John Albert Green Sr., a retired Baltimore City Public Schools director of facilities who was active in the Prince Hall Masons, died of kidney disease July 3 at the University of Maryland Medical Center. The Pikesville resident was 92.

“John was an outstanding public servant,” said former Baltimore Mayor Kurt L. Schmoke. “I worked closely with him to help address problems regarding housing. I would also see him and his wife in church at Bethel AME. John was very much involved with improving the quality of life for people in the community.”

Born in Baltimore, Mr. Green was the son of Roy Green, a chauffeur and real estate salesman, and Constance Payne, a Baltimore City schools teacher and department head at Calverton Junior High School.

As a child, he moved with his family to Hoes Heights, an African-American neighborhood near Roland Park. He attended Enon Baptist Church.

“Because of segregation, John could not attend the neighborhood schools and attended Booker T. Washington Junior High School and Frederick Douglass High School,” said Michell L. Morton, his wife’s niece who prepared the family obituary.

He earned a Bachelor of Science at Morgan State University and later earned a master’s degree in public administration, also at Morgan. Mr. Green also continued his graduate studies at Temple University in Philadelphia. While a college undergraduate, John married the former Barbara “Babs” Baden. They later divorced.

In 1952, he joined the Army as a lieutenant and served during the Korean War. “Even as an officer in the Army, he faced prejudice and discrimination. After leaving the military, Mr. Green became a physical education teacher for the Baltimore City Public Schools system.

He later married Mary Green, and they had two sons.

Mr. Green later left the school system to join the old Model Cities Program and later the Urban Service Agency, which were created as a result of the federal “war on poverty” legislation in the 1960s. He worked to bring city services into communities through neighborhood centers.

In 1985, he married Grenda Louise Green.

He served on the usher board and the board of trustees. He was also a trustee emeritus.

He was a member of the Baltimore Alumni Chapter of Kappa Alpha Psi Fraternity. He belonged to the Prince Hall Masons and Committee X-71.

Survivors include his wife, a retired Baltimore City Finance Department bureau chief and project manager; two sons, Lance Green and John Green, both of Baltimore; a stepson, Darric Boyd of Ellicott City; a niece, Jodi Thomas of Baltimore, whom he considered a daughter; and three grandchildren.
