Harry Sinclair Lewis (February 7, 1885 – January 10, 1951), better known as Sinclair Lewis, was an American novelist, short-story writer, and playwright. In 1930, he became the first writer from the United States to receive the Nobel Prize in Literature, which was awarded “for his vigorous and graphic art of description and his ability to create, with wit and humor, new types of characters.” His works are known for their insightful and critical views of American capitalism and materialism between the wars. He is also respected for his strong characterizations of modern working women. Source Wikipedia
