invited him to join her company. In 1939, Cunningham moved to New York City and danced as a soloist in the Martha Graham Dance Company for six years. He presented his first solo concert in New York in April 1944 with composer John Cage, who became his lifelong romantic partner and frequent collaborator until Cage's death in 1992. In the summer of 1953, as a teacher in residence at Black Mountain College, Cunningham formed the Merce Cunningham Dance Company. Throughout his career, Cunningham choreographed more than 200 dances and over 800 Events, or site-specific choreographic works. In 1963 he joined with Cage to create the Walker Art Center's first performance, instigating what would be a 25-year collaborative relationship with the Walker. In his performances, he often used the I Ching to determine the sequence of his dances and, often, dancers were not informed of the order until the night of the performance. In addition to his role as choreographer, Cunningham performed as a dancer in his company into the early 1990s. In 1968 Cunningham published his book Changes: Notes on Choreography, edited by Francis Starr, containing various sketches of his choreography. Cunningham continued to live in New York City and lead his dance company as Artistic Director until his death. He presented his last work, a new work, Nearly Ninety, in April 2009, at the Brooklyn Academy of Music, New York, to mark his 90th birthday. Later that year he died in his home at the age of 90. Merce Cunningham Dance Company Cunningham formed Merce Cunningham Dance Company (MCDC) at Black Mountain College in 1953. Guided by its leader's radical approach to space, time and technology, the company has forged a distinctive style, reflecting Cunningham's technique and illuminating the near limitless possibility for human movement. The original company included dancers Carolyn Brown, Viola Farber, Marianne Preger-Simon, Paul Taylor, and Remy Charlip, and musicians John Cage and David Tudor. In 1964 the Cunningham Dance Foundation was established to support his work. MCDC made its first international tour in 1964, visiting Europe and Asia. From 1971 until its dissolution in 2012, the company was based in the Westbeth Artists Community in the West Village; for a time Cunningham himself lived a block away at 107 Bank Street, with John Cage. On July 20, 1999, Merce Cunningham and Mikhail Baryshnikov performed together at the New York State Theater for Cunningham's 80th birthday.
