     Frank Lloyd Wright did not call himself an artist. He called himself an architect. But the buildings he

designed were works of art. He looked at the ugly square buildings around him, and he did not like what

he saw. He wondered why people built ugly homes, when they could have beautiful ones. 

     Frank Lloyd Wright lived from 1869 to 1959. When he was young, there were no courses in architecture,

so he went to work in an architect's office in order to learn how to design buildings. Soon he was designing

buildings that were beautiful.

     He also wanted to make his buildings fit into the land around them. One of the houses he designed is on

top of a high hill. Other people built tall, square houses on hills, but Wright did not want to lose the beauty

of the hill. He built the house low and wide.
