Donald B. MacMillan Sr., 91, who lived in Brookfield, Kent and New Milford, died Oct. 11, 2009, surrounded by members of his large and loving family. He was the husband of the late Mary Elizabeth MacMillan for 47 years.

A designer, inventor, landscape architect and general contractor, Mr. MacMillan was born in Wilkensburg, Pa., May 7, 1918.

After graduating from Penn State University in 1938, he served as a Navy Air Corps pilot during World War II. After the war, he began his career in New York City, where he worked with noted industrial designer Norman Bel Geddes.

In 1950, he moved to Candlewood Shores in Brookfield and started a building and design company. He designed more than 300 houses, including many unique waterfront homes.

His experience and interest in aviation earned him employment at Sikorsky Aircraft, where he was instrumental in the design of the Black Hawk helicopter.

Mr. MacMillan was also active in local politics and served on the Brookfield Zoning Board and was one of the founding members of Candlewood Fire Company.

He is survived by three sons, Donald B. MacMillan Jr. and his wife Christine of Brookfield, Thomas MacMillan and his wife Kim of West Lebanon, N.H. and John MacMillan and his wife Julia of New Fairfield; three daughters, Amy Nargiso and her husband Steve of New Milford, Suellen Gearinger and her husband Mike of Goshen and Liza Haynie and her husband Terry of Brookfield.

Mr. MacMillan is also survived by more than a dozen grandchildren; several great-grandchildren; and a sister, Alice Dalton, of Newton Square, Pa.

Known to friends as "Mac" and to his grandchildren as "Pop Pop," Mr. MacMillian enjoyed being by his swimming pool, entertaining guests with his saxophone playing and storytelling.

Mr. MacMillan adored his pets, especially his late, beloved poodle, Rosie. A patriot, he raised his American flag every morning, and every year donned his dress whites and marched with the veterans in the Kent Memorial Day parade.

Calling hours will be today (Friday) at Lillis Funeral Home, 58 Bridge St., New Milford, from 5 to 8 p.m. with a brief memorial service at 7:30 p.m.

In lieu of flowers, contributions may be made in his memory to a charity of one's choice.
