In 1940, census takers find Henry Hecksher, already using his assumed name, as a lodger in an apartment in New York.
The 29-year-old future CIA officer was living in the New University Court Apartments in Manhattan, staying with 70-year-old widow Emily Wilson, her son and another lodger from Norway. The census date of record was April 1.
