“Ruskin worked for DuPont for 28 years in Plastics Research, specializing in ionic polymers. He authored several publications, including two book chapters on ionomers. After retiring in 1985, Ruskin pursued his lifelong interests in gardening, sailing, poetry, books, music, and cooking. He enjoyed spending time with his wife, children, and his grandchildren, especially at the family vacation home in Chatham, Mass.

His last chemistry demonstration for his grandchildren, just a few months before his death, was ‘the cry of tin.’ ”—Kim Longworth, daughter
