Daniel Jay Shanefield (April 29, 1930 – November 13, 2013〔(Daniel J. Shanefield « Honolulu Hawaii Obituaries - Hawaii Newspaper Obituaries )〕) was a United States 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 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).〔Biographical sketch from (documents for 2000 ABET Engineering Program review ), Rutgers University, retrieved 2011-04-03.〕 At Bell Laboratories, Shanefield was the co-inventor with Richard E. Mistler of the tape casting technique for forming thin ceramic films.〔.〕 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".〔.〕 Beginning in the mid-1970s, Shanefield was an early proponent of double-blind ABX testing of high-end audio electronics; in 1980 he reported in ''High Fidelity'' magazine that there were no audible differences between several different power amplifiers, setting off what became known in audiophile circles as "the great debate".〔.〕 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).〔(Books Written by Faculty ), Rutgers Materials Science and Engineering, retrieved 2011-04-01.〕 He was a four-time winner of the AT&T Outstanding Achievement Award〔 and was elected as a Fellow of the American Ceramic Society in 1993.〔(American Ceramic Society Fellows as of 2009 ), retrieved 2011-04-01.〕 Shanefield died in Honolulu, Hawaii, aged 83. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Daniel J.
