Edgar Collins and the new Cezanne

Edgar Collins, a wealthy art collector with a penchant for discovering unknown masterpieces, made headlines in 1992 with the unearthing of a previously undiscovered van Gogh. This painting had been held by a Japanese family for half a century before Collins brought it to light.

examinaton & results

Dr. Simpkins
no evidence of polyene were found

another compound quenching polyene to lower signal in back ground

part might be exposed to light

regions examined by both techniques might have aged differently

color of trees & roof top showed same technique found in Gardanne "Cezanne's painting"
examined fluorescence from image's surface using short & long UV wave excitation from mercury lamps
Dr. Montoya
this made the painting original from an x-ray spectroscopist's point of view
the excitation then de-excitation of the inner electrons showed that the composition of painting is as that of pigments used during Cazenne's life
examined the composition elements of blue, yellow & green taken from different colored areas by x-ray fluorescence
Dr. Anderson & Dr.Philip Marden
all this indicates that the painting may not be Cezaenne
the binder used is an animal glue binder
IR refractography indicated an underdrawing by charcoal
another technique will be used to detect metal nuclie in its composition elements
yellow areas indicated the possibility of cadmium yellow lithosone, mix that was used 20 years after Cazenne's death
used infrared (IR) spectroscopy to detect anomlies beneath the paint
Dr. Pruschy
to control for possible contamination other samples were taken & they all gave the same results
this suggests the painting to be approximatly 100 years old
this showed the absorption of polyene that oxidizes over time reaching 0.6
examined a paint chip by using ultraviolet (UV) spectum of incident light
Dr. Marden
painting is not signed but that isn't unusual & its about 55 by 125 centimeters
similar to Cezanne at the Barnes foundation in Merion with many similar visual elements but different arrangement and composition
declares the painting orginalty by using low magnification under microscope which showed that the structure of brushwork is the same as of other paintings
dated the painting to the late 1880's

he donated a new Paul Cezanne to the city's metropolitan museum

an investigation carried by spectrotech and university professors to examine the painting
it was known that there aren't any undiscovered Cazenne

personal information

he decided to donate art work to public musems all over the world
wealthy collector of fine art & interested in finding undiscovered work
in 1992 he discovered a new van Gogh that belonged to a japanese family for 50 years
amasses billions from Indochiniese & Chinese telecom venture
dropped out of graduate school in 1988
