John R. Dunning

John Ray Dunning (September 24, 1907 – August 25, 1975) was an American physicist who played key roles in the Manhattan Project that developed the first atomic bombs. He specialized in neutron physics, and did pioneering work in gaseous diffusion for isotope separation. He was Dean of the School of Engineering and Applied Science at Columbia University from 1950 to 1969.

Early life

John Ray Dunning was born in Shelby, Nebraska, on September 24, 1907, the son of Albert Chester Dunning, a grain dealer, and his wife Josephine Dunning née Thelen. He graduated from Shelby High School in 1925,and entered Nebraska Wesleyan University where he became a member of Phi Kappa Tau fraternity, and received a Bachelor of Arts (B.A.) degree in 1929.

After graduation, Dunning commenced a doctoral program at Columbia University. In 1932, James Chadwick discovered the neutron, which influenced Dunning's career, as he thereafter devoted much of his professional interest to the characteristics and uses of this particle. Dunning's research was enthusiastically supported at Columbia by George B. Pegram. In 1933, Dunning was an instructor at Columbia University from 1929 to 1932, and a university fellow from 1932 to 1933. He received his Ph.D. in 1934, writing his thesis on "The Emission and Scattering of Neutrons" under Pegram's supervision.

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.

Dunning

Dunning is a small village in Perth and Kinross in Scotland with a population of about 1,000. The village is built around the 12th-13th century former parish church of St. Serf, where the Dupplin Cross is displayed (Historic Scotland; open in summer without entrance charge). The building was used in the filming of the Scottish film Complicity. It is in Strathearn, the valley of the River Earn, north of the Ochil Hills. It is just south of the A9, between Auchterarder and Perth.

Dunning is steeped in history from the earliest days. There was an Iron Age fort on Dun Knock (no visible remains) and a 1st-century Roman camp at Kincladie (part of the rampart and ditch survive in Kincladie Wood). The former is the probable origin of the name Dunning, ex Old Irish dúnán 'little fort'. Legend tells that Saint Serf (fl. 8th century?) killed a dragon here, and there is a thorn tree planted in Jacobite times as well as a monument to Maggie Wall, burnt as a witch in 1657.

The Dunning Parish Historical Society web site (see below) includes St. Serf's Church graveyard survey and Dunning parish census records, both useful for genealogy research. The village (except the church) was burned during the 1715 Jacobite Rebellion. The oldest surviving house (recently restored) dates from the 1730s.
