In 1938, after eight years of experimentation, Nestlé launched Nescafé, a powdered instant coffee superior to previous efforts. It was produced by spraying brewed coffee into heated towers, where it turned to powder almost instantly. The venerable Swiss firm had been founded by Henri Nestlé in 1867, when he invented an infant-feeding formula. With subsidiaries for its chocolate and confectionery products already in place all over the world, Nestlé was ideally situated to promote its new instant coffee, while the advent of World War II provided the perfect American market when the US military bought all the instant coffee it could.
