(1867–1940), American freelance journalist and writer. Born in Ridgway, Pennsylvania, Mayo grew up in Boston and lived in Dutch Guiana with her father from 1899 to 1907. Two years later, she began a lifelong friendship with Moyca Newell, a wealthy heiress. Newell financed Mayo and collaborated with her on several projects, the best known being a successful campaign to initiate a state police department in New York. Mayo settled in Bedford Hills, New York, traveling extensively and making a reputation by writing books and magazine articles on a variety of subjects, including mismanagement in the YMCA, exclusion of Asians from immigration to the United States, and the unsanitary practices of Filipinos.
