One of the first battery operated quiz games, the Knapp Electric Questioner (circa 1928-
1930) had various sets of quiz cards ranging from flags to animals to trivia. Inventor
David Knapp marketed this game at a time when there was an interest in the concepts of
electricity and communications. Upon completing the circuit by touching the two probes
to the correct question and answer a buzzer would sound powered by a battery inserted
on the board that included Morse and conventional telegraph codes.
