Helen Keller was born on June 27, 1880 in Tuscumbia, Alabama to Captain Arthur and Kate Keller. Helen was healthy until the age of nineteen months when she developed a brain fever that may have been scarlet fever. The fever left her unable to hear, see or speak. Captain Keller was a newspaper editor and was determined to find help for his child. He contacted Dr. Alexander Graham Bell to assist him. Dr. Bell found Michael Anagnos, the director of the Perkins Institution for the blind in Boston, Massachusetts. Mr. Anagnos sent one of his best students, Annie Sullivan to help Helen. The students at the Perkins Institution made a doll for Annie Sullivan to give Helen. Ms. Sullivan began using the doll to spell the word doll in Helen's hand. Helen learned quickly to make the letters. Helen learned many words and soon wanted to learn to speak. Miss Sarah Fuller of the Horace Mann School was her first speech teacher. Helen learned to use the raised print for reading and soon wanted to go on to college. Helen graduated from Radcliffe College with honors in 1904. Annie Sullivan spelled books and lectures in Helen's hand all through college. Helen Keller spent the rest of her life trying to make it easier for disabled people to learn. She fought for women's rights, equality for minorities and worker's rights. She was a crusader for people who needed help. Helen Keller won many awards for her work for the blind. Helen Keller died on June 1, 1968, a few weeks short of her 88th birthday. She will be remembered by the world as a champion and hero of the blind and disabled people. Which of the following is true?
