The daughter of Morris Loitman and Fannie (Castleman) Loitman, Jennie (Loitman) Barron was born in Boston, Mass., on October 12, 1891. She attended Boston University (A.B. 1911, LL.M. 1914, honorary LL.D. 1959) and had a private law practice in Boston, 1914-1918, with her husband, Samuel Barron, Jr., 1918-1937. During this time she was elected to the Boston School Committee (1926-1930). The first woman in Massachusetts to present evidence to a Grand Jury and the first to prosecute major criminal cases, JLB in 1937 was also the first woman judge appointed for life to the Municipal Court in Boston, and in 1959 to the Superior Court in Massachusetts. She had married Samuel Barron, Jr., in 1918; they had three daughters: Erma (Barron) Wernick, Joy (Barron) Rachlin, and Deborah (Barron) Blazar, who died in 1956.
An organizer and first president of the Women's Suffrage Association of Boston University, JLB spoke at suffrage rallies in three states, was active with the League of Women Voters, and worked for the passage of laws to enable women to serve on juries in Massachusetts, and to provide equal guardianship rights for mothers. She was a delegate from the National League of Women Voters to the National Conference on Uniform Laws Regarding Marriage and Divorce (1930), and to the Mid-Century White House Conference on Child Welfare (1950). She lectured widely, in the United States and abroad, on juvenile delinquency and crime, and in 1960 was chosen to deliver the Independence Day Oration in Boston.
JLB was active in numerous professional, charitable, and civic organizations, including Beth Israel Hospital, Combined Jewish Philanthropies, Massachusetts Association of Women Lawyers, American Association of University Women, Hadassah, and Boston University. She was the recipient of many awards and citations, including National Woman of the Year (Boston Business and Professional Women's Club, 1954) and National American Mother of the Year (American Mothers Committee, 1959).
