John Robson was the head of a Euro Sea Gas refinery.
Robson refused to believe the base was under attack by the weed creature, stubbornly insisting that the problems the refinery was experiencing were due to a mechanical fault. He believed the Second Doctor was a saboteur, and wouldn't listen to Frank Harris and Van Lutyens's advice to shut off the gas supply. He fell under the Weed Creature's mental control, but was eventually freed thanks to the Doctor. (TV: Fury from the Deep)
