  == main article needs a chronology ==  When, exactly, did the Shannon-Fano coding come to be called that, and not something else?  Are there any months and dates that can be assigned to the discovery of the Shannon-Fano coding scheme?  If the discovery cannot itself be dated, when was the Shannon-Fano coding scheme first published in hardcopy form?  If it was never published in hardcopy form, when was it first disseminated electronically?
