Edwin Lefèvre (1871-1943) was an American journalist, writer, and diplomat who is most noted for his writings about Wall Street, most notably Reminiscences of a Stock Operator (1923). He began his career as a journalist and eventually became a stockbroker as well. Edwin Lefèvre's first short stories were published under the title, Wall Street Stories (1901), which were followed by several novels about money and finance. Lefèvre was appointed an Ambassador of the United States by President Howard Taft in 1909, serving in posts in Italy, France, and Spain. In 1913, Lefévre returned to his home in Vermont where he resumed writing novels and contributing short stories for magazines such as The Saturday Evening Post and McClure's.
