Pauline Wayne was a Holstein cow which belonged to William Howard Taft, the 27th President of the United States. Also known as "Miss Wayne", Pauline was not Taft's first presidential cow: she replaced the lesser-known "Mooley Wooly", who provided milk for the First Family for a year and a half. Taft and his wife, Helen Herron Taft, had growing children, and Taft was a notoriously large eater. Accordingly, Mooley Wooly was replaced by Pauline Wayne, because the former could not produce enough milk for the Taft's growing family. Wisconsin senator Isaac Stephenson bought Pauline Wayne for Mrs. Taft.
