Frank G. Keen Sr., longtime resident of Darien and Wilton and former teacher in Darien, died Jan. 15 at Norwwalk Hospital. He was 84. He had been living at the Wilton Meadows Home Health Care Center.

Born in Brooklyn, N.Y., on Nov. 13, 1926, Mr. Keen was raised in Darien by his parents, Frank H. and Alice Keen. He graduated from Darien High School in 1945 and served as a veteran in the finals days of World War II. He was awarded the World War II Victory Medal and a medal for the Army Occupation of Germany.

Recognized as a star athlete, he played on the Darien varsity football, baseball and boxing teams. He continued to play baseball and football in the Army and at Arnold College where he graduated in 1950 with a degree in education.

He played semi-pro ball and was invited to a try-out with the Brooklyn Dodgers but declined so he could serve his country in the Army. He was honored as an outstanding athlete by the Darien Old Timers Association.

Mr. Keen began his teaching career in a one-room school house in Vermont but returned to his hometown of Darien where he taught science at what was then Middlesex Junior High School for 34 years. During his career, he earned a master's degree in science from the University of Bridgeport and a sixth-year degree from St. Joseph's College. He was head of the science department at Middlesex and a member of the Leaders of American Secondary Education. He coached the school football, basketball and baseball teams for many years, retiring in 1988.

He moved his family from Darien to Wilton in 1965, where he lived the rest of his life. He spent his retirement years traveling the world with his wife, Lucille, and working on his many hobbies, including building model wooden ships.

Survivors include his brother, David, and his sister, Marjorie Bruno; three sons and their families: Frank Jr., his wife Sally, and their daughters, Adrienne and Marisa; Robert, his wife, Lori, and their son Brian; and David, his wife, Melodie, and their daughter, Danielle.
