an Austrian computer scientist, in the late 70s and 80s affiliated with the [[Vienna University of Technology]]. Along with [[Hermann Kaindl]], [[Helmut Horacek]] and [[Roland Schreier]], Marcus Wagner was co-author of the chess program [[Merlin]], competing at various [[ACM North American Computer Chess Championship|ACM North American Computer Chess Championships]] and two [[World Computer Chess Championship|World Computer Chess Championships]] in the 80s <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=353 Merlin's ICGA Tournaments]</ref>.

DePauli-Schimanovich further mentions the problems Wagner had in maintaining and testing Merlin at the university [https://en.wikipedia.org/wiki/Data_center data center]. Merlin often crashed the standard editor and operating system of the [[CDC Cyber|CDC Cyber 73]], and Wagner got the hell from the head of interdisciplinary practical, [http://de.wikipedia.org/wiki/G%C3%BCnther_Vinek Günther Vinek], who obviously was not a computer chess supporter ...

... opposed to Schimanovich, or Kaindl's advisor [[Wilhelm Barth]], a computer chess programmer himself. According to DePauli-Schimanovich, Vinek's attitude was not conducive to Wagner's further studying at the TU.
