    An immigrant tile setter, Sam Rodia, has created a work of art in the Watts Towers in California which has been officially designated by the state as a historic cultural monument. In 1921, Sam started to build on his little lot, backed up against a railroad track in Watts, a small town near Los Angeles. He built for 33 years, without money and without tools beyond the simple tools of the tile setter and a window washer's belt and buckle. He built with any kind of materials he could find- pipe, angle irons, stone, steel, broken concrete, bottle caps, and railroad tie all held together buy cement. After the work was completed, it became a popular site for children until 1959 when the city decided it was a public menace and ordered it torn down. But artists saw in the work a stamp of genius and a committee was formed to save the Watts Towers. The city agreed to a stress tests and the towers passed the test. Sam Rodia leaves two legacies to those who work with concrete: a powerful faith in the remarkable qualities of this material and an astounding example of the high quality and permanency that can be achieved through careful and thoughtful use.

    After Thomas Edison constructed the first monolithic concrete house in 1908, many varieties of the original plan were seen in houses, apartments, and finally churches. In 1912, the American Sheet and Tinplate Company completed 14 buildings of monolithic concrete, costing something over $130,000 and houses for 74 families of workmen in its mills. The Edison plan for monolithic concrete construction was improved upon in the sectional forms used by the tinplate company. These forms and their accessories numbered 28,000 separate pieces and comprised the equipment for as many as 20 different styles of houses. Another attempt at monolithic concrete construction was initiated in 1911 when an entire church was built by casting concrete walls on the ground. On the foundation wall and on piles inside of the building lot a series of steel jacks were set. A platform was laid on the jacks and all door frames, window frames and other openings were positioned on this platform and concrete was placed around the openings. After 48 hours each wall was raised from the inside to its permanent vertical position by means of a gasoline engine. Not until World War I, when the increased demand for housing reawakened interest in monolithic construction, did builders again attempt to construct monolithic concrete houses. After the war, though, interest lagged again.
