In 1968, artist Joseph Louis Young installed a 16-panel mosaic illustrating the History of Mathematics at UCLA. This pictures shows a small portion of that on the Math Science Building.
Young died in 2007. Much of his work was done back east, though he and his wife lived in LA and West Hollywood for decades. He lectured in Europe, and his murals adorn buildings in Chicago, Boston, and his hometown, Pittsburgh. Here's a tribute to Young from the Mosaic and Glass Art blog.
This picture--which really shows the work up close--is from the Los Angeles Murals Project website. I hope they don't mind me using it as more of a tease than a real representation of the work. To see more of the Mural Projects' pictures of Young's work, click here.
