Just 92 elements made up the world, but the belief that were only four - earth, fire, air and water - persisted until the 19th Century.

He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.
