While working with the Dayton-Wright Company he developed the "Bug" aerial torpedo, considered the world's first aerial missile.

==Early life==
Charles was born in Loudonville, Ohio, USA, the fourth of five children of Jacob Kettering and Martha Hunter Kettering. Poor eyesight gave him headaches in school. After graduation he followed his sister Emma into a teaching position at Bunker Hill School. By all accounts he was an engaging and innovative teacher. He attracted students to evening scientific demonstrations on electricity, heat, magnetism, and gravity.
He took classes at The College of Wooster, before transferring to The Ohio State University. He was a member of the Delta Upsilon Fraternity. Eye problems forced him to withdraw, and he took a job as foreman of a telephone line crew. At first, the termination of his studies caused him to be depressed. Then he found ways to apply his electrical engineering skills on the job, and his spirits revived. He also met his future wife, Olive Williams. When his eye condition improved, he was able to return to his studies and graduated from OSU in 1904 with an electrical engineering degree.
