Si Spencer is a British TV and comic writer from Sheffield.
Si was inspired to write by Viv Nicholls, his secondary school English teacher, finishing school in 1979. While already reading 2000AD, a housemate introduced him to Warrior and Yummy Fur, so that a conversation with Adrian Dungworth encouraged him to write comics.
Having worked on EastEnders, Si had talked socially to Vertigo editor Shelly Bond (an EastEnders fan). Si got a job writing the Books of Magic, as Neil Gaiman had wanted to explore the character Tim Hunter as a young man.
