Paul J.Sachs was director of the Harvard Fogg Art Museum and one of the precursors of modern museology. In 1922, an innovative course on the work at the Museum and its problems began to be taught at Harvard University. In addition to themes directly related to art, the course also dealt with themes related to the management and financing of museums. From the schools of Sachs many students passed by who would later be the directors and managers of the major museums of the United States and Europe, so their vision had a great influence on the museum of the 20th century.

Sachs also worked in organizing exhibition spaces. He believed the work was too high and in the Fogg the painting decided to go down to the eye of the spectator. The truth is that Sachs was a small man, who didn't reach the subway and a half. His disciples took that height as a standard and for years hung the works in many museums around the world underneath it.
