Richard O'Barry is an ex-U.S. Navy diver who in the 1960s helped catch dolphins for marine parks. He even trained the dolphins who played "Flipper" in the TV series of the same name. Later, though, he began working to undo his work by lobbying to free dolphins kept in captivity.
He even helped free a dolphin named Flipper in Brazil in the '90s (not one of the original Flippers, as some reports state).
Mr. Barry, if you read this, please drop me a line. I have some free Mellow Monk green tea for you!
