Alfonso Bialetti, born in 1888 in Piedmont, spent a decade in the French aluminum industry when the metal was still a serious material for aviation and rail. Back in Crusinallo in 1919 he opened a shell foundry, casting aluminum in reusable steel molds that gave the smooth, precise threads a pressurized pot needs. His first attempt carried the name Triple Rapid Miracle 900, and he refined it alongside other European designers. The episode explains the physics: steam in the lower chamber pushes boiling water up through the coffee and into the top. The eight facets are structural, stiffening soft aluminum against warping, giving a grip on a hot wet pot, and shedding heat quickly off the flame.

Between 1934 and 1940 Bialetti sold about 70,000 early versions hand to hand at Piedmont’s outdoor markets, while Otello Amleto Spadini patented a competing design in 1937. World War II diverted aluminum to the military and dried up coffee supplies. In 1946 his son Renato took over, cut nearly every other product, and bet the company on the Moka Express, which the record says Alfonso finalized in 1950. A factory in Omegna followed in 1956, along with television ads, Milan billboards, and a giant monument of the pot. Production passed 220 million by 2001 and later topped 330 million, earning a Guinness World Record.

• Before the moka pot, espresso meant expensive bar machines that needed trained operators.
• In 1953 illustrator Paul Campani created the mascot of a mustachioed little man, modeled on Renato himself.
• His raised index finger is the Italian gesture for ordering another espresso.
• The mascot doubled as an anti-counterfeit mark against copycat pots.
• Alfonso died in 1970, and the brand now sits under Bradshaw International.
