Well, the way the zoo got involved in monkey, in importing and large numbers was not the zoo per se, but the fact that so many monkeys were brought in for medical research, particularly for polio vaccines production. So in the mid ’50s, there was a big upsurge of interest in developing a polio vaccine. And by 1955, Jonas Salk vaccine had developed. His vaccine was developed to the extent that the US Department of Health approved it for human usage. So all of a sudden, for the first time, there’s a polio vaccine. Now President Roosevelt, previous to being the president had developed polio. So he and some other people founded an organization called the March of Dimes, which we know still exists. Then it was entirely devoted to polio.
