revolution in the 1950s, Tantlinger developed much of the early technology that made modern container shipping possible while at Fruehauf. After its initial order of containers from Brown Trailer,
Sea-Land switched to containers made by the Strick division of the Fruehauf Trailer Company. Fruehauf had been one of the dominant players in building truck bodies and trailers for a long time, and, as already described, had previously innovated in the design and construction of the early commercial semi-trailers. President Roy Fruehauf was impressed with the idea of containerization, so in addition to manufacturing containers for
Sea-Land his company agreed to make the trailer chassis that were needed, and also to provide financing to Sea-Land for the purchase of these containers and chassis.
In 1958 Tantlinger left
Sea-Land and became chief engineer at Fruehauf, where he continued to work with containers. More importantly, over the years he played a key role in the process of container standardization, working extensively on a committee of the American Standards Association (ASA) and later being critically involved with the ISO's efforts. His designs included the corner casting and

He married Marjorie Cunningham. They had a daughter, Susan Tantlinger, and they later divorced.][
In the 1950s, Tantlinger persuaded McLean that shipping containers should be built so they could be separated from a chassis, with strong corner posts and built so they could be stacked on top of each other.
