Otto Beckmann (1908–1997) was an Austrian sculptor and computer artist.
There's also a lovely family, the Beckmann family. And Otto Beckmann was also using the computer in the early '60s. He and his son, Oskar, who's still alive, it's called the Beckmann Archive. And we have a lot of examples of his work on our site. His son built his computer.
