Who is the speaker?

Now it’s my turn to give the weekly oral report, and the topic Professor Smith has assigned me is the life of the poet Emily Dickenson. Compared with Walt Whitman, whom we discussed last week, I found Emily Dickenson strikingly different. She seems to be the complete opposite of Walt Whitman in her life and in her work. I would like to share briefly with the class some of the essential facts of her biography.
    Emily Dickenson was born in 1830 in Amherst, Massachusetts, a decade after Whitman. In her early 20th, for reasons which still remain a mystery, she began to withdraw from her ordinary contact with the world. For the remaining thirty years of her life, she was seldom seen outside her home. In this respect, she was quite unlike Whitman, who loved the great outdoors.
    Emily Dickenson spent her solitary days corresponding with her friends and writing hundreds of remarkable poems, notably, "I heard a fly buzz", and the poem we read for today "I am nobody".
    Although she showed some of her poems to her family, and sent some of her letters to her friends, only four were published in her lifetime. Most of them, almost twelve hundred poems, were discovered in her room after she died in 1886 at the age of 56. These poems have established her as a major poet, and several modern critics consider her the greatest woman poet in the England language.
    Er, that’s about all I have. Are there any questions? If not, we should probably begin talking about Dickenson’s poem "I am nobody".
