As part of our late 1950s vocabulary, we well knew the Ponderosa, Little Joe, Hoss, Ben Cartwright,etc. on that great show "Bonanza."It came Saturday night and everyone was glued to the television set. This was a real show depicting family values. There may have been a weekly crisis, but it was the strong family atmosphere that pulled everyone together.Lorne Greene was dominant as the patriarch of the family. His words depicted wisdom. We often were left to wonder that Ben Cartwright, a widower, must have been the best of husbands to that poor wife of his who had died. He reared wonderful sons.Naturally, we all wondered why Pernell Roberts left the show. The show was a gold mine and Roberts surrendered loads of money when he departed. His career never took off as he was associated as a Cartwright son. He should have tried to get back into the series. He certainly lost a bonanza by dropping out.
