developed space frames based on tetrahedral geometry, primarily for nautical and aeronautical engineering. He invented the tetrahedral truss.

Max Mengeringhausen developed the space grid system called MERO (acronym of MEngeringhausen ROhrbauweise) in 1943 in Germany, the first use of space trusses in architecture. The commonly used method, still in use, has individual tubular members connected at node joints (ball shaped) and variations
