Donald Hill died Oct. 29 at his beloved home in Oak Bluffs. He was 94.

Born in West Hazleton, Pa. to Wilson and Eva Hill, Donald attended Penn State University and earned a degree in chemical engineering in 1948. He served in the Army at Fort Dix between 1950-1952.

During his years of service, Donald met and married the love of his life, Mary Ellen LaDow. They were married for more than 70 years. He and Mary Ellen were long-term residents of Woodbury, N.J. and summer residents of Martha’s Vineyard. After retiring from Mobil, Donald designed and renovated the family home on the Island, moving there full time in 1991.

Donald had a successful career with Mobil Oil Company, starting in Paulsboro, N.J., then New York city, and, later, in Fairfax, Va.

He had a puzzle-loving mind, a bucket hat for every occasion and a list for everything. He taught himself to swim in Lagoon Pond with a Red Cross book he had checked out of the library, and he later learned how to sail in a similar way. He loved nature and taught his family to row, canoe, back up a trailer and pitch a tent. He introduced them to the Island, a place that they all treasure for its uncommon beauty.

Donald loved his wife and family dearly and was incredibly proud of his children, grandchildren and great-grandchildren.

He is survived by his devoted wife, Mary Ellen Hill; his children and their spouses: Elizabeth and Norman Lehrer, David and Kelly Hill, and Mary and Jim Long; his grandchildren Emily Lehrer Pierce, Benjamin Lehrer, Miranda Hill Jacob, Michael Hill, Megan Long and Delaney Long; and his great-grandchildren Oakland Hill and Julien Lehrer.

He was predeceased by his sisters, Doris Hill and Gladys Hill Sachs.

Donald will be remembered as a thoughtful, logical, and kind man who served as Lagoon Pond treasurer for many years and as a tax aid and Hospice volunteer. He belonged to the 1st and 3rd Club and was a member of the United Federated Church of Edgartown.

A private service is being planned. Visit www.chapmanfuneral.com for online tributes and information.
