Haggett's Garage embodied the transition from horse-drawn travel to cars in Wiscasset. In 1898, Haggett Bros. began selling hardware and plumbing services there, supplying the hardware used by livery stables, then the center of transportation. By 1910, cars had appeared in town, mostly brought by wealthy summer visitors, and the Haggetts recognized the opportunity. By 1911, they had added auto supplies to their hardware and plumbing business and opened a second business, "Haggett's Garage (auto)," listed in the directory under livery stables. World War I accelerated the popularity of automobiles. By 1920, state directories listed garages separately, though livery stables still appeared, and Wiscasset had "HAGGETT BROS. (auto), F. Burton Haggett, Proprietor." By 1930, the transition was complete: Haggett's Garage Co. offered sales, repair, and service stations, and livery now appeared under automobiles. At their peak, the Haggetts had two garages built back to back, with one entrance on Middle Street and one on Water Street and easy access between them. Arnold, Frank, Larry, and Harry Haggett kept Wiscasset running on all cylinders for almost 90 years.
