Early life and education

Jack St. Clair Kilby was born on November 8, 1923, in Jefferson City, Missouri. He was raised in Great Bend, Kansas, where his father ran a small electric company that served customers in rural western Kansas. While in high school, a huge ice storm knocked down most of the poles that carried the telephone and electric power lines. His father's company had to use amateur radio operators for communication in the areas where customers had lost their power and phone service. This event sparked his interest in electronics.

After serving in the U.S. Army as an electronics technician during World War II, Kilby began studying electrical engineering at the University of Illinois, graduating with a B.S. in 1947. He then joined the Centralab Division of Globe Union, Inc., an electronics manufacturer in Milwaukee, Wisconsin. While working in Milwaukee, Kilby continued his education at the Milwaukee State Teachers College (now the University of Wisconsin–Milwaukee), where he obtained an M.S. in 1950.
