Banco Nacional was a bank from Brazil. It was taken over by Unibanco in 1995.

The Nacional brand is better known as main sponsor of Ayrton Senna during most of his racing career in Formula One (1985-1994).

The TV Globo's popular news program "Jornal Nacional" was originally named after the name of the bank with respect to the main sponsor.

Alfredo González Flores served as President of Costa Rica from 1914 to 1917. He was unable to complete his presidential mandate following a coup d'état on 27 January 1917, led by Federico Tinoco, his secretary for War and the Navy.

Alfredo González was born in Heredia, Costa Rica on 15 July 1877 as the son of Domingo González Pérez and Elemberta Flores. González graduated from the Grammar school of Costa Rica in 1896 and earned the title of lawyer in 1903.

He was called to the Presidency on 8 May 1914 by the Congress, resulting from a pact between the two political groups with greater number of votes: the Republican Party and the Duranista party, when none of the three competing parties managed to secure an absolute majority.

During his administration, he founded the Normal School of Heredia in 1915 and the International Bank of Costa Rica (today the National Bank). It created the Meetings of Agricultural Credit, that led to the resurgence of economic, commercial, and industrial activity of the country. He established the General Depots of Deposit, the system of Direct Tributación and the Law of the Tax of Charity. He governed during World War I, which brought serious consequences for the financial situation of the government and the country in general. When the banks refusing to facilitate credit to him, he created the Bank the International with the ability to emit currency. From that moment, the State entered to compete with the private bank.

Ayrton Senna da Silva (pronounced [aˈiɾtõ ˈsenɐ da ˈsiwvɐ] ( listen); 21 March 1960 – 1 May 1994) was a Brazilian racing driver. Senna was a three-time Formula One world champion and is widely regarded as one of the greatest F1 drivers of all time. He died in a crash at Tamburello corner while leading the 1994 San Marino Grand Prix and is the most recent driver to die at the wheel of a Formula One car.

Senna began his motorsport career in karting, moving up to open-wheel racing in 1981, and winning the British Formula 3 championship in 1983. He made his Formula One debut with Toleman-Hart in 1984 before moving to Lotus-Renault the following year and winning six Grands Prix over the next three seasons. In 1988, he joined Frenchman Alain Prost at McLaren-Honda. Between them, they won all but one of the 16 Grands Prix that year and Senna his first World Championship. Prost claimed the championship in 1989, and Senna his second and third championships in 1990 and 1991. In 1992, the Williams-Renault combination began to dominate Formula One. Senna nonetheless managed to finish the 1993 season as runner-up, winning five races and negotiating a move to Williams in 1994.
