Frank Lloyd Wright was an American architect, interior designer, writer, and educator, who designed more than 1,000 structures, 532 of which were completed. Wright believed in designing structures that were in harmony with humanity and its environment, a philosophy he called organic architecture. One of Wright's goals was to make the "Prairie school", which was the design of a building, in the late 19th- and early 20th-century, which he did accomplish.
Abstract art was created at the cusp of the 20th century. It is an art style that breaks away from drawing art as it is represented in real life. Abstract art is about exploring form and color. One could even venture to say that it is artists drawing how they feel. Abstract art isn't about making perfect copies of real life. Sometimes, it isn't even about giving the impression of real life without all the little details. In fact, depending on the artists, abstract art became about the process itself. Representational would mean that you draw what you see. Abstract art is far from that concept.
