Ricardo Castillo (October 1, 1891, Quetzaltenango — May 27, 1966, Guatemala City) was a Guatemalan composer.
Demonstrating a talent and love for music as a child, his mother sent him to France to study the subject in 1906 at the age of 14.
[1] In 1918 Castillo married the French pianist Georgette Contoux Quante who had graduated with honors from the Conservatoire de Paris where she had studied under Alfred Cortot.
The couple moved to Guatemala in 1922 and two years later Castillo joined the faculty of the Conservatorio Nacional de Música in Guatemala City as a professor of harmony, music history, and composition; a position he maintained until his retirement in 1960.
[2] In 1948 Castillo submitted entries under pseudonyms in all three categories of the Science, Literature and Arts National Contest in Guatemala; and won all three prizes.
