Hauy
René Just Haüy was a French mineralogist and crystallographer born on April 28, 1743, in Saint-Julien, France. He is widely regarded as the founder of modern crystallography, a branch of science that studies the geometric properties of crystals. Haüy’s work laid the groundwork for understanding the internal structure of minerals and their symmetrical forms.
Haüy initially trained as a priest but later shifted his focus to science after observing the way
Haüy’s most influential work, *Traité de Minéralogie* (1793–1801), systematically classified minerals based on their crystalline forms
Beyond mineralogy, Haüy contributed to education, serving as a professor at the École Polytechnique in Paris.
His work remains foundational in understanding the atomic and molecular arrangements in crystalline solids, bridging early
