As a naturalist, he made contributions in the fields of paleontology, geology, botany and zoology.
He was a member of the Société de géographie et d'archéologie d'Oran, serving as its president from 1912 to 1920, and then again from 1924 to 1928.
[1][2] Beginning in 1886, with zoologist Paul Maurice Pallary, he conducted paleontological explorations of several cave sites in the vicinity of Oran.
[3] In 1892 at the so-called "Abri Alain" (Kouchet El-Djir), the two men uncovered evidence of prehistoric human activity dating back many centuries.
Some of the archaeological pieces that were excavated later became part of the Ahmed Zabana National Museum in Oran.
