Eustacius Jericho

 was a professor who lived in Medderton.

He had fought in World War II and was one of the first British soldiers to enter Belsen at the end of the war. By 1967, he had neither a partner, nor any children. A Weeping Angel called his life a "life of failure".

On 21 November 1967, he was conducting a lie detector test on Claire Brown when he encountered the Thirteenth Doctor and the Weeping Angels. He managed to stall the Angels until he blinked and was sent back to 1901 where he met Yasmin Khan and Dan Lewis. (TV: Village of the Angels)
