(Born: Tritt Saint Léger, France, 25 July 1858; Died: Paris, France, 11 July 1936) French mineralogist & crystallographer.

Educated at the Lycée of Marseille and the École Normale Supérieure in Paris, Wallerant was appointed professor of mineralogy at the University of Paris, where he remained from 1903 to 1933. Wallerant authored many papers on mineralogy and crystallography. He was elected to the Paris Academy of Science in 1907 and he was president of the French Mineralogical Society in 1905 and 1916.

Scarce. A mineralogy textbook which contains many original observations in its treatment of physical and chemical characters and descriptive mineralogy. Based on Lapparent's Cours de Minéralogie (1st ed., Paris, 1884) and Mallard's Traité de Cristallographie (Paris, 1879-84), this book is clearly a more advanced text then is normally encountered, with the subject being explained from the standpoint that the reader is already knowledgeable in mineralogy. Treatment is given to both crystallography and mineralogy. It is well illustrated with renderings of crystal drawings, as well as mineral specimens.

Sections: Livre Premier-Cristallographie. Introduction (pp. 1-2). I. Etude générale des formes cristallines (pp. 3-60) II. Etude des systèmes cristallins (pp. 61-139). Livre II-Minéralogie Physique.

Scarce. Crystallography textbook which contains many original observations and research by the author. It is throughly scientific and treats especially twinning, polymorphism, isomorphism and epitaxy, regular groupings of crystals, and optical anomalies. It was written as a completion of E. Mallard's Traité de Cristallographie (Paris, 1879-84), for which a third volume was never published.

Very scarce. This is Wallerant's detailed investigation of crystallographic twins. It contains a very useful historical survey of the literature of the subject.
