José Francisco de San Martín (c. 1778 – 17 August 1850), known simply as José de San Martín (Spanish pronunciation: [xoˈse ðe sam marˈtin]), was an Argentine general and the prime leader of the southern part of South America's successful struggle for independence from the Spanish Empire.

Born in Yapeyú, Corrientes, in modern Argentina, he left his mother country at the early age of seven and studied in Málaga, Spain.

In 1808, after joining Spanish forces in the Peninsular War against the French, San Martín started making contact with South American supporters of independence from Spain. In 1812, he set sail for Buenos Aires from England and offered his services to the United Provinces of South America, present-day Argentina. After the Battle of San Lorenzo of 1813, and some time on command of the Army of the North (Spanish: Ejército del Norte) during 1814, he began to put into action his plan to defeat the Spanish forces that menaced the United Provinces from Upper Peru, making use of an alternative path to the Viceroyalty of Peru. This objective first involved the establishment of a new army, the Army of the Andes, in Cuyo Province, Argentina. From there, he led the Crossing of the Andes to Chile, and prevailed over the Spanish forces at the Battle of Chacabuco and the Battle of Maipú (1818), thus liberating Chile from royalist rule. Then he set sail to attack the Spanish stronghold of Lima, Peru, by sea.

Los Cinco (in English: "The Five") is an unofficial collective of Latin American composers living and working in Los Angeles. These composers include: Daniel Catán, Miguel del Águila, Aurelio de la Vega, Enrique González-Medina, and Carlos Rodríquez.

Meant to draw a comparison between this collective and a group of avant-garde Parisian composers active in the 1920s known as "Les Six", the term "Los Cinco" was originally coined by Sean Bradley, an American conductor. Bradley first presented these composers as a collective in public performance, and the label Los Cinco first appeared in print in a Los Angeles Times review dated August 3, 2004.

The music by these composers shares "...certain common features, including a vibrancy of ideas, no fear of sensuality or humor, and an infectious passion." (Josef Woodward, Los Angeles Times)

Carlos Calderón de la Barca (born 2 October 1934) is a Mexican football forward who played for Mexico in the 1958 FIFA World Cup. He also played for Atlante.
