I just read this this morning. It's a light read with just enough technical information to make it interesting. The engineer's name was Frank Walker and he helped to pioneer water injection. From what I gleaned from the profile, he was also instrumental in discovering how to use super lean efficiency ratios (LOP). Sorry for the crude link; I can't embed links with an iPad.
