Dean Winslow Freed ’43, who served on the Board of Managers in 1984, died in Duxbury, Mass., April 8. He was a perennial advocate of Swarthmore’s education and core values. At Swarthmore he earned a B.S. in mechanical engineering, was captain of the fencing team, and a member of Phi Sigma Kappa.

His career traced the technology curve from vacuum tubes at Sylvania Electric Products to leading-edge instruments and applications at EG&G Inc. of Wellesley, Mass., from which he retired as chairman and CEO in 1987. He was a director for several high-tech and energy-related businesses and president of the World Affairs Council of Boston.

An ardent patron and trustee of the Boston Symphony Orchestra, Freed was site liaison for the construction of Seiji Ozawa Hall at Tanglewood, beginning with architect selection in 1989 through its inaugural concert in 1994. He was also a benefactor and overseer of the Boston Ballet, Boston Lyric Opera, Museum of Fine Arts, New England Aquarium, WGBH, and Emerson Hospital, as well as a deacon at Trinitarian Congregational Church of Concord, Mass.

He greeted the ski season with zeal and traveled widely beyond the slopes to expand on his knowledge of history, arts, and world cultures. He is survived by his beloved wife Patrice Cain Freed, his daughters Carol Freed Bruml ’71, Kathryn Freed Simpson, and two granddaughters.
