Telling Tommy (and how!)

Some years ago, a jolly old neighbor of my grandmother's passed away. One of his possessions which came into my hands was a series of childrens books entitled Telling Tommy, by Paul Pim and (c)1942 Cupples and Leon. An educational series if you must, these books introduced children to facts and ideas in the form of an illustrated father smoking a pipe (or in this case, "Uncle Jack") and chatting with his son.
The post below jogged my memory a bit...and you'd never guess what I found in TELLING TOMMY about Famous Inventors.
