== Biography ==
Born in 1945 and raised in Hart, Michigan, Kelly was influenced by his father, Lawrence, who worked on repairing auto bodies. His father had a set of Popular Science magazines which he read through often with much interest as a boy. As a 12-year old boy Kelley did an experiment one day based on one of these magazine articles. He understood that ruby was a chemical mixture of aluminum oxide and chromium oxide. He observed that some sandpaper that his father used had aluminum oxide dust. Kelley took some of this dust and placed onto a firebrick. He put a chip of chrome with the aluminum oxide sandpaper dust, melted them with high heat, and serendipitously created his first ruby, albeit of poor quality.〔 〕
As a teen, Kelley fostered his interest in science and experimentation. As a thirteen year old he shot homemade rockets over the local lake. He got into trouble with local police authorities when permission was denied to shoot these rockets so close to a heavily populated area.〔 〕
Kelley and his brother Arthur made some small wooden workshops in 1961 to do experiments with chemicals. In 1962 when they blew up these workshops after mixing sulfur potassium chlorate with aluminum oxide dust the boys were seriously injured but survived.〔 〕
