André Frédérique (27 February 1915, Nanterre - 17 May 1957) was a French poet.
 He was a son of a police officer.
 He became a member of the Parisienne bohème (befriending people like Jean Carmet).
 His works, often full of black humour (which did not save him from suicide caused by his feeling of a metaphysical hopelessness) are similar to Henri Michaux.
Henri Michaux (] ; 24 May 1899 – 19 October 1984) was a highly idiosyncratic Belgian-born poet, writer, and painter who wrote in French.
 He later took French citizenship.
 Michaux is best known for his esoteric books written in a highly accessible style.
 His body of work includes poetry, travelogues, and art criticism.
 Michaux travelled widely, tried his hand at several careers, and experimented with psychedelic drugs, especially LSD and mescaline, which resulted in two of his most intriguing works, "Miserable Miracle" and "The Major Ordeals of the Mind and the Countless Minor Ones".

 His entire catalogue is available on Columbia Records.
 His 1967 debut "Songs of Leonard Cohen" earned an RIAA gold record; he followed up with three more highly acclaimed albums: "Songs from a Room" (1969), "Songs of Love and Hate" (1971) and "New Skin for the Old Ceremony" (1974), before allowing Phil Spector to produce "Death of a Ladies' Man" for Warner Bros.

 Cohen returned to Columbia in 1979 for "Recent Songs", but the label declined to release his next album, "Various Positions" (1984) in the US, leaving it to American shops to import it from CBS Canada.
 In 1988, Columbia got behind Cohen again and gave full support to "I'm Your Man", which brought his career to new heights, and Cohen followed it with 1992's "The Future".
 Cohen then took a nine-year hiatus, and returned with "Ten New Songs" in 2001, which he made with Sharon Robinson, following this with "Dear Heather" (2004).
 In 2008 Cohen began touring for the first time in 15 years and, as well as the release of several live albums, he released "Old Ideas" (2012), which peaked at number three on the "Billboard" 200 albums chart.
 This was the highest ranking ever for a Leonard Cohen album, and it became his first to top the Canadian Albums Chart, a feat he repeated with his followup, "Popular Problems", released in 2014.
 His live albums included "Live Songs" (1973), "" (1994), "Live in London" (2009), "Songs from the Road" (2010), from his 2008–2009 world tour, and "Live at the Isle of Wight 1970" (2009).
