Christopher Lloyd (born 1 April 1968) is a historian, educationalist and author, best known for his sweeping narratives on big history (the history of the world). He is the author of the best selling book What on Earth Happened: The Complete Story of the Planet (Bloomsbury, 2008)[1], which has sold 500,000 copies. Lloyd is a keen advocate of connected learning. In collaboration with Beckenham-based illustrator Andy Forshaw, Lloyd has established a format for telling giant narratives to young people by using illustrative timelines called Wallbooks,[2] which present a broader view of world history and visualise connections between the past and the present day.

A worldwide cultural phenomenon and the highest-grossing film of 1985, Back to the Future launched one of the most successful franchises in Universal's history, including two theatrical sequels, an animated television series, a theme park ride, toys, comic books, video games and apparel.
