In 1923, Dr. Mees was elected a director of the Eastman Kodak Company, and in 1934 Vice President in charge of Research and Development.

In 1934, Dr. Mees established a branch of the Laboratory to carry on research on cellulose acetate yarn and plastics for the Tennessee Eastman Corporation.

Dr. Mees has published over one hundred important scientific papers and a number of books. The greatest of these is his last book, "The Theory of the Photographic Process", published in 1942. It was written to form a compendium of knowledge of the subject to which Dr. Mees decided to devote his life - the subject indicated by the title. By bringing together the results of the research of all who have contributed worthwhile knowledge to it, it must play a prominent part for photographic research by providing a stimulus for the research workers of the future.

In the sixty-one years of Dr. Mees' full and fruitful life, he has naturally been the recipient of a large number of honors and medals. Of these, he is perhaps most proud of the Draper Medal of the National Academy of Sciences, and the Fellowship of the Royal Society of London, the world's oldest and most coveted scientific distinction.

Among his many photographic distinctions, Dr. Mees is an Honorary Fellow of the Photographic Society of America, an Honorary Fellow of the Royal Photographic Society, an Honorary Member of the Societe Francaise de Photographic, an Honorary Master of Photography of the Photographer's Association of America, and an Honorary Member of the Association for Scientific Photography.

Those who work with Dr. Mees see no sign of relaxation in his vigor, vision, and resourcefulness. He believes that he has been successful in the sense that he has seen the two ambitions of his life realized: the establishment of the science of photography, and the recognition of industrial research as one of the great departments of all business and the main hope for improvements in the economic system of the future.
