The Commonwealth Fund is a philanthropic foundation established in 1918 with the mandate "to do something for mankind." The fund in 1974 responded to a wide variety of ideas and proposals in the field of medical education and health care. A dominant goal of the fund has been to support and encourage medical centers in their efforts to develop effective systems for bringing health care to their surrounding communities. However, as in previous years, the fund's foremost interest was to strengthen medical education. In a related area, the fund continued its support for medical schools that are attacking, through expansion or modification of their curricula, those behavioral problems with roots in medicine that have awide impact on our society. The annual report describes in detail the aims of each project for which funds were appropriated including: strengthening medical education, health policy, social medicine, education for allied health professions, medical problems in human behavior, and international medical education. A report on the Harkness Fellowship program is included along with additional financial statements concerning the fund. (PG)
