Food for the animals became difficult to obtain during the First World War, but for the most part the gardens carried on as usual. Following the declaration of peace, several monkeys originally destined for government experiments with poison gas were acquired, as was a hippo, a dromedary and a zebra. In 1921 and 1922 the zoo obtained two animals who became great favourites. Lil, an Indian elephant, arrived in 1921 accompanied by her British Malayan handler, Phil Fernandez. Phil and Lil provided entertainment, advertising, and elephant rides for 35 years. Frank, a brown bear, arrived in 1922. By the time of his death, 40 years later, he was known as the "Father of the Zoo".
