He was a pupil of Alkan, Ignaz Moscheles and Adolf von Henselt. He made successful tours of England, Germany and Russia, and travelled with Henri Vieuxtemps and Henryk Wieniawski. During the Franco-Prussian War of 1870, he escaped from France to London with his 121 parrots and cockatoos. He also shared his rooms with two apes, one of which he named Isadora, in honour of Isidor Philipp. In 1873 he was appointed professor at the Paris Conservatoire, where his pupils included Olga Samaroff (one-time wife of Leopold Stokowski) and Marie Poitevin, the first performer of César Franck’s Prelude, Chorale and Fugue in 1885. Other pupils were Carrier-Belleuse, Loire, Lefour, Haincelain and Aline van Barentzen.

Delaborde was a fencer, a passionate athlete, a bon vivant and a ladies’ man. He also painted under the pseudonym “Miriam”, and was a close friend of Édouard Manet. Camille Saint-Saëns’ Piano Concerto No. 3 was dedicated to Delaborde. He was in the circle of Pauline Viardot, Ivan Turgenev and Ernest Guiraud, and became a close friend of Georges Bizet. Delaborde may have been indirectly responsible for Bizet’s death, which followed a swimming competition between the two, as a result of which Bizet caught a chill. After Bizet’s death, Delaborde formed an alliance with his widow Geneviève, and they were even engaged to be married, but the engagement was broken off. In 1901 he became engaged to a much younger pupil, but it also failed to result in marriage.

Delaborde died on 9 December 1913, aged 74, and was buried at Père Lachaise Cemetery on 11 December.

Delaborde’s output is significant, but minimal attention has been given to his works. The first acoustic recording in history of one of Delaborde’s compositions was Étude d’après une petite Valse de V. Dolmetsch, recorded by Vincenzo Maltempo in 2014, as a part of the Rarities of Piano Music at the “Schloss vor Husum” Festival.
