Samuel Morton Peto

Samuel Morton Peto was, as the Fifth Doctor put it, a legendary construction genius. He worked with his cousin Thomas Grissell, on the construction of Nelson's Column.

On the 23rd October 1843, both Peto and Grissell were possessed by Sevakrill who killed and ate twelve humans who were due to dine with them atop the column. The Fifth Doctor confronted them and managed to appeal to the both to build a mental barrier between themselves and the host. They managed to do so and both were freed. It took them some time to recover and the forgot all about the incident. The Doctor decided not to tell them that the stomach pain they had was a result of digesting human meat.
