Seeley 1888 is the source of the names:
Seeley, H. G., 1888. "On the Classification of the Fossil Animals Commonly
Named Dinosauria," Proceedings of the Royal Society of London 43: 165?171.
In those days there was an active school of dino-thought that considered
ornithischians closer to birds than were saurischian dinosaurs, and the
ornithischian pelvis was considered a synapomorphy (to use more modern
terminology) that united Ornithischia and Aves.
