Nicholas Skinner

Professor Nicholas Skinner was an astronomer at the Tycho Radio Telescope in the rural English village of Goblin's Copse. He had a daughter, Lucy, whom he hoped would follow him into astronomy instead of chemistry, like her mum.

Professor Skinner was captured by Commander Kaagh, a [{Sontaran]] determined to avenge his people's defeat (in DW:The Sontaran Stratagem / The Poison Sky), and forced to do Kaagh's bidding. He was freed by the actions of Sarah Jane Smith and her friends. (SJA:The Last Sontaran)
