The Martin Maloney Chemical Laboratory of The Catholic University of America was built in November, 1917. Maloney Hall was named for Martin Maloney, a papal marquis from Philadelphia, Pa., who gave $120,000 for the main building and $100,000 for the auditorium.
Malonery Hall underwent renovations and extensions in 1926. Currently, the building is being used as a chemical laboratory for the University. It houses the Department of Chemistry, classrooms, laboratories and an auditorium. When it was first built it served as a laboratory for Army researchers developing chemical munitions for World War I.
Maloney Hall is the laboratory where the chemical weapon Lewisite was first invented by Julius Nieuwland and later Winford Lee Lewis, with the help of CUA and Army researchers, developed it into a now-banned chemical weapon.
