It seems likely that one of the first references to brain herniation were by Collier1 and Alquier,2 who described cerebellar tonsillar herniation. In 1904, Collier reported:

A year later, Alquier described 2 cases that he designated “hetrotope du cervelet dans le canal la rachidien,”2(p1117) which translates to heterotopies of the cerebellum in the spine (rachidian canal). In this article, he wrote about 2 cases with brain tumors and commented that the autopsy showed tissue displacement “forced to migrate due to the pressure effect of the tumor.”2(p1117)
