Thomas Mulholland was the director of the New York offices of the NCWC's Bureau of Immigration, and a close friend of Bruce Mohler. Mulholland spent much of his time at Ellis Island, helping new immigrants navigate the entrance process. He was active in lobbying for changes to immigration policy, testifying before a Department of Labor committee in 1934 about the problem of family separation due to the national origins quotas. Mulholland was also dedicated to securing aid and entrance into the U.S. for German Jews fleeing persecution in the 1930s, working closely with Bruce Mohler to rally support for German-Jewish immigration.
