Heini Hediger (1908–1992)

You might think by the image on this book cover, that it's about how animals suffer in captivity, but it's not. It's about the biological needs of wild animals, using facts about how they exist in nature to promote husbandry methods in zoos that are better for their welfare. Such as: making sure tree-dwelling animals feel high enough off the ground to be safe, herbivores have enough flight-distance from human observers, nocturnal creatures aren't in constant daylight, etc. Down to the smallest details like what type of flooring in a cage makes the animal comfortable, what type of feeding situation suits its social needs, how to train wildlife to accept the presence of humans (so they aren't constantly in a panic) and even basic training to make their handling easier. The particulars about keeping snakes, whether or not to trim birds' wings, arguments if certain animals need a lot of space to live comfortably- were quite interesting. The author points out that most animals in the wild are not so free to roam around as we might think- they are often constrained by the microclimate, dietary needs and the pressure of conspecific rivals holding them into a strict area. He emphasizes time and time again that animals' welfare is best met by avoiding anthropomorphizing them and looking at what animals actually need, not what humans would feel better about in a certain situation. It's a book far ahead of its time- I was stunned to find it was first translated from German to English in 1950! A lot of it is rather dry, technical reading but the reasoning so clear and the snippets of case studies offered as examples so illuminating, I persevered all the way through.
