NOTES: Bob was born, raised, and began his preliminary education in New York. Later, when his career decision became definite, he moved to London for the best training possible. That decision was to learn the science of psychiatry. So while Helena Russell looks after the physical well-being of Alpha residents, Mathias looks after the mental and emotional aspects. He leaves the surgery to Helena and she leaves the soul-searching to him. Another of Bob's talents that comes in handy during the long Alphan nights is his expertise at chess. An avid player, he holds seemingly endless bouts with Moonbase's other resident expert, David Kano. Although he was well liked in his medical position, Bob thought it best to transfer to the Data Section so he could better study man's stress factors in deep space. He was replaced in the Medical Center by Dr. Ben Vincent.
