Claim: The Chemist who was never able to make any filament lamps and who commented on Darwin's theory of evolution was Adolphe Alexandre Chaillet(July 15, 1867 Paris – after 1914)
Evidence: Chaillet's light-bulb design involved flattening the elliptically-looped carbon filament coil set transversely to the longitudinal axis of the lamp, as well as flattening the end of the globe, or bulb at its tip end, parallel to the loops, so that the greatest intensity of light is thrown downward when the bulb is hung from the ceiling. 
In a newspaper article, he commented on Darwin's theory of evolution.
