Sorry I didn't see this notice until just now, seems that the comment notifications were broken for me. Here's some information on IBM's involvement in World War II: https://en.wikipedia.org/wiki/IBM_during_World_War_II
'His grand design for 1943 was a locator file in which would appear a Hollerith alphabetic punch card for each evacuee. These cards were to include standard demographic information about age, sex, education, occupation, family size, medical history, criminal record, and RC location. However, additional data categories about links to Japan were also maintained, such as years of residence in Japan and the extent of education received there... The punch card project was so extensive and immediate that the War Relocation Authority subcontracted the function to IBM.'
