'''Daniel Jay Shanefield''' (April 29, 1930 – November 13, 2013<ref>[http://obits.staradvertiser.com/2013/11/23/daniel-j-shanefield/ Daniel J. Shanefield « Honolulu Hawaii Obituaries - Hawaii Newspaper Obituaries<!-- Bot generated title -->]</ref>) was a [[United States]] [[Ceramic engineering|ceramic engineer]].

Shanefield was born in [[Orange, New Jersey]], and earned a bachelor's degree in chemistry from [[Rutgers University]] in 1956; he went on to graduate studies at the same university, receiving his Ph.D. in [[physical chemistry]] from Rutgers in 1962. He worked from 1962 to 1967 at [[ITT Corporation|ITT Research Laboratories]], and from 1967 to 1986 at [[Bell Laboratories]]. In 1986 he returned to Rutgers as a Professor II (a professorial rank at Rutgers that is one step above a normal full professor).<ref name="abet">Biographical sketch from [http://www.rci.rutgers.edu/~cannon/ABET%20ss.pdf documents for 2000 ABET Engineering Program review], Rutgers University, retrieved 2011-04-03.</ref>

At Bell Laboratories, Shanefield was the co-inventor with Richard E. Mistler of the [[tape casting]] technique for forming thin ceramic films.<ref>{{citation|title=Surfactants in emerging technologies|volume=26|series=Surfactant science series|first=Milton J.|last=Rosen|publisher=CRC Press|year=1987|isbn=978-0-8247-7801-9|url=https://books.google.com/books?id=5mbHGj8XriIC&q=shanefield|page=89}}.</ref> He pioneered the development of a [[phase-change memory]] system based on an earlier patent of [[Stanford R. Ovshinsky]]; Shanefield's work in this area "represented the first proof of the phase change memory concept".<ref>{{citation|title=Phase Change Materials: Science and Applications|first1=Simone|last1=Raoux|first2=Matthias|last2=Wuttig|publisher=Springer-Verlag|year=2008|isbn=978-0-387-84873-0|url=https://books.google.com/books?id=AO3SNSM2ykUC&dq=shanefield&pg=PA7|pages=7–9}}.</ref> Beginning in the mid-1970s, Shanefield was an early proponent of [[double-blind test|double-blind]] [[ABX test]]ing of [[high-end audio]] electronics; in 1980 he reported in [[High Fidelity (magazine)|''High Fidelity'' magazine]] that there were no audible differences between several different [[power amplifier]]s, setting off what became known in [[audiophile]] circles as "the great debate".<ref>{{citation|last=Nousaine|first=Tom|contribution=The Great Debate: Is Anyone Winning?|title=8th International Conference: The Sound of Audio|publisher=Audio Engineering Society|year=1990|url=http://www.aes.org/e-lib/browse.cfm?elib=5426}}.</ref>

Shanefield is the author of two books, ''Organic Additives and Ceramic Processing'' (Kluwer, 1995; 2nd ed., Kluwer, 1996) and ''Industrial Electronics for Engineers, Chemists, and Technicians'' (William Andrew Publishing, 2001).<ref>[http://mse.rutgers.edu/about/history_mse Books Written by Faculty] {{webarchive|url=https://web.archive.org/web/20110415091158/http://mse.rutgers.edu/about/history_mse |date=2011-04-15 }}, Rutgers Materials Science and Engineering, retrieved 2011-04-01.</ref>

He was a four-time winner of the AT&T Outstanding Achievement Award<ref name="abet"/> and was elected as a Fellow of the [[American Ceramic Society]] in 1993.<ref>[http://ceramics.org/wp-content/uploads/2009/06/fellows_recipients_2009.pdf American Ceramic Society Fellows as of 2009] {{webarchive|url=https://web.archive.org/web/20110725012424/http://ceramics.org/wp-content/uploads/2009/06/fellows_recipients_2009.pdf |date=2011-07-25 }}, retrieved 2011-04-01.</ref>

Shanefield died in Honolulu, Hawaii, aged 83.
