Birthing Dataviz: Steven Heller on the Isotype archive

Steven Heller wrote about my research for Design Observer: the W.E.B. Du Bois charts, the Isotype book in progress and the archive behind it, with 57 Isotype books, 19 by Rudolf Modley and more than 180 research papers. He singles out the Telefacts, the syndicated Isotype charts I found in old newspapers.
