Daniel W. Dietrich II, a philanthropist who gave generously to Penn’s Institute of Contemporary Art (ICA), died on September 1 at Paoli Hospital. He was 73 years old.

Mr. Dietrich earned his bachelor’s degree in art history from Hamilton College. He was heir to a family conglomerate that included Luden’s cough drops, where he once served as vice president. He had served on ICA’s board of overseers beginning in 1969 and became an emeritus overseer in 2014. Earlier this year, Mr. Dietrich gave $10 million to ICA, doubling the institution’s endowment (Almanac May 12, 2015). The gift supports ICA’s artist-centered mission and guarantees multi-year curatorial research and exhibition development opportunities.

Mr. Dietrich is survived by his partner, Deborah Ullman, and three sons, William S. Hildreth, Daniel W. III and Adam.
