I looked back at Lincoln Park in the early years, and our curatorial staff were people that were fortunate to go to college. The great majority of them graduated with a zoology degree, and that was considered an entry ticket to a zoo staff, a curatorial position. In those days, we even had more than one self-made person, man. Marlin, I mentioned never had an academic background, the man who built and ran the Detroit Zoo is a landscape architect. So that it wasn’t just a case of doing, knowing animal graduate studies. But I think that gradually is that changed and in today’s world, the academia portion, nowadays animal keepers are not only just nice people and care about animals. I’d say a great number of them have already some degree in biology. Most of the staffs today have either masters or doctorates in some area of biology.
