John R. Pierce

John Robinson Pierce (March 27, 1910 – April 2, 2002), was an American engineer and author. He worked extensively in the fields of radio communication, microwave technology, computer music, psychoacoustics, and science fiction. Born in Des Moines, Iowa, he earned his PhD from Caltech, and died in Palo Alto, California from complications of Parkinson's Disease.

At Bell Labs

Pierce wrote on electronics and information theory, and developed jointly the concept of Pulse code modulation (PCM) with his Bell Labs colleagues Barney Oliver and Claude Shannon. He supervised the Bell Labs team which built the first transistor, and at the request of one of them, Walter Brattain, coined the term transistor; he recalled:

Pierce's early work at Bell Labs was on vacuum tubes of all sorts. During World War II he discovered the work of Rudolf Kompfner in a British radar lab, where he had invented the traveling-wave tube; Pierce worked out the math for this broadband amplifier device, and wrote a book about it, after hiring Kompfner for Bell Labs. He later recounted that "Rudy Kompfner invented the traveling-wave tube, but I discovered it." According to Kompfner's book, the statement "Rudi invented the traveling-wave tube, and John discovered it" was due to Dr. Eugene G. Fubini, quoted in The New Yorker "Profile" on Pierce, September 21, 1963.

John R.

John R. (born John Richbourg, August 20, 1910, Manning, South Carolina; died February 15, 1986, Nashville, Tennessee) was an American radio disc jockey who attained fame in the 1950s and 1960s for playing rhythm and blues music on Nashville radio station WLAC. He was also a notable record producer and artist manager.

Richbourg was arguably the most popular and charismatic of the four announcers at WLAC who showcased popular African-American music in nightly programs from the late 1940s to the early 1970s. (The other three were Gene Nobles, Herman Grizzard, and Bill "Hoss" Allen.) Later rock music disc jockeys such as Alan Freed, Wolfman Jack, and others mimicked Richbourg's practice of using speech that simulated African-American street language of the mid-twentieth century.

Richbourg's highly stylized approach to on-air presentation of both music and advertising earned him popularity, but it also created identity confusion. Because Richbourg and fellow disc jockey Allen used African-American speech patterns, many listeners thought that both announcers were actually African-Americans. The disc jockeys used the mystique to their commercial and personal advantages until the mid-1960s, when their racial identities as Euro-Americans became public knowledge.
