“…The accumulators were very soon enhanced with a manually operated accumulator coupling to enable the tabulator to get subtotals and totals as well as grand totals. 11 Adding was now the prime process with the tabulator. The speed of the 1908 Hollerith Vertical Sorter was 15,000 cards per hour, and the tabulator operated with 9,000 cards per hour during uninterrupted processing.…”

“…These made the use of time-differentiated electrical impulses essential. 22,23,11 It was then essential to have 12 punch positions in one card column that represented the digits nine to zero, with the nine at the lowest punch position. The extra two positions at the top of the card were not initially used.…”

“…The standard model of the DE-HOMAG Tabulator D 11 is a very remarkable punched card machine described in detail in another issue of the Annals. 11 Because a population census needs counting, the D 11 was made a counting machine. All the advanced functions of the normal D 11 had been removed, for example, multiplication, division, direct subtraction, and some other functions and features.…”

“…2,3,4,5,6,7,8,9 But a great effort has still to be doneespecially technical development has to be researched if we are to understand the application of this technology and the interaction between its application and developments, including its social influence. 10,11 This article is intended to give a systematic overview of punched card technology in census work. I initiated my research for this article in 1984 when Götz Aly and Karl Heinz Roth published the book Die restlose Erfassung (The Total Registration) and Rudolf Lindner et al published the book Planen, Entscheiden, Herrschen (Planning, Deciding, Ruling).…”

This article is designed to provide information regarding the development of punched card technology for use in both census and commercial applications. After describing the different types of technology and how they were used, this article provides a detailed description of census requirementsand, in particular, the German censuses of 1925, 1933, and 1939-in an effort to counter arguments that German authorities used the results of these censuses during the Holocaust period. Extensive references are provided to enable others to have access to information from that era.
