The two Maxim brothers were prolific later nineteenth century inventors who revolutionised modern warfare. Hiram's invention of the eponymous Maxim gun changed the face of warfare, expressed most horribly in the slaughter in the First World War, but his work covered far wider fields, taking in gas and electric lighting, some of the most significant early experiments in heavier-than-air flight, and even the construction of fairground rides ; Hudson came to be one of the United States' leading explosives experts. This is a compelling story of human ambition, sibling rivalry and fearsome invention.
