gorillas, which had been little studied up to that time. As well as trailing and photographing the animals, the expedition shot and killed five for recovery and preservation as museum exhibits. Some of the gorilla meat was eaten by members of the expedition. Akeley recalled that when Bradley shot one large and placid male that "it took all one's scientific ardour to keep from feeling like a murderer" and Mary, discussing the same event, noted she would "never forget the humanness of that black, upturned face". She later campaigned for gorillas to be protected from game hunters and for protective reservations to be established. During the expedition Bradley and Alice became ill, and a series of blood transfusions from Mary were required to save their lives. The expedition returned to the United States in 1922, and Bradley spent the following two years in convalescence. Mary wrote On the Gorilla Trail in 1922 about the expedition. Later life Bradley and his family undertook a second expedition to the Congo in 1924, which was the first to move through the country west of Lake Edward; Mary published Caravans and Cannibals in 1926 about this trip. A third expedition of 1930–31 studied the African Pygmies and Mangbetu people. Bradley traveled along in 1935 to Sumatra and Indochina to hunt tigers. Bradley was involved with Chicago's Brookfield Zoo and in 1933 became chair of their animal committee, tasked with gathering animals for the collection. He later became a vice president of the zoo, though he resigned in 1951 to embark upon an animal-collecting expedition to Africa. Bradley had aimed to bring okapis to the zoo since 1939 and achieved his aim in 1955. He died in Chicago on April 22, 1961.
