Helen Adams Keller (June 27, 1880 â June 1, 1968) was an American author, political activist, and lecturer.
Helen Keller's First Words. On April 5, 1887, less than a month after her arrival in Tuscumbia, Anne sought to resolve the confusion her pupil was having between the nouns mug and milk, which Helen confused with the verb drink.. Anne took Helen to the water pump outside and put Helen's hand under the spout. As the cool water gushed over one hand, she spelled into the other hand the word w-a-t-e-r first slowly, then rapidly. Suddenly, the signals had meaning in Helen's mind.
