Note 433 — CHAPTER 21 THE FIRST GENERATION IN AUSTRIA, HOLLAND, AND SCANDINAVIA

The use of aluminium in architecture became widespread only some forty years later, it should be noted, although it had supplied the cap of the pyramid with which T. L. Casey finally completed the Washington Monument as early as 1884—its first use in architecture. In the nineties Thomas Harris already foresaw its great importance in building; see his Three Periods of English Architecture, London, 1894.
