Mr Bradbury was a history teacher at Park Vale Comprehensive School. Sarah Jane Smith found him very boring. In 2008, he and Mrs Reiki took the class, which included Luke Smith, Maria Jackson and Clyde Langer, on an educational field trip to St Margaret's House Museum, after which they visited the Stone Whisperers. Mr Bradbury was locked out of the exhibit during Luke's mental battle with Ravage. (AUDIO: The Thirteenth Stone)
