Günter Rössler (January 6, 1926 in Leipzig – December 31, 2012 in Leipzig) was a German photographer who made a name for himself especially in the field of nude art photography.
 A pioneer of nude photography in East Germany and notable fashion photographer, Rössler was often referred to by the media as the "Helmut Newton of East Germany", stylized since Playboy published in 1984 a photo-gallery titled: "Mädchen der DDR" (Girls of the GDR).
 Rössler however, never liked this comparison with Newton, saying: "with Newton the pose dominates, with me it is about the highest possible authenticity of the girls".
 Rössler significantly contributed to the history of German photography in the second half of the twentieth century, earning him recognition not only as a great photographer, but also as the "old master of German nude photography".
Frederick S. Armitage (Seneca Falls, NY, June 29, 1874 – Ecorse, MI, January 3, 1933) was an early American motion picture cinematographer and director, working primarily for the American Mutoscope and Biograph Company.
 Often identified as "F.S. Armitage" in AM&B paperwork, Armitage had a hand in creating more than 400 often very short subjects for AM&B in the days where its films were made as much for the hand-crank operated Mutoscope device as for projection.
 Several of Armitage's subjects stand out from the company's regular routine of actualities and comic skits in their innovative use of camerawork, superimpositions, time-lapse photography and other effects then new to the art of film-making.
The Vancouver School of conceptual or post-conceptual photography (often referred to as photoconceptualism) is a loose term applied to a grouping of artists from Vancouver starting in the 1980s.
 Critics and curators began writing about artists reacting to both older conceptual art practices and mass media by countering with "photographs of high intensity and complex content that probed, obliquely or directly, the social force of imagery."
 No formal "school" exists and the grouping remains both informal and often controversial even amongst the artists themselves, who often resist the term.
 Artists associated with the term include Vikky Alexander, Roy Arden, Ken Lum, Jeff Wall, Ian Wallace, Stan Douglas and Rodney Graham.
Sy Kattelson (born Seymour Kattelson; February 11, 1923 in New York City, New York) is an American photographer whose earliest work documents working class New Yorkers during the years immediately following World War Two.
 He was an early practitioner of street photography and was associated with the Photo League from 1947 until its closing in 1951.
 His portraits, frequently taken without his subjects' awareness while traveling through the streets or riding the city's subways, convey the dignity of their lives as lived in public places.
 The depth of his photographs often comes from the tension between the grittiness of their urban settings and the contemplative sense of his subjects' as being lost within themselves.
David Mordecai (1909-1973) was an Indian photographer in Calcutta whose subjects included the Nehrus, Tenzing Norgay, Sir Edmund Hillary, and King Mahendra and Queen Ratna of Nepal.
Led by Edouard Wyss-Dunant, the 1952 Swiss Mount Everest expedition saw Raymond Lambert and Sherpa Tenzing Norgay reach a height of about 8595 m on the southeast ridge, setting a new climbing altitude record, opening up a new route to Mount Everest and paving the way for further successes by other expeditions.
Wallace George Lowe, CNZM, OBE (15 January 1924 – 20 March 2013), known as George Lowe, was a New Zealand-born mountaineer, explorer, film director and educator.
 He was the last surviving member of the 1953 British Mount Everest Expedition, during which his friend Edmund Hillary and Sherpa Tenzing Norgay became the first known people to summit the world's highest peak.
Raymond Lambert (18 October 1914 – 24 February 1997) was a Swiss mountaineer, who with Sherpa Tenzing Norgay reached an altitude of 8611 metres (just 237 metres from the summit) of Mount Everest in May 1952.
 At the time it was the highest point that a climber had ever reached.
 There was a second Swiss expedition in autumn 1952, but a party including Lambert and Tenzing was forced to turn back at a slightly lower point.
 The following year Tenzing returned with Edmund Hillary to reach the summit on 29 May 1953.
Tenzing Norgay OSN GM ( ; Sherpa: བསྟན་འཛིན་ནོར་རྒྱས "tendzin norgyé"; 29 May 1914 – 9 May 1986), born Namgyal Wangdi and often referred to as Sherpa Tenzing, was an Indian and Nepali Sherpa mountaineer.
 He was one of the first two individuals known to reach the summit of Mount Everest, which he accomplished with Edmund Hillary on 29 May 1953. "
Time" named him one of the people of the 20th century.
Barkley L. Hendricks (April 16, 1945 – April 18, 2017) was a contemporary American painter who made pioneering contributions to black portraiture and conceptualism.
 While he worked in a variety of media and genres throughout his career (from photography to landscape painting), Hendricks' best known work took the form of life-sized painted oil portraits.
 In these portraits, he attempted to imbue a proud, dignified presence upon his subjects.
 He frequently painted black Americans against monochrome interpretations of urban northeastern American backdrops.
 Hendricks' work is unique for its marriage of American realism and post-modernism.
 Although Hendricks did not pose his subjects as celebrities, victims, or protesters, the subjects depicted in his works were often the voices of the under-represented blacks of the 1960s and 1970s.
 Hendricks even stood alongside his subjects and featured himself in works, like in "Brilliantly Endowed (Self portrait)", 1977 where he painted himself nude in response to an art critic's comments on his show.
