The University of Kansas School of Medicine depends on private gifts and bequests for many of its activities and functions. Grants from national foundations and agencies of the federal government are supplemented by gifts from individuals, often donated as memorials to or in honor of friends and relatives. The Kansas University Endowment Association maintains all funds separately, and many bear the names of the donors or of the persons honored or memorialized. Donations to the Endowment Association are used solely for the purposes designated by the donor without deductions for administrative costs or overhead. Endowment funds finance student loans, lectureships, scholarships, professorships, fellowships, and acquisitions for the Medical Center libraries. They also are used for general medical research and for special research in such fields as cancer, heart disease, and problems of aging. Both loan funds and scholarship funds benefit medical students. Funds received for scholarships are invested so that the income provides scholarships indefinitely. Both long-term and short-term loans are available. Long-term loans become payable one year after graduation. Short-term loans become payable within 90 days of issue.
