Context paragraphs:
List of Judson Dance Theater performers: Judson Dance Theater was an informal group of dancers who performed at the Judson Memorial Church in Greenwich Village, Manhattan New York City between 1962 and 1964.  It grew out of a dance composition class taught by Robert Dunn, a musician who had studied with John Cage.  The artists involved were "avant garde" experimentalists who rejected the confines of Modern dance practice and theory, inventing as they did the precepts of Postmodern dance.

Judson Dance Theater: Judson Dance Theater was a collective of dancers, composers, and visual artists who performed at the Judson Memorial Church in Greenwich Village, Manhattan New York City between 1962 and 1964.  It grew out of a composition class taught by Robert Dunn, a musician who had studied with John Cage.  The artists involved were "avant garde" experimentalists who rejected the confines of Modern dance practice and theory, inventing as they did the precepts of Postmodern dance.  Yvonne Rainer's 'No Manifesto' - (to which she rejects any confines to technique, thrill, spectacle, glamour, or assumed space) came out of this movement as a way to state what the Judson Dance Theater wanted; a way to convey the beauty of ordinary movement and the pureness of dance/performance art.  It was a place for collaboration between artists in various fields such as, dancers, writers, filmmakers, composers, etc.  Their goal in this collaboration was to observe dance in its purist form.  This resulted in the elimination of many theatrical elements like plots and storylines, elaborate costumes and scenery, and even formal dance technique.  The group constantly redefined itself by these collaborative efforts.

Judson Memorial Church: The Judson Memorial Church is located on Washington Square South between Thompson Street and Sullivan Street, opposite Washington Square Park, in the Greenwich Village neighborhood of the New York City borough of Manhattan.  It is affiliated with the American Baptist Churches USA and with the United Church of Christ.

Eleanor Campbell (physician): Eleanor Anderson Campbell (1878–1959, née Eleanor Milbank Anderson) was the founder and director of the Judson Health Center (1921), a health and dental clinic serving residents of the lower west side of New York City.  First located in the basement of the Judson Memorial Church south of Washington Square, by 1924 the Center was the largest clinic of its kind in the United States.  The Center provided healthcare through over one million visits to the largely Italian immigrant population between 1921 and 1957, when Campbell retired.  Campbell refused any wages for her services.  In 1957, Dr. Campbell was awarded the Star of Italian Solidarity by the Italian government for her contributions to Italian-Americans.

Edward Judson: Edward Judson (1844-1914) was an American Baptist clergyman, born at Maulmain, British Burma, a son of the missionary Adoniram Judson and his second wife, Sarah Hall Boardman.  He graduated in 1863 at Brown University, in 1868 was appointed professor of Latin and modern languages in Madison (now Colgate) University, in 1874-75 traveled abroad, and after being ordained to the Baptist ministry in the latter year was pastor of a church at Orange, N. J., until 1881.  Thereafter to the time of his death he occupied the pulpit of a New York City church, first known as the Berean Church, later as the Memorial Baptist, and finally as the Judson Memorial, Dr. Judson having erected a large building on Washington Square to house the congregation, equipped with the facilities of an "institutional" church.  He lectured on theology at the University of Chicago (1904-06) and on Baptist principles and polity at Union Theological Seminary (1906-08) and was made professor of pastoral polity at Colgate.  In 1899 he published a "Life" of his father, and he wrote also "The Institutional Church".

Downtown music: Downtown music is a subdivision of American music, closely related to experimental music.  The scene the term describes began in 1960, when Yoko Ono, one of the early Fluxus artists, opened her loft at 112 Chambers Street, in a part of Lower Manhattan later named Tribeca, to be used as a performance space for a series curated by La Monte Young and Richard Maxfield.  Prior to this, most classical music performances in New York City occurred "uptown" around the areas that the Juilliard School at Lincoln Center and Columbia University would soon occupy.  Ono's gesture led to a new performance tradition of informal performances in nontraditional venues such as lofts and converted industrial spaces, involving music much more experimental than that of the more conventional modern classical series Uptown.  Spaces in Manhattan that supported Downtown music from the 1960s on included the Judson Memorial Church, The Kitchen, Experimental Intermedia, Roulette, the Knitting Factory, Dance Theater Workshop, Tonic, the Gas Station, the Paula Cooper Gallery, and others.  Brooklyn Academy of Music has also shown a predilection for composers from the Downtown scene.
