The First Doctor travelled with his Granddaughter, Susan Foreman. They lived in the TARDIS, which was parked inside a Scrap Merchant (I.M. Foreman - Scrap Merchant on Earth. Susan attended a school, which she loved, although she couldn't help herself correcting her teachers when they got History wrong. Her teacher, Barabra Wright and head teacher, Ian Chesterton followed her back to her house as she was acting very mysteriously and they wanted to speak to her grandfather. The Doctor whisked them away [see: Companions < Susan Foreman and school teachers] and that was the start of the 1st Doctors travels.
