Papers document Schild's career at the Carnegie Institute of Technology (1946-1957) and the University of Texas (1957-1977), with most of the material from his years in Texas. Some student course notes from his doctoral studies at the University of Toronto are included. The papers largely concern his research on relativity and gravitation, including work on foundations of relativity, quantization, algebraically special solutions, and conformal techniques. His later research dealt particularly with Fokker action principles and string models of particles. There are notes, manuscripts, and correspondence relating to his book Tensor Calculus (1949), written with J. L. Synge. Schild's work in the founding and administration of the UT Center for Research in Relativity Theory and the Texas Concerence on Relativistic Astrophysics is represented. There are also records of his consulting work with Gulf Research and Development. Correspondents include P. A. M. Dirac and L. Infeld. Included are correspondence, notes and drafts for publications, seminar papers, lecture and teaching notes, grant proposals, literary productions, reprints, photographs, and a sound recording.
