During the 20th century, the fund grew further with the legacies of and donations by artists and private collectors; the most important one was the 1960 donation from the collection of Vincenc Kramář, historian, art collector, and erstwhile Director of the Picture Gallery.
The subcollection of Czech sculptures numbers a sizeable convolution of works from the early 19th century by Václav Levý, Josef Malínský, Václav Prachner, through sets of works by František Bílek, Josef Mařatka, Ladislav Šaloun, Stanislav Sucharda, and Otto Gutfreund, to Zdeněk Pešánek’s kinetic sculptures, and the output of sculptors Mary Duras, Marta Jirásková, and Hana Wichterlová. Artistic legacies of Josef Václav Myslbek, Bohumil Kafka, and Jan Štursa constitute an important part of the collection.
The most significant component of the collection of international art is the collection of 19th and 20th century French art, containing paintings by Camille Corot, Gustave Courbet, Eugène Delacroix, Camille Pissarro, Auguste Renoir, Claude Monet, Alfred Sisley, Georges Seurat, Paul Gauguin, Vincent van Gogh, Henri de Toulouse-Lautrec, Paul Cézanne, Georges Braque, and Pablo Picasso, and sculptures by Jean Baptiste Carpeaux, Auguste Rodin, and Émile-Antoine Bourdelle. German and Austrian artists are amply represented too, with crucial works by Caspar David Friedrich, Ferdinand Georg Waldmüller, Max Liebermann, Lovis Corinth, Emil Orlik, Max Oppenheimer, Oskar Kokoschka, Egon Schiele, and Gustav Klimt. A less sizeable fund is made up of the works of Russian artists, such as Ilya Repin, Ivan Konstantinovich Aivazovsky, Aristarkh Vasilyevich Lentulov, and other European authors like Edvard Munch, Gino Severini, and Constantin Meunier.
The Collection of 19th Century Art and Classical Modernism therefore administers the most comprehensive set of Czech paintings and sculptures from the 19th and the first half of the 20th century, as well as the most important convolution of 19th and 20th century foreign authors working in the Czech lands. The Collection was created in 2018 by merging the original Collection of 19th Century Art with a part of the Collection of Modern and Contemporary Art dedicated to artists born at the turn of the 19th and 20th centuries whose works – most of them, at least – were made before 1945: for example, Emil Filla, František Kupka, Josef Šíma, Toyen, and Georges Braque, Oskar Kokoschka, and Pablo Picasso among the foreign authors.
