==History== The formicarium was invented by Charles Janet, a French entomologist and polymath, who had the idea of reducing the three dimensions of an ant nest to the virtual two dimensions between two panes of glass. His design was exhibited in the 1900 Exposition Universelle in Paris. Janet's invention was recognized by his promotion to Chevalier (Knight) of the Legion of Honour, but he did not obtain a patent for, nor attempt to market his creation.
