Radoslav Kvapil (born 15 March 1934 in Brno) is an internationally acclaimed Czech pianist and composer, considered by some to be the among the finest exponents of Czech piano music. However, at the end of the 20th century, he devoted his concert programmes to works by Frédéric Chopin, particularly in France, in the Chopin International Piano Festival in Nohant.

He has also recorded Studies by Chopin (coprod. Amat/Jean-Pierre Thiollet, 1999).

Jean-Martin Charcot (29 November 1825 – 16 August 1893; English pronunciation: /ʃɑrˈkoʊ/, US dict: shâr·kō′) was a French neurologist and professor of anatomical pathology. He is known as "the founder of modern neurology" and is "associated with at least 15 medical eponyms", including Charcot-Marie-Tooth disease and amyotrophic lateral sclerosis (motor neurone disease). Charcot has been referred to as "the father of French neurology and one of the world's pioneers of neurology".

His work greatly influenced the developing fields of neurology and psychology. He was the "foremost neurologist of late nineteenth-century France" and has been called "the Napoleon of the neuroses".

Born in Paris, France, Charcot worked and taught at the famous Salpêtrière Hospital for 33 years. His reputation as an instructor drew students from all over Europe. In 1882, he established a neurology clinic at Salpêtrière, which was the first of its kind in Europe. Charcot was a part of the French neurological tradition and studied under, and greatly revered, Duchenne de Boulogne.

Jean Martin (6 March 1922 – 2 February 2009) was a French actor of stage and screen. Martin served in the French Resistance during World War II and later fought with the French paratroopers in Indochina. Theatrically, he is perhaps best-known for originating two roles in Samuel Beckett's most famous plays: Lucky in Waiting for Godot, and Clov in Endgame. During the 1950s, he was a performer at the Théâtre National Populaire and also worked for radio plays.

Making over eighty film and television appearances, Martin is best remembered by international audiences for his role as the French paratroop commander Col. Mathieu in The Battle of Algiers (1965), as well as villainous roles in My Name is Nobody and The Day of the Jackal (both 1973). He was one of the protagonists in Les Compagnons de Baal (1968).

Most of his other screen work was in French or European cinema, and his stage performances have gained him much more recognition and acclaim than his film work. Martin was also an active political leftist, and was fired from the Théâtre National Populaire for signing the manifesto of the 121 against the Algerian War. He was also blacklisted from radio work and remained unemployed for a time as a result.
