Verneuil, Auguste

Verneuil, August Victor Louis (1856-1913) was a French chemist who reported his method for growing ruby in 1902. 

August Verneuil develops a process for making synthetic rubies... 

Thus, the flame-fusion process is a crucible-free crystal growth process for high-melting compounds, an economic process that allows control of nucleation and crystal diameter within a relatively simple apparatus, and was a signiflcant breakthrough achieved by Auguste Verneuil around 1900.
