Soundex Hollerith

Soundex - Wikipedia, the free encyclopedia: "Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for names with the same pronunciation to be encoded to the same representation so that they can be matched despite minor differences in spelling[1]. Soundex is the most widely known of all phonetic algorithms and is often used (incorrectly) as a synonym for 'phonetic algorithm'. Improvements to Soundex are the basis for many modern phonetic algorithms"

Soundex was developed by Robert Russell and Margaret Odell and patented in 1918^[2] and 1922^[3]. A variation called American Soundex was used in the 1930s for a retrospective analysis of the US censuses from 1890 through 1920. The Soundex code came to prominence in the 1960s when it was the subject of several articles in the Communications and Journal of the Association for Computing Machinery (CACM and JACM), and especially when described in Donald Knuth's magnum opus, The Art of Computer Programming.

The National Archives and Records Administration (NARA) maintains the current rule set for the official implementation of Soundex used by the U.S. Government.^[1] These encoding rules are available from NARA, upon request, in the form of General Information Leaflet 55, "Using the Census Soundex".
