Eddie Smith

Eddie Smith was the brother of Lavinia Smith, the husband of Barbara Smith, the father of Sarah Jane Smith and the adoptive grandfather of Luke Smith and Sky Smith.

Timeline 1
Eddie and his wife died on 18 August 1951, the day of the Foxgrove village fete. They drove off in their car, leaving their three-month-old baby behind in the pram. Sarah Jane Smith was subsequently brought up by Lavinia.

Timeline 2
Sarah Jane and her son Luke travelled from 2009 to meet Eddie and Barbara, and Sarah Jane decided to save them by deactivating their car so they would not be able to escape. However, while this change in and of itself had no major effect on the timeline, meddling with history near an unstable rift in time caused the rift to open, allowing the Trickster to fully materialise on Earth and conquer the world.

Timeline 3
After Sarah Jane returned to 1951 Foxgrove from the alternate timeline her parents' survival had created, Eddie and Barbara quickly worked out who Sarah Jane was and what they had to do. They decided to sacrifice themselves to save her world. (TV: The Temptation of Sarah Jane Smith)
