Correspondence, photographs, printed matter, personal and project papers documenting the career of the engineer Egidio Alfred Picardi. His achievements as a civil engineer included the design of the solar telescope at Kitt Peak National Observatory in Tucson, Arizona and tenure as chief engineer at the Chicago office of Skidmore, Owings, & Merrill, where he introduced the shell structure concept in high-rise building design as originally proposed for the John Hancock Center. Picardi left SOM in 1967 for Perkins & Will, where he helped design the Standard Oil of Indiana building in Chicago (now the Aon Center).
