What year did Helen Keller became a teacher?

Helen Keller did not become a teacher in the traditional sense. She was a writer, lecturer, and activist who spoke about her experiences with disability and advocated for the rights of people with disabilities.

While she never held a formal teaching position, she inspired countless people through her writings and public speaking. Her autobiography, "The Story of My Life," is still a powerful testament to the human spirit and the importance of education and inclusion.
