Rene Just Hauy

Born in 1743 in France, René Just Haüy was ordained as a Roman Catholic Priest at the College of Lemoine, and later became a teacher there. Haüy was first fascinated with botany, but that interest gave way to mineralogy when he accidently smashed a specimen of calcite and found himself captivated by the fragments. Subsequent experiments with the fragments led him to define a geometrical law of crystallization.

He is now recognized as a pioneer in crystallography, the study of the arrangement of atoms in solids. His name is one of the 72 etched into the Eiffel Tower.
