The Benton Review is a weekly newspaper serving Benton, Jasper, Newton, Tippecanoe, Warren and White counties in Indiana.
 It began July 1875 as the "Benton Democrat"; by 1902 it was bought by George Roby as the "Benton Review", and he combined it with the "Fowler Leader" in 1914.
 The paper's masthead describes it as a combination of the "Fowler Leader" (founded 1893 by John P. Carr) and the "Fowler Republican".
Dempster McIntosh was born in Newport, Rhode Island, on 17 January 1896.
 At age seven, his family moved to Cotuit, Massachusetts, a small fishing village on Cape Cod, where his father was a gardener on the Rothwell estate.
 In those preadolescent years, he worked as a laborer in the summertime and was generally known as "a jovial figure."
 In 1908, the McIntoshes moved to Pittsburgh, Pennsylvania, where, at the age of 15, he stopped attending school and began working.
 However, Cotuit historian and biographer Albert Crocker Knight, author of McIntosh's biography, "From Ocean View Avenue to Embassy Row", has often said that it was the village, with its bustling commerce, rather than Pittsburgh, that sparked Dempster's interest in business.
 Indeed, in an article titled by "The Barnstable Patriot", Knight was quoted as bestowing McIntosh with the title of "Cotuit's own Horatio Alger."
 In 1915, after having dropped out of school for some years, he completed a Money and Banking course at the University of Pittsburgh.
Dempster Brothers, Inc. of Knoxville, Tennessee, was an industrial firm that made waste handling vehicles including the Dempster Dumpmaster and Dempster Dinosaur.

Orton Caswell "Cas" Walker (March 23, 1902 – September 25, 1998), was a Tennessee businessman, politician, and personality on television and radio.
 Walker founded a successful chain of small grocery stores that grew to include several dozen stores scattered throughout the Knoxville, Tennessee vicinity as well as parts of Virginia and Kentucky.
 From 1941 through 1971, Walker served on the Knoxville city council where he became legendary for his uncompromising political stances and his vehement opposition to what he claimed was a corrupt elitism in the city's government.
 "The Cas Walker Farm and Home Hour", a local variety show sponsored by Walker, ran in various radio and television formats between 1929 and 1983 and helped launch the careers of entertainer Dolly Parton and the Everly Brothers.
The Tragedy of Man (Hungarian: "Az ember tragédiája" ) is a play written by the Hungarian author Imre Madách.
 It was first published in 1861.
 The play is considered to be one of the major works of Hungarian literature and is one of the most often staged Hungarian plays today.
 Many lines have become common quotations in Hungary.
 The 1984 film "The Annunciation" ("Angyali üdvözlet") was based on the play, as was the 2011 animated film "The Tragedy of Man".
Anti-prom also known as morp ("prom" spelled in reverse) is a social event often staged by high school students as a protest against, or boycott of, their school's official prom, as an alternative celebration.
 Other times, it may be an unofficial prom, planned by the students themselves so that it is not under the control of the school.
OOzeball is an annual mud volleyball tournament, a tradition at many universities that originated at the University of Connecticut in 1984.

Reza Abdoh (February 23, 1963 in Tehran, Iran – May 12, 1998 in New York City) was an Iranian-born American director and playwright known for large-scale, experimental theatrical productions, often staged in unusual spaces like warehouses and abandoned buildings.
George Roby Dempster (September 16, 1887 – September 18, 1964) was an American businessman, inventor, and politician, active primarily in Knoxville, Tennessee, during the first half of the twentieth century.

 During the 1910s and 1920s, the Dempster Brothers Construction Company, operated by Dempster and his brothers, built a number of roads and railroads across the Southern Appalachian region.
 Dempster also served as a city manager and mayor of Knoxville, where he became legendary for his political battles with eccentric Knoxville businessman Cas Walker and "Knoxville Journal" editor Guy Smith, Jr.
