Columbus native and 1939 mechanical engineering graduate Tom Hardy, 93, visited campus late last week to talk to members of engineering honor society Tau Beta Pi. Hardy is pictured with the concrete Tau Beta Pi Bent that he helped pour in the 1930s. Mississippi State is one of few universities that has a concrete bent in that style. The bent of a trestle bears the load of a bridge and signifies the society's principle of integrity and excellence in engineering.
