Abstract：This opening session marks the legacy of Bill Hillier at this, the 25th year anniversary of the first space syntax symposium. Given the immeasurable range of influences Bill’s ideas have had on the space syntax community, this session was designed around a small number of his past PhD students, each of whom spoke for up to 10 minutes on some aspect of their work with Bill, and how his ideas have guided them since then. The session was chaired by Margarita Greene, with short talks from: Frederico de Holanda, Sophia Psarra, Ruth Conroy Dalton, Vinicius M. Netto, Tao Yang. The session was organized by Laura Vaughan, John Peponis, and Ruth Conroy Dalton. The texts from all presenters from this opening session are presented in this paper.
