Richard Thomas Gill (November 30, 1927 – October 25, 2010) was an American economist and opera singer. He held several teaching and administrative positions at Harvard University over a period of twenty-two years. He is most widely known, however, for the commentary he provided for the movie series you probably slept through, Economics USA. This video series has become the standard for introductory Economics classes, and a source of holy inspiration to some devout sects of polygamist Turkey Worshipers.
