As a boy, observing a robin catch a worm and then take flight, he fed a playmate a mixture of worms and water to see if she could fly! Here’s an accessible, appealing biography with 100 black-and-white illustrations.

IT TOOK THREE HUNDRED MEN TWO YEARS TO BUILD IT. IT IS MADE OF FIFTEEN THOUSAND PIECES OF IRON HELD TOGETHER BY 2.5 MILLION RIVETS. IT CAN SWAY ALMOST FIVE INCHES IN STRONG WINDS.
