First Publication on Solving the Franklin Cipher BERKEL, Ernest. The Benjamin Franklin Cipher. "Deciphered August 8, 1935, by Ernest Berkel, Mt. Clemens, Mi." 11"x 8.5", 4 leaves. CARBON COPY. Here Berkel claims to have discovered the cipher source for the Franklin cipher he evidently did not discover the French text on which the cipher was based, but rather stole the credit for the discovery by the great William (Wolf) Friedman. Stapled leaves. Provenance: this was a gift from Berkel to the Library of Congress. The Birkel gift is annotated by a contemporary Librarian's hand; there is a small (10mm) perforated "LC" in the front cover and a LC rubber stamp on the rear page. GOOD copy, with dusting and an old horizontal fold shadow at center. Rare. [++] It is reported in Betsy Rohauly Smoot's book, "Parker Hitt: the Father of American Cryptology" (p 177) that Berkel had worked on the famous cipher for five years and then used a connection of his with the US Army Signal Office who ordered the preeminent William Friedman to solve the cipher, which he evidently did. According to Smoot, Berkel "publicly took credit for Friedman's work". Berkel published "his" findings in the December 1935 issue of Cryptogram (the journal of the American Cryptogram Association). According to WorldCat this article ran on pp 1, 2, and 5, which makes it about the length of the paper being offered here. I suspect that this and the published account are the same piece of writing. NO COPIES of this work are found in WorldCat. [++] ("William Frederick Friedman (1891 1969) was a US Army cryptographer who ran the research division of the Army's Signal Intelligence Service (SIS) in the 1930s, and parts of its follow-on services into the 1950s. In 1940, subordinates of his led by Frank Rowlett broke Japan's PURPLE cipher, thus disclosing Japanese diplomatic secrets before America's entrance into World War II."--Wikipedia According to another source Friedman was chief cryptanalyst for the War Department and led the SIS for 25 years. I can find very little on Mr. Berkel. Oddly enough, the Berkel paper uses a paper with the federal watermark of the American Eagle so at least the paper he used was from the U.S. Government, which may or may not mean that Berkel was a federal employee.…
