Ruth Green was fondly referred to as the "First Lady of Larchont, NY". For nearly 40 years her volunteer work within the community was dedicated to the youth of the area through her service to Little League, the Babe Ruth League, and thirty-seven consecutive years of the Larchmont Parks and Recreational Commission. She was the Founder and Life Officer of the Humane Society, Vice-President of the local Community Chest and United Way, and activities on behalf of the Democratic Party, League of Women's Voters and every worthwhile charity in the town.
She founded the Larchmont Babe Ruth League in 1957 to "keep the boys occupied during the summer recess" and remained actively involved in it. She pursued the funds and convinced the city that they needed a ball field for the boys and successfully completed the establishment of a ball field which was later named "The Ruth Green Field".
Mrs. Ruth Green was inducted into the Babe Ruth League Hall of Fame in 1974.
