August Charles Fruehauf (1868–1930), an American blacksmith and carriage builder who invented the tractor-trailer, a truck with the cab and engine separate from the main body of the truck. Fruehauf developed the tractor-trailer after, in 1914, a local lumber merchant asked him to build him a “thing to hitch to my Model T Ford that will take my boat to the lake". The trailer was so successful that the merchant had Fruehauf build similar haulers for his lumber, which Fruehauf came to call "semi-trailers." In 1918, Fruehauf incorporated his semi-trailer manufacturing company forming the Fruehauf Trailer Company. With the subsequent growth in automotive technology and expansion of the highway system, semi-trailers would become the dominant means of moving goods over long distances.
