. It also produced Windaria, Captain Harlock and the Queen of a Thousand Years (a TV series which edited together Captain Harlock and Queen Millennia), also under Macek, and some early pilot dubs for Dragon Ball, the Lensman anime, Minky Momo, and Space Adventure Cobra.
