A friend of Francis Bacon and Lucian Freud, he published a memoir in 1977 entitled High Diver (in French Le Saut de l'ange), which caused a scandal with its description of his bohemian lifestyle.
His godmother was the collector Peggy Guggenheim, and his half-sister Yasmin was the daughter of Laurie Lee.
It was given a glowing review by David Sylvester who had hung the exhibition for him, so much so that Wishart stated that he had been overawed by the reaction, giving him doubts as to whether he would be able to live up to it.
"[2] He married on June 12, 1950, the artist Anne Dunn, with whom he had a son in 1953, Francis.
[3] Wishart wrote a second volume of memoirs, entitled Injury Time, which is yet to be published.
