Ernest Benjamin Esclangon ( March 17, 1876January 28, 1954) was a French astronomer and mathematician.

Born in Misson (near Sisteron ), France, in 1895 he started to study mathematics at the École Normale Supérieure, graduating in 1898. Looking for some means of financial support while he completed his doctorate on quasi-periodic function s, he took a post at the Bordeaux Observatory , teaching some mathematics at the university .

During World War I, he worked on ballistics and developed a novel method for precisely locating enemy artillery. When a gun is fired, it initiates a spherical shock wave but the projectile also generates a conical wave. By using the sound of distant guns to compare the two waves, Escaglon was able to make accurate predictions of gun locations.

After the armistice, Escaglon became director of the Strasbourg Observatory and professor of astronomy at the universityJohann Wolfgang Goethe The University of Strasbourg in Strasbourg, Alsace, France, is divided into three separate institutions.
