The late nineteenth and early twentieth century were a brutal time for American wildlife, with many species pushed to the brink of extinction. Yet these decades also saw the dawn of the conservationist movement. Into this contradictory era came William Temple Hornaday, a larger-than-life dynamo who uncannily embodies these conflicting threads. Gregory Dehler explores the life of Hornaday the hunter, museum builder, zoologist, author, conservationist, and anti-Bolshevist.
