Stan Brock, provider of mobile medical clinics

ROCKFORD, Tenn. (AP) — Stan Brock, the founder of an organization that uses mobile medical clinics to bring health care services to people in remote, underserved areas of the U.S. and around the world, has died in Tennessee. He was 82.

Remote Area Medical said in a news release that Brock died Wednesday. RAM spokesman Robert Lambert told the Associated Press that Brock had been active until he suffered an illness a few weeks ago. Brock died peacefully at home in Rockford, Tennessee, he said.

Brock started the first RAM clinic in the U.S. in May 1992 in Sneedville, Tennessee.

The organization was initially founded to provide free medical care in Guyana and other developing countries, the news release said. It still operates an air ambulance program in Guyana.

RAM also responds to natural disasters, such as Hurricane Maria in Puerto Rico last year, Hurricane Matthew in Haiti in 2016 and the Nepal earthquakes in 2015.

Brock was born in Preston, Lancashire, England, in 1936. He moved to the former British Guiana — which is now Guyana — in 1952 to become a cowboy, cattle ranch operator and aircraft pilot.

Brock came to the U.S. in 1968 and gained fame by appearing on NBC’s “Mutual of Omaha’s Wild Kingdom,” alongside Marlin Perkins. Brock also appeared in films including “Escape from Angola,” released in 1976, and “Galyon: The Indestructible Man,” from 1980.
