Electronics Inventors Quiz
November 1963 Popular Electronics

November 1963 Popular Electronics

November 1963 Popular Electronics Cover - RF CafeTable of Contents

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Most of these matches of the devices and its inventor are pretty easy for people who have been around electronics for any length of time (well, not if the length of time is only a day or two), but there are a couple that just might stump you. This "Electronics Inventors Quiz" appeared in the November 1963 issue of Popular Electronics magazine, so you won't be challenged with knowing the inventors of the LCD or MEMS devices, but neither will you have to know who came up with the abacus or the Archimedes screw :-). I managed to score 100%, but that was admittedly partly luck in deciding between two men for items "B" and "C." The other eight should be a piece of cake for most RF Cafe visitors.
