TMZ is reporting that Sherman Hemsley, who brought to life one of TV’s most important and memorable characters, has died. According to the site, the 74-year-old actor who portrayed George Jefferson on both All in the Family and The Jeffersons passed away of unknown causes at his El Paso home. As the boundary-breaking star of two wildly popular sitcoms, the man who camped it up par excellence as fearsome boss-man B.P. Richfield on Dinosaurs, and a guy who always knew how to make a delightful cameo, he will be greatly missed.
