Dr Samantha Madigan worked in the anthropology department at the Museum of Culture in Ealing in 2011. She was an expert on Native American culture.

Samantha knew of Hetocumtek's legendary powers. She explained the story of Hetocumtek to Sarah Jane Smith, Rani Chandra, Clyde Langer and Sky Smith. After Clyde had been cursed by the totem pole, she accidentally said his name, and threw him out of the museum. After lightning struck out of the totem pole, she called in Sarah Jane, who urged her to close the museum until further notice. (TV: The Curse of Clyde Langer)
