Zoo Frankfurt

This guide to Zoo Frankfurt starts with the no-feeding signs posted around the grounds and asks why they matter so much here. It traces complaints about visitors overfeeding the animals back to the zoo's first week in 1858, past the red feeding puzzles keepers built for the monkey house in 1925, and forward to veterinarian Bernhard Grzimek, who rebuilt the zoo from the rubble of 1945 and later took a stand after a newly arrived elephant in 1953.
