Joseph A. Ball

Joseph Arthur Ball (August 16, 1894 – August 27, 1951) was an American inventor, physicist, and executive at Technicolor. He was the technical director of the first color movie Becky Sharp, and a recipient of an Academy Honorary Award at the 11th Academy Awards for his contributions to color film photography. He held many patents in color photography and was credited with creating the three-component process.[1][2][3]

Angénieux retrofocus

The Angénieux retrofocus photographic lens is a wide-angle lens design that uses an inverted telephoto configuration. The popularity of this lens design made the name retrofocus synonymous with this type of lens. The Angénieux retrofocus for still cameras was introduced in France in 1950 by Pierre Angénieux.

International Workshop on Operator Theory and its Applications

International Workshop on Operator Theory and its Applications (IWOTA) was started in 1981 to bring together mathematicians and engineers working in operator theoretic side of functional analysis and its applications to related fields. These include:

Differential equations and Integral equations

Complex analysis and Harmonic analysis

Linear system and Control theory

Mathematical physics

Signal processing

Numerical analysisThe other major branch of operator theory, Operator algebras (C* and von Neumann Algebras), is not heavily represented at IWOTA and has its own conferences.

IWOTA gathers leading experts from all over the world for an intense exchange of new results, information and opinion, and for tracing the future developments in the field. The IWOTA meetings provide opportunities for participants (including young researchers) to present their own work in invited and contributed talks, to interact with other researchers from around the globe, and to broaden their knowledge of the field.

In addition, IWOTA emphasizes cross-disciplinary interaction among mathematicians, electrical engineers and mathematical physicists. In the even years, the IWOTA workshop is a satellite meeting to the biennial International Symposium on the Mathematical Theory of Networks and Systems (MTNS). From the humble beginnings in the early 80's, the IWOTA workshops grew to become one of the largest continuing conferences attended by the community of researchers in operator theory.

Joseph A. Ball (mathematician)

Joseph Anthony Ball (born 4 June 1947) is an American mathematician who is currently a professor emeritus at the Virginia Polytechnic Institute and State University, often referred to as Virginia Tech. He is a 2019 fellow of the American Mathematical Society for contributions to operator theory, analytic functions, and service to the profession .

He was awarded Bachelor of Science from Georgetown University in 1969. He obtained his Master of Science in 1970 and Doctor of Philosophy in 1973 both from the University of Virginia, Charlottesville. The title of his doctoral dissertation is "Unitary Perturbations of

Contractions", supervised by Marvin Rosenblum. According to current Mathematics Genealogy Project database, Ball has 12 students and 18 descendants.

Lee Bowers

Lee Edward Bowers Jr. (January 12, 1925 – August 9, 1966) was a witness to the assassination of John F. Kennedy in Dallas, Texas on November 22, 1963.

The timing and circumstances of Bowers' death have led to various allegations that his demise was part of a cover-up subsequent to the Kennedy murder.

List of color film systems

This is a list of color film processes known to have been created for photographing and exhibiting motion pictures in color since the first attempts were made in the late 1890s. It is limited to "natural color" processes, meaning processes in which the color is photographically recorded and reproduced rather than artificially added by hand-painting, stencil coloring, or other arbitrary "colorization" methods.

Stephen Collins

Stephen Weaver Collins (born October 1, 1947) is an American actor and writer. He is known for playing Eric Camden on the long-running television series 7th Heaven from 1996 to 2007. Since then, Collins has played the roles of Dr. Dayton King on the ABC TV series No Ordinary Family and Dr. Gene Porter in the television series Revolution, father of Elizabeth Mitchell's character, Rachel Matheson. Before 7th Heaven, Collins was known for his role as Commander Willard Decker in the 1979 film Star Trek: The Motion Picture.

In 2014, Collins admitted to sexually abusing three different underage girls between 1973 and 1994.

Technicolor

Technicolor is a series of color motion picture processes, the first version dating to 1916, and followed by improved versions over several decades.

It was the second major color process, after Britain's Kinemacolor, and the most widely used color process in Hollywood from 1922 to 1952. Technicolor became known and celebrated for its highly saturated color, and was initially most commonly used for filming musicals such as The Wizard of Oz (1939) and Down Argentine Way (1940), costume pictures such as The Adventures of Robin Hood (1938) and Gone with the Wind (1939), and animated films such as Snow White and the Seven Dwarfs (1937), Gulliver's Travels (1939), and Fantasia (1940). As the technology matured it was also used for less spectacular dramas and comedies. Occasionally, even a film noir—such as Leave Her to Heaven (1945) or Niagara (1953)—was filmed in Technicolor.

"Technicolor" is the trademark for a series of color motion picture processes pioneered by Technicolor Motion Picture Corporation (a subsidiary of Technicolor, Inc.), now a division of the French company Technicolor SA. The Technicolor Motion Picture Corporation was founded in Boston in 1914 (incorporated in Maine in 1915) by Herbert Kalmus, Daniel Frost Comstock, and W. Burton Wescott. The "Tech" in the company's name was inspired by the Massachusetts Institute of Technology, where both Kalmus and Comstock received their undergraduate degrees and were later instructors. Technicolor, Inc. was chartered in Delaware in 1921. Most of Technicolor's early patents were taken out by Comstock and Wescott, while Kalmus served primarily as the company's president and chief executive officer.

Warren Commission

The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established by President Lyndon B. Johnson through Executive Order 11130 on November 29, 1963 to investigate the assassination of United States President John F. Kennedy that had taken place on November 22, 1963. The U.S. Congress passed Senate Joint Resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy, mandating the attendance and testimony of witnesses and the production of evidence. Its 888-page final report was presented to President Johnson on September 24, 1964 and made public three days later. It concluded that President Kennedy was assassinated by Lee Harvey Oswald and that Oswald acted entirely alone. It also concluded that Jack Ruby acted alone when he killed Oswald two days later. The Commission's findings have proven controversial and have been both challenged and supported by later studies.

The Commission took its unofficial name—the Warren Commission—from its chairman, Chief Justice Earl Warren. According to published transcripts of Johnson's presidential phone conversations, some major officials were opposed to forming such a commission and several commission members took part only reluctantly. One of their chief reservations was that a commission would ultimately create more controversy than consensus.
