What a contribution this man made!
We move goods all around the world using container ships. Keith Tantlinger figured all of this out – containers stacked upon each other in cargo holds.
From wikipedia: Working with Malcom McLean, who spearheaded the container ship revolution in the 1950s, Tantlinger developed much of the early technology that made modern container shipping possible. His designs included the corner casting and twist-lock systems found on every shipping container, the spreader bar for automatic securing of containers lifted on and off ships, and the ship-shore container transfer apparatus for the first cellular container ship. In the course of his professional career, Tantlinger was granted 79 United States patents, all related to transportation equipment. Many of his patents related to commercial highway freight trailers and transit buses.
