John Nash Ott (23 October 1909 – 6 April 2000[1]) was a photo-researcher, writer, photographer, and cinematographer who was an early adopter of many modern photographic practices, including time-lapse photography andfull-spectrum lighting.[citation needed]
Ott's early career was in finance. He never went to college,[2] although he enrolled in finance courses at Harvard Business School while working for several Chicago area banks. During this period, he developed an interest intime-lapse photography. He made his first time-lapse film in 1927, while he was still in high school,[3] but did not develop the automated mechanical camera rig he used in his later films until 1937. His early amateur films led him to a career incinematography. In addition to making films, he performed research about the effects of natural lighting on plants, animals, and humans.
Initially, Ott's interest in time-lapse movie photography, mostly of plants, was just ahobby. Starting in the 1930s, Ott bought and built more and more time-lapse equipment, eventually building a largegreenhouse full of plants, cameras, and self-built automated electric moving camera systems (the first movie cameramotion control systems ever built) for moving the cameras to follow the growth of plants as they developed. He time-lapsed his entiregreenhouse of plants and cameras as they all worked and grew.
His work caught the attention of organizations who employed him to make time-lapse segments for films they were producing, including the educational filmSecrets of Life, for theWalt Disney Company in 1956,[3] andThe Story of Wheat, for theSanta Fe Railroad.[3] From the late 1940s to the early 1950s he hosted a Chicago-area television program calledHow Does Your Garden Grow, which featured gardening tips, botanical information, and short time-lapse films. Episodes of this program can be viewed on the YouTube page of theWinnetka Historical Society.[4] More episodes ofHow Does Your Garden Grow, Ott's educational films, and raw time-lapse footage can be viewed from theChicago Film Archives' John Nash Ott Collection.[5]
In the later years of his life, Ott developed a theory that movement of plants could be manipulated by varying the amount of water that plants were given, and varying thecolor temperature of the lights in the studio, with some colors causing the plants to flower and other colors causing the plants to bear fruit. His 1958 memoirMy Ivory Cellar details not only his personal history as a filmmaker, but also outlines these ideas.
Ott's experiments with different colored lighting systems and their effects on thehealth of plants led toexperiments with colored lights on the health of animals, humans, and individual cells, using time-lapse micro-photography. Ott's experiments led him to believe that only afull spectrum of natural light (including natural amounts ofinfrared andultraviolet) could promote full health in plants, animals, and humans. He wrote the 1973 bookHealth and Light advancing his theories. Such topics were also addressed in his 1974 filmExploring the Spectrum.
Ott received an honorary doctorate in science fromLoyola University of Chicago in 1958.[6] Although it is not customary for recipients of such an honorary doctorate to adopt the prefix "Dr.", he was widely referred to as "Dr. Ott" thereafter.[by whom?]
Ott believed that the proprietarylighting technology he developed was the closest replication of the Sun's natural wavelengths. He developed several consumer products based on this technology, including altered lightbulbs and a special pair of polarized sunglasses which he believed would enhance the physical and mental fortitude of anyone wearing them.[7]
