Carburetor
The first carburetor was invented by Samuel Morey in 1826. The first person to patent a carburetor for use in a petroleum engine was Siegfried Marcus with his 6 July 1872 patent for a device which mixes fuel with air.
Eduardo Weber
His work to remedy high gasoline prices resulted in the first "Weber carburetor", a "sidedraft, twin-choke ... bolted to a Weber designed overhead-valve/supercharger conversion for the 501 Fiat". In 1923 he established the "Fabbrica Italiana Carburatori Weber" company, which under his leadership became supplier to Fiat mass-produced cars as well as small-volume Alfa Romeo and Maserati racing cars.
