The gravestone for Louis H. Sullivan, in Graceland Cemetery in Chicago.

Louis H. Sullivan (September 3, 1856 – April 14, 1924)

“The work the master did may die with him—no great matter. What he represented has lived in spite of all drift—all friction, all waste, all slip—since time began for man. In this sense was Louis Sullivan true to tradition—in this sense will the divine spark, given to him from the deep centre of the universe and to which he held true, be handed on the fresher, more vital, more potent, enriched a little, perhaps much by the individuality that was his.”

—Frank Lloyd Wright in “Louis Henry Sullivan: Beloved Master” The Western Architect June 1924.
