Context: Patrick McGuigan (March 17, 1868 – September 13, 1938), commonly known as "Paddy" McGuigan, was an American boxer, promoter, entertainer, business man, and sports figure in the late nineteenth and early twentieth centuries.  A member of the NJ Boxing Hall of Fame, he is considered one of the best fighters of the era and was a beloved figure among sports fans in the region, considered by many to be "The Pride of New Jersey."  He became the New Jersey Lightweight Champion in 1890 and the Interstate New York & New Jersey Lightweight Champion in 1892.  Fighting in both the bare-knuckle and gloved eras, he met virtually all of the world's top boxers in his class.  At the peak of his career he traveled the country with William Muldoon's athletic carnival, "meeting all comers" in each city they visited.  Once he retired from boxing professionally, he became a promoter and opened a fight club and a saloon in Harrison, NJ.  He has been credited as one of the men responsible for boxing's rise to affluence in New Jersey after it was legalized in 1918 under the Hurley Law, being the first individual in the state to secure a license to legally host boxing matches.  Paddy "must be chronicled as one of the greatest ringmen who ever lived," according to sportswriter Anthony Marenghi, and has been described by Hall of Fame manager Tom O'Rourke as the greatest fighter he had ever seen. William Claude Dukenfield (January 29, 1880 – December 25, 1946), better known as W. C. Fields, was an American comedian, actor, juggler and writer.  Fields' comic persona was a misanthropic and hard-drinking egotist, who remained a sympathetic character despite his snarling contempt for dogs and children. The Bush Temple of Music, at 100 West Chicago Avenue in Chicago, was built in 1901 as the headquarters and showroom of the Bush and Gerts Piano Company, one of Chicago’s leading piano companies.  Designed by architect J.E.O. Pridmore, the building is an example of the importance of piano manufacturing and sales during the late 19th and early 20th centuries when Chicago was the leading piano manufacturing center in the world.  The building is a rare large-scale example of French Renaissance Revival-style architecture, an unusual style in Chicago and the United States.  The building’s design and decorative details are unique examples of the historic revival style favored by Chicagoans in the late nineteenth and early twentieth centuries.  The building was designated a Chicago Landmark on June 27, 2001.  It is being considered for listing on the National Register of Historic Places. Sherman Houston Dudley (1872 – March 1, 1940) was an African-American vaudeville performer and theatre entrepreneur.  He gained notability in the late nineteenth and early twentieth century as an individual performer, a composer of ragtime songs, and as a member and later owner of various minstrel shows including the Smart Set.  Dudley is also notable as one of the first African Americans to combine business with theater, by starting a black theater circuit, in which theaters were owned or operated by African Americans and provided entertainment by and for African Americans. Edwin Othello Excell (December 13, 1851 – June 10, 1921), commonly known as E. O.

Sato (March 13, 1871 - March 23, 1921) was an American vaudeville performer who flourished in the late nineteenth and early twentieth centuries.  His act was notable for its juggling of the comedic style and may be described as helping define the so-called "tramp" juggling style epitomized by W. C. Fields.  In fact, Sato and Fields are known from Fields' surviving correspondence to have maintained a bantering relationship in which the two traded gossip and ideas for their acts. In Australia, tram networks were developed to provide public transport in many of the country's cities and towns in the late nineteenth and early twentieth centuries.  As the twentieth century wore on, trams fell out of favour and most networks closed or were severely cut back.  A revival in the late twentieth and early twenty-first centuries has seen trams return to some of the larger cities and existing networks extended.
