For over half a century, Weidlinger Associates has stood for innovation in structural and civil engineering and applied mechanics. The firm owes this tradition to Paul Weidlinger and the distinguished group of partners he recruited to join him: Mario Salvadori, Melvin Baron, Matthys Levy and Herbert Rothman. The partnership served national and international architects and also became widely recognized for the preservation of long span steel bridges and computer analysis of military structures.
