Who was Jack Kilby?

Jack Kilby, an engineer and recipient of the Nobel Prize for physics (along with Robert Noyce) is largely responsible for creating the modern integrated circuit (also called a microchip), as well as several other inventions throughout his life.

Early Life:

While there is some debate as to whether Jack was born in either Missouri or Kansas, he certainly spent the majority of his childhood in Great Bend, Kansas. Born into an educated family, both of Jack’s parents Hubert and Vina Kilby held Bachelor of Science degrees from the University of Illinois. Hubert’s work as the manager of a local utility company sparked Jack’s love for electronics. During Jack’s teenage years an ice storm disrupted electric service to much of the Midwest, including his father’s customers. Huber Kilby was determined to do whatever it took to run the utility company and help his customers through the duration of the storm, so he communicated with his employees and customers via amateur radio. Jack Kilby even went so far as to get his FCC license and build his own radio.

After completing his high school education Jack joined his family’s alma mater, attending the University of Illinois and studying electrical engineering. Shortly into his tenure at university Jack enlisted in the United States Army Signal Corps and began helping small units of soldiers communicate with the big Army using the backpack radio he was issued prior to deployment. His fascination and earlier experience building his own amateur radio during high school gave him the idea to improve upon those standard-issue radios using other radio parts he had access to at the time, making his radio better suited to deployment conditions. 

Career:

After the war Jack finished his Bachelor’s degree and went on to further his education with a Master’s degree from the University of Wisconsin in 1950. 

Globe Union Inc.

His first job had him working for Globe Union Inc. designing and developing parts for radios, televisions, and other audio equipment. Specifically, Jack worked with semiconductors and circuits. In 1952 Globe Union Inc. sent him to work with Bell Laboratories to learn more about their new transistors, and Jack was enamored by the possibility of a technology capable of replacing the clunky, fragile vacuum tubes used up to that point. Jack Kilby noticed an issue with the new transistors Bell Laboratories had developed; there were still too many electrical connections within too confined of a space to live up to the engineer’s designs. Jack Kilby wanted to work toward a solution to this issue, but could not do so with Globe Union Inc.

Texas Instruments

Jack was now working with Texas Instruments, who agreed to let him pursue a solution to the miniaturization of electronic components (later called microchips), and ultimately the development of the first integrated circuit (see more about integrated circuits here). Shortly after starting with Texas Instruments Jack Kilby was able to develop a proof of concept for the first integrated circuit. This proof of concept got Kilby to lead teams that developed several inventions, including the first military systems and computers incorporating integrated circuits. His work also resulted in the first handheld calculator, called the “Pocketronic”, which used these new microchips to complete complex calculations. The new invention also allowed for the invention of the first thermal printer. In 1959 Jack Kilby filed his patent for the first integrated circuit with the U.S. Patent 3,138,743, which was officially referred to as “miniaturized electronic circuits” (later known as microchips). Jack Kilby shares the credit for creating the first integrated circuit with Robert Noyce, who created a similar integrated circuit on his own just months after Kilby, and later went on to co-found Fairchild Semiconductor and Intel Corporation. 

For roughly a decade Jack Kilby continued to develop circuits and lead projects for computers, military systems, and industrial equipment. In 1970 Jack took a hiatus from Texas Instruments to work on his own projects, including exploring an early concept for solar panels by using sunlight to generate electrical power. 

Texas A&M

From 1978 to 1984 Kilby returned to the world of education while working as a professor of electrical engineering at Texas A&M University. It was during this time Jack officially retired from Texas Instruments, although he did remain involved in the company’s projects a few more years. 

What is Jack Kilby Known for?

Integrated Circuit

Jack Kilby is the man responsible for the invention of the integrated circuit (also known as the microchip). However, Jack does not take singular credit for this invention as Robert Noyce also created a similar device independently of Kilby just months later. 

Jack Kilby: Marriage, Divorce, Children, and Personal Life

Net Worth 

While Jack Kilby had an illustrious career manufacturing some of technology’s most important inventions and winning several awards, it is unclear just how much his achievements added to his net worth. 

Marriage

Although it’s unclear when the two got married and started their family, Jack Kilby married Barbara Annegers Kilby.

Children

Together, Jack and Barbara had two daughters: Ann Kilby and Janet Kilby. It was in 1958 that Jack and Barbara Kilby moved to Dallas, Texas, so Jack could begin what would become some of his most important work with the prominent Texas Instruments. 

Jack Kilby: Awards and Achievements

It was in December of 2000 that Jack Kilby officially received the Nobel Prize in Physics, which he stated was a complete surprise. Although Robert Noyce was long dead at the time of receiving the Nobel Prize, Kilby did mention he would have shared it if Noyce was still alive. In the Summer of 2005 the then 81-year-old Jack Kilby was taken by cancer. Throughout his lifetime Jack had been awarded at least nine patents, having filed several more. In addition to his Nobel Prize in Physics, Kilby also received several awards and honors from the Institute of Electrical and Electronics Engineers (IEEE), as well as the awards from various foundations and institutes, such as the National Medal of Science and the National Medal of Technology. Kilby was even inducted into the National Inventors Hall of Fame in 1982. A full list of Kilby’s awards can be seen below:
