He was an American biologist
His name is Roger Payne and he is an American biologist who has studied them for 50 years.
It was the 60’s, there was a lot of whale hunting because people were afraid of them and because this left a lot of money. Dr. Payne was desperately looking for people to know more about these wonderful creatures and change their perception of them.
In collaboration with an acoustic engineer, Roger Payne managed to record the song of the whales, they found five different types !, all this later became an album that went around the world.
The disc included a brochure that explained the danger in which the whales were. This helped people start taking care of them!
Then Dr. Payne founded an organization for the defense and conservation of whales.
