This collection contains all the official records the trust established for the benefit of the Moore School of Electrical Engineering. The first two series contain the minutes and supporting papers in the form of correspondence and reports used for the meetings of the trustees from 1927 to 1977, 1989 and 1990. The Alfred Fitler Moore Estate series contains legal documents and correspondence relating to the duty of the trustees in reporting their actions to the Philadelphia Orphans' Court which has jurisdiction over the trust primarily from 1923 to 1977. It also includes several published agreements between the trustees of the will of Alfred Fitler Moore and the University of Pennsylvania. The general file series contains primarily financial records, such as audits and investment reports. There is also correspondence relating to the expenditure of the trusts funds and assets for the Moore School, particularly the Electromagnetic Wave Research Laboratory and Education Center near Valley Forge, Pennsylvania, the Graduate Research Center, and the X-Ray Laboratory Fund.
