The Fruehauf Trailer Company operated from 1914 to 1997 across the United States, Europe and Asia introducing such revolutionary inventions as hydraulic dump trailers, bulk tanker trailers, the automatic fifth wheel hitch and the shipping container in 1956.

“Over 1,000 inventions, 150 for the military alone, helped the Fruehauf Trailer Company attain the rank of 75th largest company in the world

DHM exhibition will feature photographs and company memorabilia from the family’s collection focusing on the key Fruehauf patents and innovations to the trucking industry. The exhibition inaugurates a new DHM gallery and will remain on view for the next nine months.

By the mid-1920s, trailer sales passed the million-dollar mark, and by the mid-1950s, Fruehauf had expanded into nine plants across the United States, Canada, Brazil and France. Along the way, the company secured hundreds of patents for trailer innovations, including the automatic coupling, hydraulic dump trailers and bulk tanker trailers. In 1956, Fruehauf even had a part in developing what we now know as the intermodal shipping container, designed for simplified shipping of goods on train, truck or ship.

After the company fell out of the family’s hands in the mid-1960s, Fruehauf began to diversify, eventually buying up subsidiaries such as Kelsey-Hayes. But by the 1990s, power struggles and financial problems within the company forced Fruehauf into bankruptcy, leading Wabash National to buy Fruehauf’s main U.S. business in 1997.
