July 1967 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.

Test your knowledge of the country of origin of the inventors responsible for these ten inventions by taking this "International Electronics Quiz." It appeared in the July 1967 issue of Popular Electronics magazine. In some cases the inventor was born in another country but then emigrated to the U.S. or another country before his/her invention or discovery. This is a pretty tough quiz even for someone who has done a lot of reading on the history of technology. Guessing the country of origin for the inventor of the voltaic pile might be easier if you recall the guy's name (hint: his name is in the caption), and for the TV antenna take note of the configuration of the elements (hint: there was nobody named Log Periodic). I'm too embarrassed to divulge my score, but if you do better 50% or better, you've beaten me.

International Electronics Quiz

International Electronics Quiz, July 1967 Popular Electronics - RF Cafe

By Robert P. Balin

Recent technological advances in the field of electronics tend to overshadow contributions by earlier scientists from many parts of the world. For example, few students remember that the first known magnetic device - the compass - is a contribution from China, or that the theoretical groundwork in the field of atomic physics which eventually led to the splitting of the atom by the United States, was actually laid by Albert Einstein, the German-born physicist, while doing research work in Switzerland. To test your biographical knowledge of some earlier scientists and their inventions, see how many of the common electrical devices (A-J) illustrated below you can associate with the country of origin (1-10) of their inventors.

1   Belgium ___

2   Denmark ___

3   England ___

4   France ___

5   Germany ___

6   Holland ___

7   Italy ___

8   Japan ___

9   Russia ___

10 U.S.A. ___

 

 

See answers below.

Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, and Radio News were published over the years - some really simple and others not so simple. Robert P. Balin created most of the quizzes for Popular Electronics. This is a listing of all I have posted thus far.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
