Bogoslav Kalaš is a Slovenian artist who, since 1982, has worked as a professor at the Academy of Fine Arts in Ljubljana, where he served as dean from 1998 to 2005. An important note to Kalaš’s biography is the fact that he developed and invented his own painting technique, which he calls aerography. He has been continuously developing it since 1971. The technique is based on the principle of transferring a motif onto canvas or paper with a mechanical painting machine. Kalaš’s work has been presented in various exhibitions at home and abroad, including the Museum of Modern Art, Ljubljana; Galerija Gregor Podnar, Berlin; City Art Museum, Ljubljana; steirischer herbst, Graz; Centre of Graphic Arts - MGLC, Ljubljana; Latvian Centre for Contemporary Art, Riga, and many others. For his oeuvre, in 2006, he received the most prominent and prestigious Slovenian award for visual arts, the Rihard Jakopič Award.

Kalaš’s art practice stretches back to the late 1960’s and has focused on classic subjects, which art history traditionally categorises by genre: the still life, the landscape, and the nude or, more generally, the portrait. His works are notable for the remarkable way in which they continue and expand on the tradition of figurative painting within the field of graphic art. In this context, it is important to relate the work of Bogoslav Kalaš to the work of Gerhard Richter, with whom Kalaš dialogues about causes, methods, and timings While Richter’s offset lithographs were created on the basis of  photographs from the 1980’s, Kalaš had already started to produce his “aerographies,” made by a prototype painting machine, in the early 1970’s. This makes him a pioneering figure in the development of painting in the second half of the twentieth century.
