Ernesto de Quesada López Chaves (1 November 1886 — 1972) was the Cuban-born impresario who founded Conciertos Daniel, the classical music management agency now known as Hispania Clásica.
After he completed high school and college, he devoted himself for a time to teaching guajiros how to read, riding his horse or walking long distances to reach them.
There he studied English for some months in Boston, Massachusetts, attending church on Sundays to listen to the services and accustom his ears to the new language.
As he was only 22 years old and the agency's sole proprietor, he invented an imaginary senior business partner, "Herr Heinrich Daniel," who was said to be out of town whenever anyone asked to speak to him.
"[21] With fellow impresario Sol Hurok and others, de Quesada was present when Daniel Barenboim (then age 13) and Arthur Rubinstein met for the first time, in Paris in 1955.
