Dr. Clarence Lester "Les" Hogan (born 19xx) is a pioneer in microwave and semiconductor technology. — He grew up as brother of three sisters in Great Falls, Montana, where his father worked for the Great Northern Railroad. After graduating from Montana State University with a degree in chemical engineering he joined the U.S. Navy in 1942. He did some work on acoustic torpedoes in Chesapeake Bay, and when being approached by Bell Laboratories, subsequently went to the Pacific theatre to train submarine crews in the use of that technology.

After the war he did post-graduate studies at Lehigh University and obtained a Ph.D. in Physics. He then joined Bell Labs in 1950. A couple of months later he invented the Microwave Gyrator (a device which can simulate inductance by substituting an RC circuit, thus getting rid of awkward coil assemblies). He worked under Bill Shockley, inventor of the transistor and Nobel Prize laureate. From 1953 through 1958 he was a professor at Harvard University, when he was asked by Dan Noble to join Motorola in Phoenix, Arizona as general manager of the semiconductor operation.

In 1968 he changed to Fairchild Camera & Instrument as manager of integrated circuit and microprocessor development, taking eight senior executives (nicknamed Hogan's Heroes) with him. This move caused Motorola to sue Fairchild (unsuccessfully) for theft of trade secrets. He later became president of Fairchild and vice-president/ general manager of Fairchild Semiconductors, Palo Alto, California.

In 1975 he received IEEE's "Frederik Philips Award". In 1978 he was honoured with the "AeA Medal of Achievement". In 1993 he received the "MTT-S Microwave Pioneer Award". In 1996, a chair at the department of Electrical Engineering and Computer Science at the University of California, Berkeley was named in his honor. On October 20, 1999, he was inducted as "Eminent Member" of Eta Kappa Nu, "the society’s highest membership classification, to be conferred upon those select few whose technical attainments and contributions to society through leadership in the field of electrical and computer engineering have resulted in significant benefits to humankind".

He was among the people who signed the "Anti Global Warming Petition", which advocates that "Predictions of global warming are based on computer climate modeling, a branch of science still in its infancy. The empirical evidence [from] actual measurements of Earth's temperature shows no man-made warming trend" and is opposing the 1997 Kyoto Protocol.
