Puerto Rico celebrates all official U.S holidays, and a number of other official holidays established by the Commonwealth government.
Additionally, many municipalities celebrate their own Patron Saint Festivals (fiestas patronales in Spanish), as well as festivals honoring cultural icons like Bomba y plena, danza, salsa, hamacas (hammocks), and popular crops such as plantains and coffee.
Dr. Jose Celso Barbosa Alcala (July 27, 1857 – September 21, 1921) was a Puerto Rican physician, sociologist and political leader. Known as the father of the Statehood for Puerto Rico movement, he was the first Puerto Rican to earn a medical degree in the United States and was among the first of African Americans to do so.
After his return to the island in 1880, Barbosa made many contributions to medicine and public health. He initiated an early form of health insurance, encouraging employers to pay a fee to cover future needs of their employees. In 1900 Barbosa was among the first five Puerto Rican leaders appointed to the Executive Cabinet under Governor Charles H. Allen, in the first civilian government organized by the United States. He served in the Cabinet until 1917. From 1917–1921, Barbosa served in the first elected Puerto Rican Senate.
