Yes, it's "Thesaurus Day".
Born in London of a Swiss Calvinist family.
Pronounced UK: /ˈrɒʒeɪ/ US: /roʊˈʒeɪ/ (saith Wiki).
Active in the world of science during his life, but now remembered
almost entirely for the Thesaurus (1st ed. 1852).
I once tried making a "thesaurus" of Proto-Polynesian -- well, a
vocabulary arranged by semantic fields, with a more or less hierarchical structure. You can see a version of it here:

I found it a useful exercise, but was never satisfied with the overall
scheme -- probably just because the actual mental lexicon is not in fact organized that way. But something like this is good for eliciting
vocabulary from native speakers, where an alphabetical-order approach is counter-productive.
