Krzysztof Michał Bednarski (KMB) (25 July 1953 in Kraków) is a contemporary Polish-Italian sculptor.
He was one of three sons of Irena and Jerzy Bednarski. Before the war, his parents lived in Lwów on Kulparkowska Street. Bednarski completed the XIV High School of General Gottwald in Warsaw. Later he graduated from the Academy of Fine Arts in Warsaw (1973-1978) in the sculpture department in the studios of Jerzy Jarnuszkiewicz and Oskar Nikolai Hansen. His diploma was entitled Portret Totalny Karola Marksa (Karol Marx’s Total Portrait) and was defended on July 5, 1978. He was later associated with the theater of Jerzy Grotowski, for which, during the period from 1976-1981, he designed posters. At that time, his first son was born and he worked at the quarry in Borów. Since 1986, he has been living in Rome, Italy. In the academic year 1996/97 and 2014-2017 he was a guest lecturer at the Academy of Fine Arts in Warsaw. In 2014, he defended his doctorate at the Academy of Fine Arts in Warsaw for his work W stronę rzeźby, czyli historia jednego dzieła bez końca (In the direction of sculpture, the story of endless work on one subject). In his early work, he criticized the communist propaganda in Portret totalny Karola Marksa (1978) (Total Portrait of Karl Marx) which is currently in the collection of the Museum of Independence in Warsaw or in Portret zbiorowy (1980) (Collective Portrait) which is currently part of the collection of the National Museum in Warsaw. He alluded to the political situation in Poland under the martial law in work such as Victoria-Victoria (1983) which is now part of the collection of the National Museum in Kraków. One of the recurring motifs in his oeuvre is Moby-Dick; its 1987 installation is currently in the ms2 collection of the Art Museum in Łódź. Bednarski acted in several movies such as Noc poślubna w biały dzień (1982) (The Wedding Night During the Daylight), Schodami w górę, schodami w dół (1988) (Walking the Steps Up and Steps Down) and he played himself in My Italy (2017).
