Krueger retired to San Antonio, Texas, where, in February 1946, he bought a house for the first time. Because of a large income tax bill left over from the war, he was unable to buy it outright and so some of his friends established the Krueger Fund Committee, which paid for much of the house. In retirement, Krueger was involved in a number of charity and community organizations, including the United Service Organization, the Red Cross, and the National Foundation for Infantile Paralysis, and he served as director of civil defense for San Antonio and Bexar County.[85]
