Felipe Birriel, also known as "El Gigante de Carolina" (Carolina's Giant) (August 16, 1916 – March 15, 1994) is considered to have been the tallest Puerto Rican, with an unconfirmed height of 2.413 meters or nearly seven feet eleven inches (Nearly 7 feet 11 inches").
Birriel, born in Carolina, Puerto Rico, was the son of Pedro and Dionisia Birriel and was the oldest of six siblings. His highest level of education was up to the second grade in elementary school. As a child, Birriel was sent to the farm fields where he helped his parents plant vegetable seeds. He also worked in the fields picking fruits and coffee beans and as a waterboy, delivered water to the sugar cane workers.
In 1932, when Birriel was 16 years old, he started to grow at an alarming rate. One day, he went to visit a doctor because he felt sick with dizzy spells and because he was also feeling weak. The doctor informed Birriel that for some unknown reason, his pituitary gland had developed a tumor. Even though the condition did not have a known cure, it was still treatable.
The treatment required a radio therapy machine which could only be found in the United States. The machine was sent in 1932, but it was not until 1941 — nine years later — that it finally arrived in Puerto Rico.
Birriel lived with his brother and sister-in-law in the town of Carolina and became something of a folk hero and known as "El Gigante de Carolina" (The Giant of Carolina). He appeared in the film Flight of the Lost Balloon filmed in Puerto Rico in 1961. In 1974, during the celebration of the FIBA World Basketball Championships celebrated in San Juan, Puerto Rico, Birriel was the guest of honor and was invited to the basketball court, in front of all the spectators he dunked the ball without jumping, a standing ovation followed.
The Government of Puerto Rico and local businessmen helped him economically, since his daily personal needs could not be met with the money that he earned in personal appearances. The owners of local furniture stores also helped Birriel by making furniture especially for him. His health, however had worsened progressively and he died from a heart attack on March 15, 1994, at the age of 77, in Carolina, Puerto Rico.
