Luther Judson Glenn (November 26, 1818 – June 9, 1886) was a prominent Georgia lawyer, politician, Confederate officer during the American Civil War, and antebellum Mayor of Atlanta. He attended the University of Georgia where he was a member of the Phi Kappa Literary Society and graduated in 1841. He was married to Mildred Lewis Cobb, a younger sister of Generals Howell and Thomas Reade Rootes Cobb (Howell Cobb later served as Governor of Georgia). An attorney, Glenn represented Henry County in the state legislature as a Democrat before arriving in Atlanta in 1851. Six years later, he was elected mayor and served two consecutive one-year terms. He was the first mayor to appoint regular committees in council for the various functions of city governance: Fire, Streets, Finance, and so on.
