Nellie Bly , pseudonym of Elizabeth Cochrane, also spelled Cochran (born May 5, 1864, Cochran’s Mills, Pennsylvania, U.S.—died January 27, 1922, New York, New York), American journalist whose around-the-world race against a fictional record brought her world renown.

Her exposé of conditions among the patients, published in the World and later collected in Ten Days in a Mad House (1887), precipitated a grand-jury investigation of the asylum and helped bring about needed improvements in patient care. Similar reportorial gambits took her into sweatshops, jails, and the legislature (where she exposed
