Jean Jallabert investigating the effects of points and knobs on electrical discharges
3614200 Jean Jallabert investigating the effects of points and knobs on electrical discharges, from Les Merveilles de la Science, pub.1870 by French School, (19th century); (add.info.: Jean Jallabert, 1712-1768, investigating the effects of points and knobs on electrical discharges whilst standing on a wax insulating platform, one hand touching an electrostatic generator and the other holding a pointed piece of wood. When its point neared one end of a conducting rod mounted on a pivot, the deflection of the rod caused by the discharge showed whether there was a positive or negative charge.

EDITORS COMMENTS
This print captures the brilliant mind of Jean Jallabert, a renowned 18th-century scientist, as he delves into the fascinating world of electrical discharges. Standing on a wax insulating platform, Jallabert fearlessly explores the effects of points and knobs on these mesmerizing phenomena. In this historical moment frozen in time, we witness Jallabert's dedication to scientific research. With one hand touching an electrostatic generator and the other firmly holding a pointed piece of wood, he meticulously observes the behavior of electrical charges. A conducting rod mounted on a pivot becomes his indicator - its deflection revealing whether there is a positive or negative charge present. The image showcases not only Jallabert's expertise but also his innovative approach to understanding electricity. His experiments paved the way for groundbreaking discoveries in physics and mathematics. Published in Les Merveilles de la Science in 1870, this illustration transports us back to an era where scientific exploration was at its peak. It serves as a testament to human curiosity and our relentless pursuit of knowledge. Through this remarkable photograph by Ken Welsh from Fine Art Finder, we are reminded of the immense impact that individuals like Jean Jallabert have had on shaping our understanding of electricity and their invaluable contributions to scientific history.
