Kenneth Swezey was born in Brooklyn on 11 June 1904. His mother, Carrie, was 42 at the time and his father, Edwin L. Swezey, was 47. He had a sister, Martha, who was 13 years older and a sister, Anna, who was 25 years older. From early on he wrote about science and technology, selling his first article, on how to make a
wet cell battery, at age 11. In his late teens he got a job writing a column on
radio technology for the New York paper
The Sun. He would go on to contribute articles as a freelance writer for various magazines such as
The Experimenter, ''
Boys' Life, and Popular Science (a reappearing series of "Home Experiments''" articles). He would often illustrated his articles with photographs he shot himself. He lived with his parents up into his twenty's but by his thirty's he was living alone in a nearby residence on Milton Street in Brooklyn, New York. After World War II he wrote many books explaining scientific principles, sometimes equating them with everyday life and use in the home workshop. He died of a heart attack in 1972 at the age of 67. ==Association with Nikola Tesla==
