showing plaster models of proposed terracotta gravemarkers. (Courtesy, Columbia
University, Avery Architectural and Fine Arts Library, Columbia University

were made by the New York Architectural Terracotta Company, working at the
request of a Mr. Henry Hiss, from Woodlawn Cemetery, New York, and date
from 1915. It is not clear that the New York company pursued the idea any
further, though markers had long been made informally by many firms.
