Blanchard was the inventor of two separate and distinct systems of stenography, the first of which he published under the title of
A Complete System of Shorthand. This was followed by the explanation of a more elaborate system in
The Complete Instructor of Shorthand. The method of stenography described in the second work was hardly practised, if praised in the
Historical Account of Shorthand, under the name of
James Henry Lewis. Several trials taken in shorthand by Blanchard were published between 1775 and 1791, including the trials of
Admiral Keppel and
John Horne Tooke. ==References==
