In the early ’60s which would’ve been about ’64, Marlin called me up to his office and he said, “I want you to build up a slide. When you give your lectures, you should be able to have a slide collection to enhance your lectures. So I want you to go around the zoo and take pictures of animals, the animals that you can’t bring to the classroom. Here is a Pentax camera. This is my favorite camera. And I want you to go out and take a roll of pictures and then bring ’em back and I’ll critique ’em for you.” And I said, “Okay.” He said, “You can start. You can take my picture right here.” So I took his picture. He’s there at his desk with zebra skin on the back.
