Biography
A renowned scientist, Rubeish was near-blind and had to wear powerful spectacles. In his time at UNIT, Rubeish became acquainted with the Third Doctor. He welcomed Sarah Jane Smith, believing her masquerade as her aunt the virologist Lavinia Smith.

Rubeish was transported to the Middle Ages and almost hypnotised by Linx, the Sontaran who kidnapped him. He was saved by his low vision. He found a microscope lens and heated it so he could see more clearly.

He snapped the other scientists out of hypnosis and teleported them back to the 20th century. He was the last man to return to the 20th century. (TV: The Time Warrior)
