John H. McCullagh (1842 – March 6, 1893) was an American law enforcement officer and police captain in the New York City Police Department.

 He especially confronting the latter gang when their leaders Ike Marsh and Dutch Heinrichs began raiding the Hudson River Railroad yards and express trains.

The former Adams County Jail, also known as the House of History: Adams County Historical Society, is located in Corning, Iowa, United States.

 The two-story rectangular building is a Vernacular style structure with Greek Revival influence.
 It is capped with a hipped roof and a flat crest.
 It served the county for the next 78 years as its jailhouse.
 The building also provided residential space on the lower level to the sheriff, or if he had his own house, to the jailer.
 The upper floor held the cells.
 The most notable event at the jail was the lynching of local farmer John W. McKenzie in 1887, who had shot his neighbor.
 The building was converted into apartments in 1955, and a museum in 1969.

 From 1843 to 1845 he was a member of the New South Wales Legislative Council.
Prophet's Prey is a 2015 American documentary film directed by Amy J. Berg.
 The film is an adaptation of the 2011 book "Prophet's Prey: My Seven-Year Investigation into Warren Jeffs and the Fundamentalist Church of Latter-Day Saints".

"Farmer John" is a song written by Don "Sugarcane" Harris and Dewey Terry, and first recorded by the two as the American R&B duo Don and Dewey, in 1959.
 Although the original version of the composition did not receive much attention, it was reinvigorated by the garage rock band the Premiers, whose raving cover version was released in 1964.
 The song's raw and partying atmosphere was immensely popular, reaching number 19 on the "Billboard" Hot 100.
 Following the group's national success, several additional interpretations of "Farmer John" were released, making the tune a classic of garage rock.
The actuality film is a non-fiction film genre that, like the documentary film, uses footage of real events, places, and things, yet unlike the documentary is not structured into a larger argument, picture of the phenomenon or coherent whole.
 In practice, actuality films preceded the emergence of the documentary.
 During the era of early cinema, actualities—usually lasting no more than a minute or two and usually assembled together into a program by an exhibitor—were just as popular and prominent as their fictional counterparts.
 The line between "fact" and "fiction" was not so sharply drawn in early cinema as it would become after the documentary came to serve as the predominant non-fiction filmmaking form.
 An actuality film is not like a newspaper article so much as it is like the still photograph that is published along with the article, with the major difference being that it moves.
 Apart from the traveling actuality genre, actuality is one film genre that remains strongly related to still photography.
The Real Dirt on Farmer John is a 2005 documentary film directed by Taggart Siegel about the life of Midwestern farmer John Peterson, operator of Angelic Organics.

 The album cover was shot in front of the huge mural adorning the wall of The Farmer John Company, (also seen in the movie "Carrie"), located at Soto Street and Vernon in Vernon, California.
 The album was on the Billboard 200 charts for eleven weeks, charting as high as #112 on June 24, 1972.
Stanley Kubrick's Boxes is a 2008 documentary film directed by Jon Ronson about the film director Stanley Kubrick.
 Ronson's intent was not to create a biography of the filmmaker but rather to understand Kubrick by studying the director's vast personal collection of memorabilia related to his feature films.
 The documentary came about in 1998 when Ronson received a request from Kubrick's estate for a copy of a documentary Ronson made about the Holocaust (Ronson was unaware that it was Kubrick who was asking for the film until months later).
 A year later, as Ronson was making plans to conduct a rare interview with the director, Kubrick suddenly died after completing work on his final film "Eyes Wide Shut".
 To his surprise, Ronson was invited to Kubrick's house by his widow.
 When he arrived, he found that half the house was filled by more than one thousand boxes containing snap shots, newspaper clippings, film out-takes, notes, and fan letters which the director used for research towards each of his films.
