Tommy Watkins
From Tardis Wiki, the free Doctor Who reference
Tommy Watkins was a soldier who fought the Battle of Spion Kop in the Second Boer War in 1900. He was killed in action and his coat made its way to an antique shop in the 1970s where it was bought by Jo Grant's friend Roddy Fletcher. Roddy was possessed by it soon afterwards.
The First Doctor, Dodo Chaplet and Steven Taylor met him during the war, where he was inhabited by an alien being, Kali Carash. (AUDIO: Tales from the Vault)
