Barbara Wright (Jacqueline Hill) 1963-1965

School teacher Barbara is curious about one of her students – Susan Foreman. She persuades fellow teacher Ian to help her follow Susan home one day, and their lives are never the same again. Whisked off into space and time, historian Barbara encounters cavemen, Aztecs, ancient Romans and almost loses her head on the guillotine. She and Ian leave the Doctor using a Dalek time machine, and return to Earth – although two years after they had left!

After leaving the Doctor, she had an adventure with his eleventh incarnation, and at the end of that adventure, she married close friend and fellow companion Ian Chesterton.

As well as Ian, she traveled alongside Susan Foreman and Vicki Pallister and was acquainted with Steven Taylor.
