Philanthropist Jackson Stephens is giving 1.5 million dollars to the University of Arkansas for Medical Sciences for a second endowed chair in geriatric medicine. The gift will be matched by funds the Donald W. Reynolds Foundation has already committed. It is Stephens` second gift to the medical school`s department of geriatrics. In 1999, Stephens contributed 1.5 million dollars for a chair held by Doctor David Lipschitz. Stephens has also given 48 million dollars to UAMS for the Jackson T. Stephens Spine and Neurosciences Institute, which opened in April.
