Daniel J. Shanefield
From Wikipedia, the free encyclopedia
Daniel Jay Shanefield (born 1930 in Orange, New Jersey, USA) is a ceramic engineer. He married Elizabeth Stewart Davis in 1964 and has two children, Alison and Douglas.
Shanefield studied at Yale, Columbia, and Rutgers and received his PhD in Physical chemistry from Rutgers University in 1962. After working for 5 years at ITT Corp., he went on to work at Bell Laboratories in Princeton, New Jersey. In 1986 he then taught ceramic engineering at Rutgers University in Piscataway, New Jersey and is now professor emeritus there.
At Bell Laboratories, Shanefield developed new products and transferred the technologies to manufacturing facilities within AT&T Corp. He is well known for his work on ceramic components for electronics, such as insulators fabricated by the "tape casting" process. Over 200 million of these insulators have been made, and there is one installed in almost every telephone line in the United States. (Tape casting, along with technologies developed by other people, is used to make multilayer ceramic capacitors. More than one billion of those are made every day, and they are in almost all electronic equipment.)
Shanefield is the recipient of four AT&T Outstanding Achievement Awards. He received the Best Paper Award of the American Ceramic Society in 1993 and the Man Of The Year Award of the Ceramic Association of New Jersey in 1996. Shanefield is a Fellow of the American Institute of Chemists and of the American Ceramic Society, and he is a Life Member of the IEEE.
As a part-time writer for both popular magazines and professional journals in electronics engineering, Shanefield is notable for first describing double-blind listening comparison of audio components in the November, 1974 newsletter of the Boston Audio Society. This test is now used worldwide for determining whether measurable improvements in music reproduction equipment are actually audible.
Dr. Shanefield is the author of two college textbooks, "Organic Additives And Ceramic Processing" (Kluwer Acad. Publ., 1996) and "Industrial Electronics For Engineers, Chemists And Technicians" (William Andrew Publ., 2001).
