Question: Doris Batcheller Humphrey (October 17, 1895 – December 29, 1958) was a dancer and choreographer of the early twentieth century, along with her contemporaries Martha Graham, and Katherine Mary Dunham (also known as Kaye Dunn) was an American dancer, choreographer, author, educator, and social activist, born on which date?
Context: Giuseppe Sergi (March 20, 1841 – October 17, 1936) was an influential Italian anthropologist of the early twentieth century, best known for his opposition to Nordicism in his books on the racial identity of ancient Mediterranean peoples.  He rejected existing racial typologies that identified Mediterranean peoples as "dark whites" because they implied a Nordicist conception of Mediterranean peoples descending from whites who had become racially mixed with non-whites which he claimed was false.  His concept of the Mediterranean race, identified Mediterranean peoples as being an autonomous brown race and he claimed that the Nordic race was descended from the Mediterranean race whose skin had depigmented to a pale complexion after it moved north.  This concept became important to the modelling of racial difference in the early twentieth century. Bertram Ross (November 14, 1920 – April 20, 2003) was an American dancer best known for his work with the Martha Graham Dance Company, with which he performed for two decades.  He was Martha Graham’s longtime dance partner and the originator of male roles in most of her major ballets from the 1950s and 1960s, including Adam in Embattled Garden, and both Agamemnon and Orestes in Clytemnestra.  After leaving Graham's company, Ross taught, choreographed and formed his own dance company.  In later life, he toured in a cabaret duo with his real life partner, the composer and pianist John Wallowitch. Katherine Mary Dunham (also known as Kaye Dunn, June 22, 1909 – May 21, 2006) was an American dancer, choreographer, author, educator, and social activist.  Dunham had one of the most successful dance careers in American and European theater of the 20th century, and directed her own dance company for many years.  She has been called the "matriarch and queen mother of black dance." Talley Beatty (22 December 1918 – 29 April 1995) was born in Cedar Grove, Louisiana, a section of Shreveport, but grew up in Chicago, Illinois.  He is considered one of the greatest of African American choreographers, and also bears the titles dancer, educator, and dance company director.  After studying under Katherine Dunham and Martha Graham, Beatty went on to do solo work and choreograph his own works which center on the social issues, experiences, and everyday life of African Americans.  Beatty and his technique and style of dancing have been both praised and criticized by critics and dancers of his day. Stuart Hodes (born 1924) is an American dancer, choreographer, dance teacher, dance administrator and author.  He was Martha Graham’s partner, danced on Broadway, in TV, film, in recitals, and with his own troupe.  His choreography has appeared on the Boston Ballet, Dallas Ballet, Harkness Ballet, Joffrey Ballet, San Francisco Ballet and other troupes.  He taught at the Martha Graham School, Neighborhood Playhouse, NYC High School of Performing Arts, headed dance at NYU School of the Arts and Borough of Manhattan Community College.  He was Dance Associate for the NY State Council on the Arts, dance panelist for the National Endowment for the Arts, president of the National Association of Schools of Dance, and a member of the First American Dance Study Team to China in 1980, returning in 1992 to teach the Guangzhou modern dance troupe. Lucas Hoving (September 5, 1912 – January 5, 2000) was a modern dancer, choreographer and teacher most famous for the roles he created as an original member of the José Limón Dance Company.  Hoving performed opposite Limón in several of the company's best known works, including "The Moor's Pavane" (1949), "The Traitor" (1954), and "Emporer Jones" (1956).  He also danced in works by seminal modern dance figures Kurt Jooss, Martha Graham, Agnes De Mille, Doris Humphrey, and Helen Tamiris before forming his own company in 1961. Peter Randazzo (born January 2, 1943, in Brooklyn) is an American dancer and choreographer known for his contributions to modern dance.  From 1962–1968 he was a principal dancer with the Martha Graham Dance Company.  In 1968 he co-founded the Toronto Dance Theatre (TDT) and its associated school, The School of Toronto Dance Theatre, with fellow Martha Graham disciples Patricia Beatty and David Earle.  A prolific choreographer, the TDT has featured his works in performances internationally for more than 40 years. Doris Batcheller Humphrey (October 17, 1895 – December 29, 1958) was a dancer and choreographer of the early twentieth century.  Along with her contemporaries Martha Graham and Katherine Dunham, Humphrey was one of the second generation modern dance pioneers who followed their forerunners – including Isadora Duncan, Ruth St. Denis and Ted Shawn – in exploring the use of breath and developing techniques still taught today.  As many of her works were annotated, Humphrey continues to be taught, studied and performed. Blakeley White-McGuire (born October 28, 1974 in Baton Rouge, Louisiana, is an award-winning dancer, choreographer, répétiteur, and educator.  She is a Principal Guest Artist and former Principal Dancer of Martha Graham Dance Company.  Described by Gia Kourlas of the "New York Times" in 2007 as having a "powerful technique and dramatic instinct with an appealing modern spunk", White-McGuire has received widespread critical acclaim as a Graham dancer. Mellie Dunham (July 29, 1853 - September 27, 1931) was an American fiddler during the early twentieth century.  Dunham was born in Norway Maine, the son of Alanson Mellen Dunham and Christiana Bent.  He came to prominence after he was invited to play for Henry Ford at his house in Dearborn, Michigan.  Ford sent a Pullman car for Dunham and his wife, Emma "Gram" Dunham (née Richardson), because of Ford's love of country music.  While Ford had invited 38 other fiddlers before Dunham, none received as much attention as Dunham did.
