Thornton “Thorny” Calef Lockwood passed away peacefully on Dec. 20, 2024 in Brunswick at the age of 93.

Born on March 17, 1931 in Mansfield, Ohio, he was the second son of Edwin Hoyt Lockwood II and Margaret Coe Lockwood.

Thorny was a descendant of Josiah Bartlett, the New Hampshire signer of the Declaration of Independence, and was a first cousin of Benjamin Franklin, eight times removed. His family tree included a number of the first settlers in New England, including some in the towns of Kittery, Hampton, Newbury, Nantucket, Deerfield, Wethersfield, Norwalk, New Canaan and New Amsterdam.

He and his older brother, Edwin Hoyt Lockwood III, attended public schools in Mansfield, Ohio, and both were paper delivery boys for the Mansfield News Journal and the Cleveland Plain Dealer.

He attended Roger Ludlowe High School in Fairfield, Connecticut, and graduated from Warren Harding High School in Bridgeport, Connecticut in 1949. He graduated with a BA in psychology from Yale University in 1953, and from Columbia University in 1955 with an MBA in marketing. After a short stint at D’Arcy Advertising in New York City, he entered the armed forces and was stationed for two years at Fort Williams in Cape Elizabeth, Maine with the U. S. Army. Here he was responsible for administering the Armed Forces Qualification Test. At this time he formed a lifetime affinity for the lighthouses and forts on the Maine coast.

On July 21, 1956 he married Mary Lenora “Lee” McGinn in the chapel at Dow Air Force Base in Bangor, Maine. Lee was a Wellesley College and Columbia Business School graduate, and a native of Bangor. The couple met over a punch bowl at a Columbia Business School dance in 1955. Lee and Thorny lived in Tenafly, and Demarest, New Jersey. During this time, they relocated temporarily for two enjoyable three-year work assignments, one in London and the other in Birmingham, Michigan. They spent several weeks each summer at their cottage in East Boothbay, Maine, visiting with family and friends, looking out over Linekin Bay, taking a dip in the pool, motoring around the Boothbay Harbor waters, and depleting the lobster stocks in the area.

For 40 years, Mr. Lockwood worked in marketing and advertising, becoming head of research and a VP at Benton & Bowles in London and New York; at Chemical Bank; at J. Walter Thompson in Detroit; and at AT&T. During his career he pioneered the development of leading edge technologies for measuring the effectiveness of television commercials and advertising campaigns.

Mr. Lockwood was a frequent speaker and participant at seminars and meetings on advertising, marketing research, and brand equity. He was an active leader in research associations, serving as chairman of the Conference Board’s Market Research Council, president of the Detroit Chapter of the American Marketing Association, and a director of the Advertising Research Foundation. He was chairman of the ARF’s Creative Development and Evaluation Council for more than 10 years.

After retirement from corporate life in 1996, Mr. Lockwood became president of his own consulting service, The Lockwood Group, and was elected a Fellow of Davenport College at Yale.

In 1997, he joined the Descendants of the Signers of the Declaration of Independence, and served as secretary, chairman of the Biography Project, and chairman of the Brochure Committee. He gave numerous presentations on the Legacy of the Declaration of Independence. In 2011, he received that Society’s highest honor, the Patriot Award.

Music played a big part in his life. He was a boy soprano soloist in his church choir in Mansfield, and later a member of the Glee Club, the Madrigal Group and the Baker’s Dozen at Yale. At Columbia, he formed his own folk group, the Mountain Lions. More recently, he traveled and performed with the Yale Alumni Chorus on concert tours in Russia, Europe and South America. He was a big opera fan, and was particularly partial to those of Giuseppe Verdi.

During the last eight years, Thorny and Lee’s numerous caregivers played a significant role, not only in their lives, but also in their family's life. And they, too, have become and will remain family.

He is survived by, a daughter, Carolyn Lockwood, of Bath; a son, Thornton Lockwood Jr., and his wife, Deanne Moore, of Cheshire, Connecticut; three grandchildren Nicholas, Bartlett and Paxson. He is also survived by his sister-in-law Lynne McGinn, of Ocean Ridge, Florida; his nieces and nephews, Stacey McGinn Smith, of Bar Harbor; Joshua McGinn, of San Francisco, California; Sepp McGinn, of Orrington; and Christian McGinn, of Parkman; and numerous grand-nieces and grand-nephews.

He was predeceased by his beloved wife of 67 years, Lenora McGinn Lockwood; his parents, Margaret Coe and Edwin H. Lockwood II; and his brother Edwin H. Lockwood III.

A Mass of Christian Burial will take place in the spring in Bangor at St. Mary’s Catholic Church. Interment will follow at Mount Pleasant Catholic Cemetery in Bangor. Funeral Arrangements are by Daigle Funeral Home, Bath.
