Croizat was a pioneer in the automobile industry of northern Italy; after licensing motor designs from
Peugeot, he founded Automobili Peugeot SA Brevetti to produce new automobiles under the brand
Peugeot-Croizat. The company used modified versions of the Peugeot designs, and operated from 1905 to 1907. Croizat was also a dealer for
Rambler bicycles. Croizat also was an investor in early oil refining efforts in Italy, and owned the Piano d'Orta oil refinery. ==Personal life==
