From Wikipedia:
Gentle Ben ran on CBS from September 10, 1967 until August 31, 1969, airing a total of 56 episodes. The show stars a young Clint Howard (Ron Howard's brother) as Mark Wedloe and chronicles his adventures with a lovable 650-pound American black bear, Ben (played by Bruno the Bear).
Musician and voice actor Candy Candido provided the voice of Ben. Dennis Weaver played Mark's father, park ranger Tom Wedloe. Beth Brickell had the role of his mother, Ellen. The series was produced by Ivan Tors, also the creator of Lloyd Bridges's Sea Hunt. The series also changed the locale from the book's Alaska to Florida.
Although the bear character in a subsequent television series, The Life and Times of Grizzly Adams, is also named Ben, there is no connection between the bears.
