Anna Baldwin developed an early suction milking machine that paved the way for a revolution in dairy farming practices. Though her invention was important, contemporary industrial milking machines differ from Baldwin's design.
In 1878, a New Jersey woman named Anna Baldwin developed a suction milking machine that made it possible for dairy farmers to extract milk from their cows with a method more efficient than hand milking. Baldwin patented her machine, but most of the glory in this area goes to Carl Gustav de Leval, a Swedish inventor who developed the first milking machine to gain wide commercial success, paving the way for contemporary industrialized dairy farming. Baldwin's fame is largely related to the trailblazing nature of her invention rather than its success, though her accomplishment is nonetheless impressive and is part of the zeitgeist of the Industrial Revolution.
