Massa (1930 – 30 December 1984) was a male lowland gorilla who reached the age of 54 years.
He was shipped to the United States at an early age and his first owner was Brooklyn eccentric Gertrude Lintz.
In 1935, after accidentally spilling water on Massa, which startled him and prompted him to attack, Lintz sold him to the Philadelphia Zoo.
Massa lived at the zoo until his death from a stroke on 30 December 1984, following a special birthday party held by the zoo, complete with a special cake and a live dixieland band.
The 1997 film Buddy was based on the life of Massa (with some elements from the life of another of Lintz's gorillas, Gargantua, who was known at the time as Buddy).
