It is almost certain that Loos would have read Sullivan's essay prior to designing the Chicago Tribune Tower. This essay appeared in Lippincott's March 1896 issue, just as Loos was leaving the United States to return to Vienna. Sullivan had also sent a copy of the essay to Loos in March 1920, two years prior to the formation of his design of the Tribune Column, in the hopes of finding a European publisher. 103 In addition to Sullivan's influential essay and the Columbian Exhibition, where he would have seen numerous classical buildings and the large obelisk at the fair, there were also several American structures that may have influenced his design, including the sixty-nine-foot ancient Egyptian obelisk, Cleopatra's Needle, dating from ca. 1475 BC, which had been moved to the city and erected in Central Park in February of 1881 and the Bunker Hill Monument. It was the influence of American structures, particularly the Bunker Hill Monument, that directly influenced his architectural designs when he returned to Austria.
