Tarzana is a 70.7% white, affluent, highly educated neighborhood in the San Fernando Valley region of the city of Los Angeles, California. Tarzana is a mostly residential community on the site of a former ranch owned by author Edgar Rice Burroughs. It is named after Burroughs' storybook jungle character hero, Tarzan of the Apes.
Professor Tesla Kidder lived and worked in Tarzana. Since he was a mad scientist, he had his own private laboratory in the town. While he tried to be a good neighbor, some of his experiments did cause problems. One, a "stop light", caused an area with a radius of 1.378 miles to plunge into absolute darkness. Fortunately the AAA battery that powered his device failed after a couple of hours, restoring the light.
