PYGMY HIPPOPOTAMUSES 
Because the National Zoological Park had considerable success in 
raising pygmy hippopotamuses, it seems advisable to list the breeding 
record here. The first pygmy hippopotamus to come to the Zoo was 
a gift from Harvey Firestone, Sr., to President Calvin Coolidge in 
1927. It was known as Billy. In 1929 a mate, Hannah, was pur- 
chased. In 1940 the Smithsonian Institution-Firestone Expedition 
returned from Liberia with one young male, which died May 3, 1943, 
and one adult female (known as Matilda).
