Work and InfluenceIn 1936, Keller's beloved teacher and devoted companion, Anne Sullivan, died. She had experienced health problems for several years and, in 1932, lost her eyesight completely. A young woman named Polly Thompson, who had begun working as a secretary for Keller and Sullivan in 1914, became Keller's constant companion upon Sullivan's death.
In 1946, Keller was appointed counselor of international relations for the American Foundation of Overseas Blind. Between 1946 and 1957, she traveled to 35 countries on five continents. In 1955, at age 75, Keller embarked on the longest and most grueling trip of her life: a 40,000-mile, five-month trek across Asia. Through her many speeches and appearances, she brought inspiration and encouragement to millions of people.
Keller's autobiography, The Story of My Life, was used as the basis for 1957 television drama The Miracle Worker. In 1959, the story was developed into a Broadway play of the same title, starring Patty Duke as Keller and Anne Bancroft as Sullivan. The two actresses also performed those roles in the 1962 award-winning film version of the play.
Death and LegacyKeller suffered a series of strokes in 1961, and spent the remaining years of her life at her home in Connecticut. During her lifetime, she received many honors in recognition of her accomplishments, including the Theodore Roosevelt Distinguished Service Medal in 1936, the Presidential Medal of Freedom in 1964, and election to the Women's Hall of Fame in 1965. She also received honorary doctoral degrees from Temple University and Harvard University and from the universities of Glasgow, Scotland; Berlin, Germany; Delhi, India; and Witwatersrand in Johannesburg, South Africa. Additionally, she was named an Honorary Fellow of the Educational Institute of Scotland.
Keller died in her sleep on June 1, 1968, just a few weeks before her 88th birthday. During her remarkable life, Keller stood as a powerful example of how determination, hard work, and imagination can allow an individual to triumph over adversity. By overcoming difficult conditions with a great deal of persistence, she grew into a respected and world-renowned activist who labored for the betterment of others.
