Gordon Kidd Teal (January 10, 1907 – January 7, 2003) was an American engineer. He invented a method of applying the Czochralski method to produce extremely pure germanium single crystals used in making greatly improved transistors. He, together with Morgan Sparks invented a modification of the process that produced the configuration necessary for the fabrication of bipolar junction transistors. He is most remembered for developing the first silicon transistor while at Texas Instruments.

Early years[edit]

Teal was born in South Dallas, Texas to Olin Allison Teal and Azelia Kidd.[1] His father had come to Texas in 1897 from Georgia. Gordon was valedictorian at the Bryan Street High School in Dallas, Texas.[1] Gordon earned his undergraduate degree from Baylor University and a doctorate in Physical Chemistry from Brown University in 1931. While at Brown, he began work in the laboratory of Professor Charles Kraus on the then useless element, germanium. He joined Bell Labs in 1930.

The invention[edit]

When William Shockley's group at Bell Labs invented the transistor in 1947 Teal realized that substantial improvements in the device would result if it was fabricated using a single crystal, rather than the polycrystalline material then being used. He started a "boot-leg" project with very few resources or managerial support to make a simple crystal.

Texas Instruments[edit]

In 1952 Dallas-based Texas Instruments had purchased a license to produce germanium transistors from Western Electric, the manufacturing arm of AT&T and placed an ad in the New York Times for a director of research. Teal, becoming homesick for his native Dallas, responded and was hired by Patrick E. Haggerty. Teal started at TI on 1 January 1953, bringing with him all his expertise in growing semiconductor crystals. Haggerty had hired him to establish a team of scientists and engineers to keep TI at the leading edge of the new and rapidly expanding semiconductor industry. Teal's first assignment was to organize what became TI's Central Research Laboratories (CRL). Because of Teal's background, this new department was modeled after Bell Labs.

First silicon transistor[edit]

In April 1954 Teal's TI CRL team created the first commercial silicon transistor and tested it on 14 April 1954. On 10 May 1954 at the Institute of Radio Engineers (IRE) National Conference on Airborne Electronics, in Dayton, Ohio, Teal revealed this achievement to the world when he announced, "Contrary to what my colleagues have told you about the bleak prospects for silicon transistors. I happen to have a few of them here in my pocket." Teal also presented a paper, "Some Recent Developments in Silicon and Germanium Materials and Devices," at this conference.[2]

Other major achievements[edit]

Teal was hired to create and staff TI's CRL and was particularly proud of the outstanding talent recruited and developed as well as their subsequent impact on TI. In 1957 CRL developed a chemical reduction process for ultra-pure silicon. In 1958 a CRL employee, Jack Kilby, created the first integrated circuit. Other break-through developments include many advancements in infrared technology, and digital signal processing initially developed for the oil exploration industry, then for space and defense applications.

During 1963 and 1964 Teal became the International Technical Director for TI, promoting TI's growth as an international company. He resided in England, France, and Italy and was most active in their scientific and industrial aspects.

First Director of the Institute for Materials Research[edit]

In 1965, Teal, taking a leave of absence from Texas Instruments, became the first Director of the National Bureau of Standards' Institute for Materials Research in Washington, D.C.

Death and legacy[edit]

He died on January 7, 2003.[1]

In May 2013, the Board of Regents of Baylor University honored Teal by naming a new residence hall the Gordon Teal Residential College.
