Robert Balin created scores
of electronics-related quizzes for Popular Electronics magazine (see list at bottom of
page). Having appeared in the December 1965 issue, some of the subjects are a bit dated,
but hey, this is an electronics history quiz. I got 80% - yeah, sort of pathetic, but
I don't recall ever hearing of Heising and I couldn't figure out what item "A" was (hint:
it's a TV iconoscope, BTW). That left me with a guess between "A" and "G" for #9 and
#10, which of course I got wrong with a 50-50 chance.
Electronics History Quiz
By Robert P. Balin
Many present-day electronics devices have been
around for a long time, and some still bear the manes of their inventors. Try matching

9 Zworykin ___
10 Heising ___
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.

History Quiz Answers
1 - H - John A. Fleming applied for a patent for his diode vacuum tube in
1904. It utilized the Edison effect principle discovered 20 years earlier.
2 - B -
Ralph V. Hartley invented the oscillator circuit that bears his name. It uses a parallel-tuned
tank circuit with a tapped coil to provide the feedback voltage.
3 - C - Georges Leclanche invented the dry cell using a solid depolarizer
in 1868. To this day carbon-zinc dry cells are known as Leclanche cells.
4 - I -
Samuel F. Morse and his co-workers, Leonard Gale and Alfred Vail, demonstrated their
electromagnetic relay telegraph in 1838, using the original version of the dot-and-dash
code. The manual key, adopted later, was actually invented by Vail.
5 - D - Hans C. Øersted discovered, in 1819, that a magnetic field existed
around a current-carrying conductor.
6 - F - George W. Pierce was the first to apply a piezoelectric crystal to
a vacuum-tube oscillator circuit. This circuit, which now bears his name, is basically
a crystal-controlled version of the Colpitts oscillator.
7 - J -
Nicola Tesla invented the high-frequency oscillator transformer known as the Tesla
coil in 1891.
8 - E - Max
Wien developed the basic principles of a.c. bridges, and published a collection of
his bridge networks in 1891. The Wien bridge is used to make capacitance and frequency
measurements.
9 - A - Vladimir K. Zworykin invented the television iconoscope in 1923.
10 - G - Raymond A. Heising developed the constant-current form of plate modulation
that bears his name. This method of modulation is widely used in high-power broadcasting
stations.
