Alfred Denis Cortot (Nyon, Switzerland September 26, 1877 -- Lausanne June 15, 1962) was a Franco-Swiss pianist and conductor. He is one of the most popular 20th century musicians, especially renowned for his poetic insight in Romantic period piano works, particularly those of Chopin and Schumann. From 1907 to 1923 Cortot taught at the Paris Conservatoire, where his pupils included Clara Haskil, Dinu Lipatti, Vlado Perlemuter, and even Marguerite Monnot, French composer of most of the best songs of Edith Piaf and of the 1956 stage musical Irma la Douce. In 1919 he founded the École Normale de Musique de Paris. His courses in musical interpretation were legendary. Extremely widely traveled as a pianist, he also appeared as guest conductor of many orchestras. Cortot also wrote a good deal of didactic prose, including a piano primer: Rational Principles of Pianoforte Technique. This book contains many finger exercises to aid in the development of various aspects of piano playing technique. It was originally written in French but has long since been translated into other languages.
