Jack St.Clair.

Jerry Merryman.

James von Tassel
There are few living men whose insights and professional accomplishments have changed the world. Jack Kilby is one of these men. His invention of the monolithic integrated circuit - the microchip - some 30 years ago at Texas  Instruments (TI) laid the conceptual and technical foundation for the entire field of modern microelectronics. It was this breakthrough that made possible the sophisticated high-speed computers and large-capacity semiconductor memories of today's information age. 

Jerry D. Merryman

Jerry D. Merryman joined TI in 1963 and remained with the company for 30 years. He was one of three team members responsible for the invention of the handheld electronic calculator, and served as project manager and logic designer for the two-year project.
