The Miracle Worker is a cycle of 20th century dramatic works derived from Helen Keller's autobiography The Story of My Life. Each of the various dramas describes the relationship between Helen, a deafblind and initially almost feral child, and Anne Sullivan, the teacher who introduced her to education, activism, and international stardom. Its first realization was a 1957 Playhouse 90 broadcast written by William Gibson and starring Teresa Wright as Sullivan and Patricia McCormack as Keller. Gibson adapted his teleplay for a 1959 Broadway production with Anne Bancroft as Sullivan. The first movie, also starring Bancroft, was released in 1962. Subsequent made-for-television movies were released in 1979 and 2000.
The title originates in Mark Twain's description of Sullivan as a "miracle worker". The famed American humorist and author was an admirer of both women, and although his own personal finances were problematic, he helped arrange the funding of Keller's Radcliffe College education by his friend, financier and industrialist Henry Huttleston Rogers.
