Quick Summary

Johannes Grubenmann, along with his brother Hans Ulrich, was a Swiss carpenter and bridge builder in the 18th century. They are credited with designing and constructing bridges that ingeniously combined arch and truss principles, allowing for longer and stronger timber bridges than previously possible.1

Their most notable work includes a bridge over the Rhine at Schaffhausen (1755) and a bridge at Reichenau. In 1758, they began work on the Wettingen bridge, which featured a significant arch-truss design. Although these bridges were later destroyed, their innovative designs influenced bridge construction across Europe.1
