Further experiments in the potential for hybrid structures of iron and brick came in the early work of Adler & Sullivan. Often seen as less mature prelude to their more synthetic work of the 1890s, five major buildings executed between 1880 and 1884—the Borden, Rothschild, Jewelers, Revell, Troescher, and Ryerson—demonstrated their developing interest impressive skeletal masonry structures.
