Joel Sartore is a modern-day camera-toting Noah. The National Geographic photographer has a steadfast, driving: To create portraits of the world’s species before they disappear. Sartore hopes his signature Photo Ark portraits spark people to save these animals. In contrast, Carl Akeley, born a hundred years earlier, spent much of his life killing rare creatures. A Victorian taxidermist who stuffed PT Barnum’s beloved circus elephant Jumbo for posterity, he trekked through Africa searching big game to hunt for exhibits in American museums. But in the end, this experience ultimately converted him into an outspoken conservationist. Because of Akeley’s efforts to protect mountain gorillas, the first wildlife sanctuary in Africa was established in the Congo in 1925. Two photographers separated by a century, a veritable Noah and the hunter, followed contradictory paths from the other yet embraced the same goal as the driving force in their lives: Protect wildlife.
