Nicholas Skinner
From Tardis Wiki, the free Doctor Who reference
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)
