Dedicated to Leonardo da Vinci, this latest wonderful offering from Marcia Williams is full of her characteristic humour. Packed with cartoon-strip illustrations and short biographies, it looks at the discoveries of many famous - and not so famous - inventors from around the world, including Leonardo da Vinci, Antonio Meucci, Alexander Graham Bell, John Logie Baird, Thomas Edison, James Watt and many of their predecessors. Three cheers for inventors!
