Frances Lee (May 5, 1906 – November 5, 2000) was an American film actress during Hollywood's silent film era, and well into the sound film era of the 1930s.
Virginia Valli (June 10, 1898 – September 24, 1968) was an American stage and film actress whose motion picture career started in the silent film era and lasted until the beginning of the sound film era of the 1930s.
Enrico Cocozza (6 November 1921 – 27 December 1997), was a Scottish filmmaker who won many film awards during the 1940s and 1950s.
 His often surreal films were mainly filmed in and around the town of Wishaw in Scotland, where his family owned the popular Belhaven Cafe.
 These include "Chick's Day" (1950), a prize winner at the 1951 Scottish Amateur Film Festival, "The Living Ghost" (1957), and "Glasgow's Docklands" (1959).
 Illness later forced him to give up making films and he spent most of his working life teaching at the University of Strathclyde in Glasgow.
 In 2001 he was the subject of the Channel 4 documentary "Artery: the Story of Enrico Cocozza".
Robert F. Hill (April 14, 1886 – March 18, 1966) was a Canadian film director, screenwriter, and actor during the silent film era.
The Robert F. Kennedy Awards for Excellence in Journalism is a journalism award named after Robert F. Kennedy and awarded by the Robert F. Kennedy Center for Justice and Human Rights.
 The annual awards are issued in several categories and were established in December 1968 by a group of reporters who covered Kennedy's campaigns.
 Winners are judged by more than 50 journalists each year, led by a committee of six independent journalists.
 The awards honor reporting "on issues that reflect Robert F. Kennedy's concerns, including human rights, social justice and the power of individual action in the United States and around the world.
 Entries include insights into the causes, conditions and remedies of injustice and critical analysis of relevant public policies, programs, attitudes and private endeavors."
 The awards are known as the "poor people's Pulitzers" in media circles.
William Sidney "Will" Stanton (September 18, 1885 – December 18, 1969) was an American character actor, whose career spanned the first twenty-five years of the sound film era.
 Born in London, England, Stanton broke into the film industry at the very tail end of the silent film era in 1927, appearing in several film shorts for Hal Roach Studios.
 He would debut in a feature film with a small role in Raoul Walsh's 1928 silent film, "Sadie Thompson", starring Gloria Swanson, Lionel Barrymore, and Walsh.
 During the following 20 years he would appear in another 70 films, mostly in small and supporting roles.

A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue.
 The silent film era lasted from 1895 to 1936.
 In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards with a written indication of the plot or key dialogue.
 The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was made practical only in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system.
 During silent films, a pianist, theater organist, or, in large cities, even a small orchestra would often play music to accompany the films.
 Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music.
John Gilbert (born John Cecil Pringle; July 10, 1899 – January 9, 1936) was an American actor, screenwriter and director.
 He rose to fame during the silent film era and became a popular leading man known as "The Great Lover".
 At the height of his career, Gilbert rivaled Rudolph Valentino, another silent film era leading man, as a box office draw.
