Discovery of the piezoelectric phenomena

Piezoelectric phenomena were discovered by the Curie brothers (Pierre and Jacque Curie) in 1880 while conducting an experiment on pyroelectricity (10).

This does not mean no one had paid attention to this phenomenon before the discovery. A paper authored by Cady says that Hauy and Becquerel conducted an experiment and found that some crystals generate electricity when pressure is applied to them as predicted by Coulomb (11). Becquerel actually published a paper on piezoelectricity in 1823 (12).

[Please note]
There is sparse information about research history of the pyroelectricity/piezoelectricity effects caused by tourmaline. We refer to and quote from this literature as the events are presented in chronological order.
