Herbert W. Franke (14 May 1927 – 16 July 2022) was an Austrian scientist and writer. Die Zeit calls him "the most prominent German writing Science Fiction author". He is also one of the important early computer artists (and collectors), creating computer graphics and early digital art since the late 1950s. Franke was also active in the fields of future research as well as speleology. He used his pen name Sergius Both as this Avatar name in Active Worlds and Opensimulator grids. The Sergius Both Award is given for creative scripting in Immersionskunst by Stiftung Kunstinformatik, first time issued at Amerika Art 2022.
