Author and lawyer
In 1938 published Shakespeare's maze further deciphered, and 'The Cypher in the Sonnets' (1940) and various other books on the Shakespearian theme (and thought that the true author was of Italian origin).
In 1943 published a solution to the Voynich Manuscript 'Roger Bacon's Cipher: The Right Key Found', based on the theory that it had been written by Roger Bacon. (This has since been disproved by the dating of the manuscript to the 15th century rather than the 13th.)
Another book was 'The Cyphers in the De Rerum Natura' (by Lucretius: Wikipedia page ).
