At Wired, they have a great little slide show covering the history of the space suit. I especially like the anecdote form Yuri Gagarin:
After reentry, Gagarin had to eject from his spacecraft and parachute down to the ground. He landed in a field, where a farmer and her daughter spotted the strange sight of a man clad in a bright orange suit with a large white helmet. Gagarin later recalled, “When they saw me in my space suit and the parachute dragging alongside as I walked, they started to back away in fear. I told them, don’t be afraid, I am a Soviet like you, who has descended from space and I must find a telephone to call Moscow!”
You better believe that’s going in the book.
