Jacques Curie (29 October 1855 – 19 February 1941) was a Frenchphysicist and professor ofmineralogy at theUniversity of Montpellier.^[1] Along with his younger brother,Pierre Curie, he studiedpyroelectricity in the 1880s, leading to their discovery of some of the mechanisms behindpiezoelectricity.^[2]

He is buried in the Saint-Lazare cemetery inMontpellier.

In 1883, Jacques Curie was appointed professor ofmineralogy at theUniversity of Montpellier. This appointment marked the end of his collaboration with his brotherPierre. He remained inMontpellier until his death in 1941 with the exception of the years 1887–1889, which he spent inAlgeria, teaching at the School of Science of Algiers and conducting his research.^[3] It was not until 1903 that he was appointed to the chair of physics, a position he retained until his retirement in 1925. His sonMaurice Curie was a physicist.

The major legacy of Jacques Curie is the discovery of thepiezoelectric effect with his brotherPierre in 1880. The two brothers were then laboratory assistants at the Faculty of Sciences of Paris, under the direction ofCharles Friedel. The accounts of their discovery generally give Jacques Curie only a minor role in favor of his brother Pierre. Doubtless the comparison between the latter's brilliant career and the more quiet one of Jacques gives some reason for this, however there is no evidence that Jacques was limited to a minor role:^[4] In particular he had more experience than his brother in the study ofpyroelectricity. In fact it is almost impossible to clearly separate the contributions of the two brothers as they constantly shared their ideas. According to Shaul Katzir,^[4] one must consider the discovery as a joint contribution.

TheCurie–von Schweidler law refers to the response ofdielectric material to the step input of a direct current (DC) voltage first observed by Jacques Curie^[5] and Egon Ritter von Schweidler.^[6]
