Eric Stahlmann

Director Stahlmann was a version of Professor Eric Stahlman from a parallel universe visited by the Third Doctor. Unlike his bearded counterpart in the primary universe, Stahlmann was clean-shaven and wore dark-tinted spectacles.

Stahlmann headed the Inferno Project, aided by the Republican Security Forces. He refused to accept the project was failing. He became infected by Stahlman's ooze and mutated into a Primord. He was killed by Greg Sutton with a fire extinguisher. (TV: Inferno)
