Gardner-Serpollet was a French car manufacturer in the early 20th century that specialized in steam-powered vehicles. Léon Serpollet, the inventor of the flash boiler, perfected the technology in the late 1800s and produced his own cars under the Serpollet and Gardner-Serpollet brands until his death in 1907. The company was known for producing innovative and high-quality steam cars that were popular with wealthy customers.
