Nicanor Zabaleta (January 7, 1907 – March 31, 1993) was a Spanish virtuoso and populariser of the harp.

Zabaleta was born in San Sebastián, Spain, on January 7, 1907. In 1914 his father, an amateur musician, bought him a harp in an antique shop. He soon began taking lessons from Vincenta Tormo de Calvo (Madrid Conservatory faculty) and Luisa Menarguez. In 1925 he began studies in Paris, where his teachers were Marcel Tournier and Jacqueline Borot. In 1926, in Paris, he made his own official concert debut. Then he travelled to the U.S. and there, on July 5, 1934 he made his North America debut in New York City. At a concert in Puerto Rico in 1950 he met Graziela and they were married in 1952. They relocated to Spain and Zabaleta began touring Europe. During the years of 1959–1962 he led a harp class on Accademia Musicale Chigiana courses in Siena.

He performed mainly music of the 18th century, and also ancient and modern music. People who composed for him include Alberto Ginastera, Darius Milhaud, Heitor Villa-Lobos, Walter Piston, Ernst Krenek, Joaquín Rodrigo.Josef Tal's Concerto for Harp and Electronics was commissioned by Zabaleta in 1971, and premiered by him in Munich the same year. It is estimated that Zabaleta sold nearly three million records.

Félix Édouard Justin Émile Borel (7 January 1871 – 3 February 1956) was a French mathematician and politician.

Borel was born in Saint-Affrique, Aveyron. Along with René-Louis Baire and Henri Lebesgue, he was among the pioneers of measure theory and its application to probability theory. The concept of a Borel set is named in his honor. One of his books on probability introduced the amusing thought experiment that entered popular culture under the name infinite monkey theorem or the like. He also published a series of papers (1921-27) that first defined games of strategy.

In 1913 and 1914 he bridged the gap between hyperbolic geometry and special relativity with expository work.

In the 1920s, 1930s, and 1940s he was active in politics. In 1922 he founded ISUP, the oldest French school for Statistics. From 1924 to 1936, he was a member of the French National Assembly. In 1925, he was Minister of Marine in the cabinet of fellow mathematician Paul Painlevé. During the Second World War he was a member of the French Resistance.
