Charles Dockum (1904-1977)


2017 NEWS: Three Charles Dockum Mobilcolor films have been released on CVM's DVD, Visual Music 1947-1986 from CVM Archive. Full title list and details here.



Charles Dockum was born in Texas in 1904, and earned a degree in electrical engineering at Texas A & M in 1926. His health required him to move to Arizona, where he began working on the production of projection machinery that could perform color abstract imagery moving in a harmony and counterpoint comparable to auditory music. He coined the term Mobilcolor for this new artform, and gave public performances in 1936 in Prescott, Arizona. He became well enough to move to California shortly thereafter, and he continued working on improved MobilColor projectors (he would make six models altogether) at his home in the Los Angeles suburb of Altadena. Dockum enjoyed successful performances at such places as the Pasadena Playhouse and the California Institute of Technology. In 1942, the Baroness Hilla Rebay awarded him a fellowship from the Guggenheim Foundation to build a new improved MobilColor projector that could be installed at the Guggenheim Museum. By 1950, Dockum had perfected the MobilColor IV, which could produce layered movements of diverse over-lapping imagery. Dockum built MobilColor V in the early 1960s, and continued to perform at various venues in California. The MobilColor VI remained unfinished at Dockum's death in 1977. (William Moritz)


From MOBILCOLOR, a Dockum Research Laboratory brochure: "About the Inventor"

Charles Dockum was born in Corsicana, Texas, in 1904. He obtained a degree in electrical engineering at Texas A & M in 1926. Immediately thereafter began his intense interest in art, particularly in composition employing the functional use of form and color as conceived in the contemporary movement in painting and architecture.

In 1935 he began the first experiments toward the development of Light Projection (MOBILCOLOR) as a fine art, combining a knowledge of music and the graphic arts with his previous training in electrical and illumination engineering. Several years later Color Concerts were given at Cal Tech and the Pasadena Playhouse.

Solomon R. Guggenheim recognized the importance of this work in 1942 and furnished generous funding for the following ten years. Mr. Guggenheim planned to establish an Institute of Light with the Dockum MOBILCOLOR Instrument at its center. His aims were, first, to present Color Concerts, and second, to furnish training for students and artists in composing with colored light.

Due to the death of Mr. Guggenheim and the loss of his funding, MOBILCOLOR was dormant until 1960, when the artist-inventor again started development of his own projection instrument in his studio at the Dockum Research Laboratory in Altadena, California. Beginning in 1971, Color Concerts were given at Cal State College, Hayward, and at Ramo Auditorium at Cal Tech, while continuous private showing were held at the studio. These included several series of Color Shows for surrounding colleges as well as single performances for many interested groups.

Currently, MOBILCOLOR VI is being designed to utilize a mini-computer as part of its composing and performing systems. Charles Dockum died in June, 1977, but his new concept of visual art and the development of color symphonies is continually going forward. (published by the Dockum Research Lab shortly after Dockum's death).


About Mobilcolor

Dockum, Charles:

The Dockum system of Mobilcolor Projection differs from previous efforts in this field in its practical means of generating mobile form elements, and in the sensitive and accurate control of these mobile forms of light toward the production of a logical and moving thematic development, analogous to the manner in which musical themes are composed into structural forms known as sonatas, fugues, symphonies, etc. Without such control no system can hope to meet the requirements of a great Art and hold a wide, sustained interest among composers, critics and the public. This system also provides a means of recording these visual compositions so that a permanent record remains of any composer's work, which can then be reproduced exactly as created.

Program Notes. These were given to visitors attending Mobilcolor Concerts, providing brief descriptions of the compositions. (Courtesy Dockum Research Laboratory).

GEOMETRICS: Sharply defined shapes develop rhythmically with emphasis on theme and variation. New colors are formed by the additive process of color mixing, unique to the medium of light.

SPARKLETTS: Forms are made up of scintillating points of light. The use of varying light intensities causes the forms to come forth or recede in space, thus assuming a primary or secondary role in the composition.

YARDS AND YARDS: A three-dimensional quality is produced by a special treatment of the objective lenses.

IMPROVISATIONS: Manual and mechanical manipulations demonstrate the versatility and artistic possibilities of MOBILCOLOR, and how an artist would compose in colored light.

Film Documentation An excerpt from Dockum's 1952 Mobilcolor Performance at the Guggenheim film, preserved by Center for Visual Music from the 16mm camera original (shot by Ted Nemeth), screened in the Visual Music exhibition at MOCA Los Angeles (February-May 2005) and The Hirshhorn Museum, Washington, D.C. (June to September, 2005). This film also screened at The Guggenheim Museum, New York, in 2005, accompanying their Hilla Rebay exhibition, in CVM's film series at The Guggenheim in 2010 accompanyiing the Kandinsky exhibition, at various other festivals internationally, and at The Hammer Museum, Los Angeles in 2009. This film and 2 others about Dockum's work travel in CVM's Essential Visual Music: Rare Classics film program, which has screened in the US and Australia. Other of Dockum's films have been screened by CVM at the International Film Festival Rotterdam, and LACMA, Los Angeles.

CVM is currently preserving Dockum's films. Several have been completed including a 1966 documentary by Dockum, and performance films from 1952, 1966, 1969 and 1970.

The 1969 Mobilcolor film screened at LACMA for six months, beginning August 2011, and was screened in Amsterdam at the Sonic Acts Festival, 2012. A note from the Amsterdam curator Joost Rekveld:

The Dockum film is GORGEOUS ! The audience was in a collective trance in especially the first, geometric section... The movements are very very very beautiful indeed. And even when I have a rough understanding of how his projector works, in this case I can't figure out how he could do this live. Amazing. The last and middle sections are great too. (Rekveld)


Selected Correspondence

Letter, Charles Dockum to Frank Lloyd Wright, June 10, 1944. Unpublished. Excerpt:

The Projector makes use of two groups of celluloid films, 4-1/4" wide, the three films of each group being superimposed before a projection aperture. By means of a seventh, control film, the films in each aperture group can be made to move either up or down, change speed or pause before the aperture. By this means designs carried on the films are made to modify each other as desired and produce rhythmic movements and effects over a wide range. The control film also governs the intensity of illumination. Special lens arrangements give the projections a luminous, prismatic quality.

The designs on the films are not drawn or painted on in the sense of painting a picture, as in animated cinematography. Rather the mathematical proportions are worked out which will give the desired results, and the films then opaqued to leave transparent "windows" which allow shafts or areas of light to pass through in guided movement.

--"Towards a Visual Music" in Cantrill's Filmnotes, 1985. Excerpt: "...the special intensities and subtleties of live light cause others, like Charles Dockum (1904-1977) to devote over 40 years to the perfection of his fine Mobilcolor Projector, a classic example of the plight of the color organ. The Mobilcolor, a large, complex mechanism, requires two people to operate it for an elaborate composition - but the resultant spectacle is definitely worth it. The imagery can be hard-edged or amorphous, and can be programmed to move at specific speeds in smooth, definite patterns. The wide range of controlled light intensity, with several (overlapping) sources, offers a visual delicacy that can not be reproduced on film or video."
