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 a day or two), but a couple just might stump you. This Electronics Inventors Quiz appeared in a 1963
edition of Popular Electronics, 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
[Table of Contents]People old and young enjoy waxing
nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October
1954 through April 1985. As time permits, I will be glad to scan articles for you. All copyrights (if any) are hereby
