I looked this up the other day just for the fun of it … and because I had never paused to think why PIs used to be called gumshoes. But according to etymology.com:

“plainclothes detective,” 1906, from the rubber-soled shoes they wore (which were so called from 1863); from gum (n.1) + shoe (n.).

Obvious, yes. But still fun. =) And a nice start to the week I plan on preparing my “History of Spies in Early America” home school group class. 😉 Got the Creative Writing one mostly done yesterday. Yay!

Hope everyone has a great week!
