Barthold "Bart" Fles (February 7, 1902 – December 19, 1989) was a Dutch-American literary agent, author, translator, editor and publisher.
[1][2] Among his many clients were Elias Canetti, Raymond Loewy, Heinrich Mann, Joseph Roth, Felix Salten, Ignazio Silone, Bruno Walter and Arnold Zweig.
[2] In New York Fles found temporary employment as a violinist, painting apartments, selling vacuum cleaners and working for publishers.
This book was clearly outside his (music and literature) expertise and sealed his writing for publication, set aside an intro to More by Dell Shannon (1982), by his prolific client Elizabeth Linington.
Subsequently, he returned to his native Netherlands,[18] where he spent his last three years in Laren's Rosa Spier home for retired artists.
[4][19] At Rosa Spier he was approached by Madeleine Rietra, a Dutch expert on German literature, who posthumously published his letter exchange with clients Joseph Roth (bookchapter in 1991)[4] and Heinrich Mann (book in 1993),[20] along with commentaries and biographical notes.
