Leo A. Marzolo

Leo Aurelio Marzolo (February 22, 1887 – March 1964) was a restorer of paintings at the Art Institute of Chicago[1] and was also a painter.

He studied at the Chicago Gallery Association and the Palette and Chisel Academy.

Marzolo may have restored the "Madonna of Bogotá" painted by Raphael Sanzio of Urbino circa 1517.

However, there are doubts as to whom restored the said Madonna of if a copy was made.

The two possible candidates for either one of them were Leo A. Marzolo and Sheldom Keck.
