He starts by paying homage to the great boiler men of the past: Evans, Stephenson and Robert Fulton. Stephenson is especially interesting because he was illiterate til he was 18 and some of his inventions were presumed to be stolen because he had such a gruff exterior.
Hawkins begins his book by explaining what goes through his mind when he arrives at the shop, smells the air, and looks around:
That's beautiful, isn' it? Few things are more interesting in print than a man explaining his passion for his work. Imagine what Shakespeare or Eugene O'Neil could have done with raw material like this!
I guess I don't have room to discuss another unusual book I've come across: Wernher Von Braun's "Mars Project." The book was published in 1948 and outlines Von Braun's dream of going to Mars and back with 4 - 6 V2 type rockets lashed together. The trip would take 9 months each way with only a small time spent on the planet's surface.
If you've never heard of this it may be because Von Braun believed an Earth-orbiting space station had to be built first, and he was talked out of that by a young American engineer from the Grumman company.
