Question: Who, Kenneth Webb or Buster Keaton, was best known for his silent films?

Context paragraphs:
Buster Keaton: Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American actor, comedian, film director, producer, screenwriter, and stunt performer.  He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face."  Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor–director in the history of the movies".  His career declined afterward with a dispiriting loss of his artistic independence when he was hired by Metro-Goldwyn-Mayer and he descended into alcoholism, ruining his family life.  He recovered in the 1940s, remarried, and revived his career to a degree as an honored comic performer for the rest of his life, earning an Academy Honorary Award in 1959.

Steamboat Bill, Jr.: Steamboat Bill, Jr. is a 1928 silent comedy film starring Buster Keaton.  Released by United Artists, the film is the last product of Keaton's independent production team and set of gag writers.  It was not a box-office success and became the last picture Keaton made for United Artists.  Keaton ended up moving to Metro-Goldwyn-Mayer where he made one last film in his trademark style, "The Cameraman", before his creative control was taken away by the studio.

Spite Marriage: Spite Marriage is a 1929 silent comedy film starring Buster Keaton and Dorothy Sebastian.  Keaton and Edward Sedgwick co-directed.  It is the second film Keaton made for MGM and his last silent film, although he wanted it to be a full sound film.  Keaton later wrote gags for some up-and-coming MGM stars like Red Skelton and lifted many gags from this film in his 1943 film "I Dood It", some shot for shot.

The High Sign/One Week: The High Sign/One Week: Music for the Films of Buster Keaton is the seventh album by Bill Frisell to be released on the Elektra Nonesuch label.  It was released in 1995 and features performances by Frisell, Kermit Driscoll and Joey Baron.  The album is designed as accompaniment to Buster Keaton's the first two silent films classic, "The High Sign" (1921) (tracks 1-9) and "One Week" (1920) (tracks 10-19).  It was released at the same time as another album by Frisell of Keaton soundtracks, "" (1995).

Jack Hanlon: Jack Clem Hanlon (February 15, 1916 - December 13, 2012) was an American child actor known for his role in Our Gang and silent films.  According to "Variety", at the time of his death he was the oldest living person to appear in the Our Gang comedies and likely the last surviving cast member of the Buster Keaton silent classic "The General".

Go West: Music for the Films of Buster Keaton: Go West: Music for the Films of Buster Keaton is the sixth album by Bill Frisell to be released on the Elektra Nonesuch label.  It was released in 1995 and features performances by Frisell, Kermit Driscoll and Joey Baron.  The album is designed as accompaniment to the Buster Keaton's silent film classic, "Go West" (1925), and was released at the same time as another album of Keaton soundtracks by Frisell, "The High Sign/One Week" (1995).

Kenneth Webb: Kenneth S. Webb (October 16, 1892 in New York City – March 23, 1966 in Hollywood, California) was an American film director, screenwriter, and composer noted for directing a number of films in the early age of the American film industry.  He helped write the "Gay Divorce" along with Samuel Hoffenstein.

Three Ages: Three Ages is a 1923 black-and-white American feature-length silent comedy film starring comedian Buster Keaton and Wallace Beery.  The first feature Keaton wrote, directed, produced, and starred in (unlike "The Saphead" (1920), in which he only acted), Keaton structured the film like three inter-cut short films.  The structure also worked as a satire of D. W. Griffith's 1916 film "Intolerance".  The film was shot in this manner as a kind of insurance for the studio.  While Keaton was a proven success in the short film medium, he had yet to prove himself as a feature-length star.  Had the project flopped, the film would have been broken into three short films, each covering one of the 'Ages.'

Buster Keaton Rides Again: Buster Keaton Rides Again is a 55-minute 1965 documentary film directed by John Spotton and narrated by Michael Kane.  The film is a behind-the-scenes documentary shot while Buster Keaton's film "The Railrodder" (1965), was being produced.  Although it is a production documentary, the film is actually longer than "The Railrodder", which was only 24 minutes long.  Both films were produced by the National Film Board of Canada (NFB).  In addition, a French version of "Buster Keaton Rides Again", "Avec Buster Keaton" was released.

Charles Bowers: Charles R. Bowers (June 7, 1889 – November 26, 1946) was an American cartoonist and slapstick comedian during the silent film and early "talkie" era.  He was forgotten for decades and his name was notably absent from most histories of the Silent Era, although his work was enthusiastically reviewed by André Breton and a number of his contemporaries.  As his surviving films have an inventiveness and surrealism which give them a freshness appealing to modern audiences, after his rediscovery his work has sometimes been placed in the "top tier" of silent film accomplishments (along with those of, for example, Charlie Chaplin, Buster Keaton, Harold Lloyd).  In comic style, he probably modelled himself after both Harry Langdon and Buster Keaton and was known to the French as ""Bricolo"."
