Eladio Dieste (1917 - 2000) was a Uruguayan engineer and architect who made his reputation by building a range of structures from grain silos, factory sheds, markets and churches, all in Uruguay and all of exceptional elegance. His buildings were mostly roofed with thin shell vaults constructed of brick and ceramic tiles. These forms were cheaper than reinforced concrete, and didn't require ribs and beams. In developing this approach, even in comparison with modernists the world over, he was an innovator.
