Croatian sculptor, painter, graphic artist and designer Aleksandar Srnec studied at the Academy of Fine Arts in Zagreb from 1943 to 1949. He is one of the founders of the group "EXAT 51" and a signatory of the 1951 and 1953 manifestos.

He realized his artistic expression in radicalized geometric abstraction. In the early 1950s, he constructed the first freely composed mobile kinetic objects, then around 1956 he began experiments with moving sculptures and reliefs. From 1962 he devoted himself to lumino-kinetic research, from 1968 to the problem of complete ambience and the creation of kinetic sculptures in highly polished metals, and he also experimented with pure light. For a short time he was involved in cartoons (1959–60). He received the "Vladimir Nazor" Award for Lifetime Achievement (1999). Aleksander Srnec's geometric abstraction is a radicalized form of post-war abstraction in modern Croatian art.
