Charles M. Falco

Charles M. Falco (born August 17, 1948) is an American experimental physicist and an expert on the magnetic and optical properties of thin film materials.

In addition to his scientific research, in 1975 Falco was one of three participants in Chris Burden's performance art piece '220', and since 1985 his photography has been represented by the agency PhotoResearchers.

[4] For this work he received an award from the International Association of Art Critics, along with architect Frank Gehry, museum director Thomas Krens, and filmmaker Ultan Guilfoyle.

In 2000, Falco began collaborating with the British-American artist David Hockney, resulting in their discovery of scientific evidence in paintings made as early as c.1430 that demonstrated portions of them were created with the aid of optical projections.

Hockney's 2001 book Secret Knowledge resulted in widespread coverage of the "Hockney-Falco Thesis" in the popular media, including an hour-long BBC special and a segment on the CBS show 60 Minutes.
