Another engaging read for my seven-year-old who loves inventing and engineering. We get a good sense of young Thomas' world and interests, without getting too bogged down in facts or extensive detail, and Guthridge makes a good effort at trying to include details about Edison, such as his small stature (as a boy) or his little quirk of pulling at his eyebrow when he was getting an idea. (At least, I hope that is historically accurate. One big knock against this series is that the books do not include Bibliographies. I think most of them pull from one advanced biography on the subject and I realize many of these CoFA books were written forty or fifty years ago but I do think reprinted editions should include more back matter for students today.) Unlike some of the other CoFA books we've read, this one really does focus almost exclusively on Tom's boyhood, from about age six to about age fifteen. Much of the focus, then, is on his interest in chemistry and Morse code and the newspaper that he started. There's only one chapter that involves his later life and inventions. Really appreciate the focus on how Tom was largely self-taught as a boy, and kudos to his mother for her stellar job of homeschooling as well as allowing her son to follow his passion from a young age. I appreciate, also, that we see some of the failures, such as when he thought he could make his friend fly if the friend drank a mix of chemicals that would gas up and "inflate" his stomach. Oh my gosh! (Thank goodness the friend was only mildly sick!) Young Tom almost lost his laboratory over that, but he promised his mother he would never give his concoctions to anyone again and she knew he was learning so much in his self-made laboratory that she relented, so long as it was kept locked and Father had the key! Tom kept his word and the rest, as they say, is history ;-)
