Porsche’s engines were designed from the onset to be simple, with two valves per cylinder and hemispherical heads, no water to leak or hoses to break, a single overhead cam per side and chain drive. The longevity has lasted: Porsche claims that 70 percent of all its cars are still on the road.
The horizontally mounted fan at the top of the engine, fan blades like a seashell, pumps air en masse downward to the cylinder head, whose fins extract heat away and out from the engine.
Instead of separate water and oil channels, Porsche enlarged the latter and ran lines to the front of the car, away from the heat in back. The result necessitated more oil than most water-cooled cars, but the payoff in simplicity was worth it. To match increasing power outputs, 911s eventually received dedicated oil coolers in the right front fender.

Autoweek says every manufacturer built air cooled engines, and sure, the Corvair, the Tucker, VW, Porsche, BMW Isetta, and who know what European car makers - Citroen, Fiat, and maybe Goggomobile? But, "every" car maker? Nah, I don't think so
Could the very first engines from Ford, GM, and Studebaker have been aircooled? Possibly. But that "every" is too far fetched for me to believe. I doubt Ferrari, Lamborghini, and other Italian car makers ever had air cooled engines.
Maybe "Once" is not meaning that they all had an air cooled engine, but rather, at a moment in history in the 1890s -1905, every car maker that there was, and there weren't many, built an aircooled.
