Herman A. DeVry
Herman Adolf DeVry (November 26, 1876 – March 23, 1941) was an American inventor, aviator, and colleague of Lee de Forest. DeVry is credited with creating the first portable motion picture projector, which he called a ''Theatre in a Suitcase''. He was the founder of the DeVry Company. Early life Herman Adolf DeVry was born on November 26, 1876, in Mecklenburg, Germany. He was the son of Wilhelm Heinrich DeVry (1843–1921) and Kunigunde (1845–1933; born Steuwe). Herman and his family immigrated to the United States in 1886, when he was 10 years old. His father worked as a common laborer, but DeVry wanted to do more with his life. He became interested in photography and film at an early age, an obsession that would continue throughout the rest of his life.Morello, John A."Herman Adolf DeVry."In ''Immigrant Entrepreneurship: German-American Business Biographies, 1720 to the Present'', vol. 4, edited by Jeffrey Fear.

Lee De Forest
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor and a fundamentally important early pioneer in electronics. He invented the first electronic device for controlling current flow; the three-element "Audion" triode vacuum tube in 1906. This started the Electronic Age, and enabled the development of the electronic amplifier and oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications. He had over 300 patents worldwide, but also a tumultuous career— he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin Institute Elliott Cresson Medal and the 1946 American Institute of ...

DeVry University
DeVry University () is a private for-profit university with its headquarters in Naperville, Illinois. It was founded in 1931 by Herman A. DeVry and is accredited by the Higher Learning Commission. DeVry is predominantly an online educator but does have campuses in the United States. History Early history (1931–1970) DeVry was founded in 1931 as the De Forest Training School in Chicago, Illinois. School founder Herman A. DeVry, who had previously invented a motion picture projector and produced educational and training films, named the school after his friend Lee de Forest. De Forest Training School originally taught projector and radio repair, but later expanded to include other electronic equipment such as televisions. After its founder's death in March 1941, the school was renamed DeVry Technical Institute in 1953 and gained accreditation to confer associate degrees in electronics in 1957. Bell & Howell completed its acquisition of DeVry Technical Institute in 1967. A ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mecklenburg
Mecklenburg (; nds, label=Low German, Mękel(n)borg ) is a historical region in northern Germany comprising the western and larger part of the federal-state Mecklenburg-Western Pomerania. The largest cities of the region are Rostock, Schwerin, Neubrandenburg, Wismar and Güstrow. The name Mecklenburg derives from a castle named '' Mikilenburg'' (Old Saxon for "big castle", hence its translation into New Latin and Greek as ), located between the cities of Schwerin and Wismar. In Slavic languages it was known as ''Veligrad'', which also means "big castle". It was the ancestral seat of the House of Mecklenburg; for a time the area was divided into Mecklenburg-Schwerin and Mecklenburg-Strelitz among the same dynasty. Linguistically Mecklenburgers retain and use many features of Low German vocabulary or phonology. The adjective for the region is ''Mecklenburgian'' or ''Mecklenburgish'' (german: mecklenburgisch, link=no); inhabitants are called Mecklenburgians or Mecklenburgers ( ...

Auguste And Louis Lumière
The Lumière brothers (, ; ), Auguste Marie Louis Nicolas Lumière (19 October 1862 – 10 April 1954) and Louis Jean Lumière (5 October 1864 – 6 June 1948), were French manufacturers of photography equipment, best known for their ''Cinématographe'' motion picture system and the short films they produced between 1895 and 1905, which places them among the earliest filmmakers. Their screening of a single film on 22 March 1895 for around 200 members of the "Society for the Development of the National Industry" in Paris was probably the first presentation of projected film. Their first commercial public screening on 28 December 1895 for around 40 paying visitors and invited relations has traditionally been regarded as the birth of cinema. Either the techniques or the business models of earlier filmmakers proved to be less viable than the breakthrough presentations of the Lumières. History The Lumière brothers were born in Besançon, France, to Charles-Antoine Lumière (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omaha–Council Bluffs Metropolitan Area
The Omaha metropolitan area, officially known as the Omaha-Council Bluffs, NE-IA Metropolitan Statistical Area (MSA), is an urbanized region in Nebraska and Iowa in the American Midwest, centered on the city of Omaha, Nebraska. The region consists of eight counties (five in Nebraska and three in Iowa), and extends over a large area on both sides of the Missouri River. Covering and with a population of 967,604 (2020), the Omaha metropolitan area is the most populous in both Nebraska and Iowa (although the Des Moines-West Des Moines MSA is the largest MSA centered entirely in Iowa), and is the 58th most populous MSA in the United States. The 2003 revision to metropolitan area definitions was accompanied by the creation of micropolitan areas and Combined Statistical Areas. Fremont, in Dodge County, Nebraska, was designated a micropolitan area. The Omaha–Council Bluffs–Fremont Combined Statistical Area has a population of 1,058,125 (2020 estimate).

Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Mississippi Exposition
The Trans-Mississippi and International Exposition was a world's fair held in Omaha, Nebraska from June 1 to November 1 of 1898. Its goal was to showcase the development of the entire West, stretching from the Mississippi River to the Pacific Coast. The Indian Congress was held concurrently. Over 2.6 million people came to Omaha to view the 4,062 exhibits during the five months of the Exposition. President William McKinley and William Jennings Bryan were among the dignitaries who attended at the invitation of Gurdon Wattles, the event's leader. 100,000 people assembled on the plaza to hear them speak. The Expo stretched over a tract in North Omaha and featured a -long lagoon encircled by 21 classical buildings that featured fine and modern products from around the world. One reporter wrote, "Perhaps the candid Nebraskan would tell you in a moment of frank contriteness that the prime object of this exposition was to boom Omaha."

35mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film stock supplied by George Eastman. ...

Movie Projector
A movie projector is an optics, opto-mechanics, mechanical device for displaying Film, motion picture film by projecting it onto a movie screen, screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors. (see also digital cinema) Many projectors are specific to a particular film gauge and not all movie projectors are film projectors since the use of film is required. Predecessors The main precursor to the movie projector was the magic lantern. In its most common setup it had a concave mirror behind a light source to help direct as much light as possible through a painted glass picture slide and a lens, out of the lantern onto a screen. Simple mechanics to have the painted images moving were probably implemented since Christiaan Huygens introduced the apparatus around 1659. Initially candles and oil lamps were used, but other light sources, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
