THOMASCOLOR
35MM MULTICOLOR PROJECTION LENS
Thomascolor, Hollywood, California 1945-1947
Thomascolor
35mm multicolor projection lens, believed to have been manufactured by
Thomascolor, Hollywood, California, somewhere between 1945 and 1947.
One of at least eighty-six such color processes developed
between 1899 and 1977, Thomascolor
was an additive color motion picture film system, whereby a single image was
individually run through red, green, blue and violet filters before coming
together to create four distinct images within the space of one standard 35mm
frame of black-and-white film. After developing the film negative in the normal
manner, a positive print was made. The
four images clustered within each frame of the black-and-white positive were
then projected through the same color filter array to produce a single image on
the screen having the "color" film effect. Magazine articles through October, 1945 still
reference the use of four colors in describing the system, which by then was
being planned for use in the 16mm amateur format. The projection lens shown here, with only
three color filters (red, green, blue) and three lenses, is believed to be an
evolution of the original four-color arrangement.
Richard Thomas of Los Angeles, an optical engineer,
conceived the process and was granted at least eight patents relating to color
film systems:

The Thomascolor process was initially conceived for widescreen
film, Thomas having outfitted one Fearless 65mm Superfilm Camera with his lens
with enough components to complete six additional Fearless cameras. Thomas
conducted tests in 1942, apparently shelving the 65mm format. Theatrical and
film producer Michael Todd would end up acquiring these cameras some eight
years later, modifying them to create the first cameras used in the 70mm
Todd-AO widescreen format.
At various points, the company apparently operated under
the names of Richard Thomas Enterprises, Inc., Thomascolor Corporation,
Hollywood, California, and by September, 1947, Thomascolor, Inc. Patent
information indicates Richard Thomas was a resident of Los Angeles and Westwood
Village (a commercial district of Los Angeles) with two of his patents from
1941 and 1942 having been assigned to the Thomascolor Corporation, a
Corporation of Nevada. On January 25,
1951, the State of Delaware repealed the charter for the Thomascolor
Corporation, for failure to pay taxes during the prior two years.
I have yet to determine more about the Thomascolor company, how long it lasted and whether any motion pictures
ever materialized using this process in either 65mm or 35mm film. In 1948, the Securities and Exchange
Commission (SEC) investigated the practices of the company's certified public
accountant, taking issue with a 1947 audit that grossly overvalued the
company's patents and patent applications. The audit issues came about, just as
Thomascolor was registering to issue securities,
based on the strength of these financial statements.
A notation in Popular
Photography, November, 1947, stated that "Application for approval
of a 10-million-dollar common stock issue has been made by Thomascolor Corp.,
formed for the manufacture of equipment for making color pictures on
black-and-white film. The process, invented by Richard Thomas of Los Angeles,
was described in detail in the October, 1945 issue of Popular
Photography." Thomascolor
reportedly issued 200 shares before the SEC rescinded their approval.
