Joseph C. Llewellyn was an architect active in the Chicago metropolitan area from 1892 – 1932, who specialized in school design and construction.  Llewellyn, though hardly a household name, was at one time a leading figure in regional and national architecture organizations.  He became predominantly known in architectural circles for his school designs, particularly in secondary education (high schools).  Unfortunately, Llewellyn’s contributions have been mostly ignored over time, though not forgotten.
