Justin Gordon Holt (19 April 1930 – 20 July 2009) was an audio engineer and the founder of Stereophile magazine, and is widely considered to be the founder of the high-end audio movement, which promoted the philosophy of judging sound quality by subjective tests, generally with "cost no object" sound components, including loudspeakers, turntables, amplifiers, vacuum tube components, cables, and other devices. Known as "JGH" (from his byline in published reviews and articles), Holt established a reputation for veracity, often-controversial opinions, passionate critiques, and journalistic integrity. He also pioneered the concept of the yearly "Recommended Components" list, providing a thumbnail summary of reviews for audiophiles looking for the finest sound components available at any price. Holt also came up with "Holt's Law," the theory that the better the recording, the worse the musical performance—and vice versa.
Justin Gordon Holt was born on April 19, 1930, in Charlotte, North Carolina, and adopted when he was two years of age by Justin Gordon Holt (Sr.) and his wife Katherine (née Hart). Through DNA testing and genealogy research, Holt's son was able to confirm that Gordon was from the Beam and Houser families of North Carolina. His family moved to Melbourne, Australia in 1937 for his father's work, and stayed there through World War II. From 1936 to 1946 Gordon attended the prestigious Melbourne private school Scotch College, returning to the U.S. after his father's sudden death from a stroke on 9 August 1946. J. Gordon Holt's father bore such a striking resemblance to famed gangster Al Capone that he was stopped and questioned by a customs official. During his years in Australia his mother worked as the head of the USO for the Australian Red Cross, and his father worked for a textile company.
Gordon attended Nether Providence High School in Wallingford, Pennsylvania, and attended Lehigh University with the intent of becoming an engineer. After discovering he "couldn't hack the math," Gordon switched his major to Journalism. He graduated in 1953 with a BA. He spent a few years struggling as a cartoonist, and writing the occasional article for High Fidelity magazine, which later offered him a position.
