February 6, 1959 – Kilby Files Patent for Integrated Circuit
On February 6, 1959, Jack St. Clair Kilby filed his patent application for the integrated circuit, less than six months after the idea came to him. Kilby first demonstrated a multivibrator circuit of discrete silicon elements in late August 1958 to his then-new employer Texas Instruments. As a new employee, he was not yet entitled to the mass summer vacation that was customary among TI employees at the time. During this relatively quiet time around TI, Kilby first came up with the idea of the IC. In September 1958, Kilby demonstrated the first IC to TI management. The company was supportive, but the reaction from potential users, specifically military organizations, was mixed. After much debate, a small group within the Air Force picked up on the IC.
