What was the contribution of hellen' s parents in her education?(150words)

When Helen was six, her mother contacted Dr. Alexander Graham Bell (1847–1922), whom she had heard was working on devices to help the deaf. Bell met with Helen and her parents and suggested that they contact the Perkins Institute for the Blind in Boston, Massachusetts. In March 1887 Anne Sullivan (1866–1936), a teacher at the institute, came to serve as Helen's teacher. Anne was twenty-one years old and had sight limitations of her own. One month after her arrival, Sullivan had taught Keller the word "water." She did this by using her fingers to spell letters into Helen's hand. From this she understood that objects had names, and that her teacher spelled these names into her hand. Hence her parents unlocked a whole new world of learning for Helen.
