Finley Peter Dunne (July 10, 1867 — April 24, 1936) was an American humorist and writer from Chicago. He published "Mr. Dooley in Peace and War". The fictional Mr. Dooley expounded upon political and social issues of the day from his South Side Chicago Irish pub and he spoke with the thick verbiage and accent of an Irish immigrant from County Roscommon. Dunne's sly humor and political acumen won the support of President Theodore Roosevelt, a frequent target of Mr. Dooley's barbs. Indeed Dunne's sketches became so popular and such a litmus test of public opinion that they were read each week at White House cabinet meetings. n 1899, under the title Mr Dooley in Peace and War, a collection of the pieces was brought out in book form, received rave reviews from the critics, and was on the best seller list for a year. Dunne, then 32, became a national literary figure. (Excerpt from Wikipedia)
