Los Angeles, California (CNN) -- Actor Pernell Roberts, who played the eldest Cartwright brother in TV's "Bonanza," died at his Malibu, California, home Sunday at 81, his lawyer said.
Younger TV viewers may remember Roberts from the lead role in "Trapper John, M.D.," a medical drama that aired on CBS for seven years, ending in 1986.
Roberts, a native of Waycross, Georgia, spent much of his adult life "pursuing his dream of equality for all," according to a family statement released by his lawyer, Richard Stone.
Roberts spent the first decade of his acting career on stage -- including Broadway -- before he moved to Hollywood to act in movies.
R.I.P., Mr. Roberts.
