His father was Dr. Pedro Juan Giorgetti Battesti, an immigrant from Corsica and his mother Guadalupe Fernandez Vanga y Freites, native of Puerto Rico whose family were land owners.

Among the sugar plantations which Georgetti purchased were Los Canos in Arecibo and the Central Plata, in which he served as the corporation's president.

[3] On December 23, 1897, Georgetti was named Mayor of Barceloneta by Sabas Marin Gonzalez, the then-appointed Spanish governor of Puerto Rico.

After the United States invaded Puerto Rico and the island became a U.S. territory as a result of the Treaty of Paris of 1898, which ended the Spanish–American War, the military-appointed governor, Major General John R. Brooke, permitted, upon the advice of Luis Muñoz Rivera, that Georgetti continue as mayor.

The Union Party also favored the acquisition of greater political autonomy for Puerto Rico, as a pathway to full independence.

La Democracia also provided Rivera's son, Muñoz Marin, with an outlet to publish his written works.

Georgetti also purchased the Muñoz Rivera home in 1916 and donated it together with the Pierce Arrow car to the town of Barranquitas to be preserved as a national monument.

[6] After Muñoz Rivera's death, Barceló became the leading force behind the Union Party and its liberal ideas for the island.

Georgetti was committed to the original independentista ideals of the Union Party, and found these incompatible with an "economic partnership" with the United States, as espoused by the Alliance coalition.

Georgetti and the Fuerzas Vivas submitted a "Fiscal Memorandum" to the U.S. Secretary of War, which presented a much bleaker view of the Puerto Rican economy.

According to this memorandum, the island was on the brink of economic ruin unless it diversified its agricultural production, and become less dependent on the sugar industry as its sole source of income.

[9] Georgetti and his wife did not have any offspring, however they were the benefactors of many talented children who lacked the economic means to pursue an education.

[12] Other cities in Puerto Rico have honored his memory by naming several streets after him, including San Juan, Humacao, Comerío and Vega Alta.
