The family was forced to flee to Austria in 1922 where Otto Beckmann graduated from the HTL (Federal Secondary College of Engineering) in Moedling near Vienna and the Academy of Fine Arts in Vienna. In 1941, he became professor at the Institute for Arts and Crafts in Kraków.
Since 1945, he lived as an independent artist in Vienna and was a member of the Austrian Professional Association of Fine Arts. In 1951, he became a member of the Vienna Secession. In 1958, he was bestowed the professor title by the Austrian Federal Chancellor.
In 1966, he founded ars intermedia in cooperation with scientists of the Technical University Vienna. He participated in the international symposium on computer art in Zagreb and is regarded as “one of the pioneers of media and computer art” (Peter Weibel)
Otto Beckmann had 25 personal exhibitions and participated in more than 75 exhibitions in Austria and abroad.
The comprehensive and manifold art work by Otto Beckmann took place in the broad field between mystics and algorithms. It comprises paintings and sculptures as well as new forms of expression like abstract films and imaginary architecture (1966).
His works are in the Albertina, Vienna; the Austrian Federal Ministry of Education; the State Museum of Lower Austria, MUSA Vienna; Neue Gallerie Graz; Kunsthalle Bremen, Germany, ZKM Karlsruhe, Germany; as well as numerous private collections. Beckmann created a great number of mosaics on Vienna residential buildings as well as windows and doors in sacred buildings by Robert Kramreiter.
In 2005 the Archiv Otto Beckmann was founded by his son Richard.
