The Silent SpringIn 1958, Rachael Carson wrote to E.B. White, editor of The New Yorker magazine, to urge him to write a book. The environmental content she had in mind became her famous book, The Silent Spring. However, because White replied that although he felt unable to do it himself, he encouraged her to write it herself. So she did. |
