In 1955, a young former Marine ventured to the Belgian Congo on a month-long adventure safari to view Africa's diverse wildlife. When Arthur "Nick" Arundel boarded a commercial airliner for home, he carried a baby gorilla in each arm. Their destination was the National Zoo in Washington, D.C., known as "America's Zoo." Raising America's Zoo shares the heartbreak and triumphs of these first-generation zoo gorillas and their caregivers who worked tirelessly to make their lives better. Witness a personal story of Nick Arundel, a man who at first celebrated their capture, then grew to regret his reputation as of "gorilla hunter" and spent the rest of his life as an advocate for animal conservation.
