The Technicolor Notebooks at the George Eastman House

This survey of the Technicolor Corporation notebooks held by the George Eastman House is presented as an example of the value of scientific research and engineering records in the study of early colour and film preservation. An overview of the collection and examples of its holdings are given, and three of the notebooks are explored in detail. The development of the Technicolor process is discussed within the context of early additive and subtractive colour technologies, and of competing two and three colour systems. Examples are given of other artifacts in the collection, notably film frame clippings and a business correspondence index.
