Mary Williams (June 27, 1869 - February 11, 1961), who wrote pseudonymously as Kate Carew, was a caricaturist self-styled as "The Only Woman Caricaturist". She worked at the New York World from 1890 to 1901, providing illustrated celebrity interviews.
Williams was born in Oakland, California, and attended the San Francisco School of Art and Design. She worked as a staff artist for the San Francisco Examiner in the 1890s, under the sponsorship of Ambrose Bierce. She moved to New York City, when she fell in love with Harry Kellett Chambers, an Australian journalist and playwright. There she worked for several New York dailies; Joseph Pulitzer hired her to work for his "New York World" newspaper doing illustrated celebrity interviews. She was sent to London and Paris, where she interviewed Picasso and Rostand, John Galsworthy, George Moore, Bret Harte (who happened to be in England at the time), and many others. She wrote about 500 pieces for New York City newspapers and later for the London Tatler, The Patrician and Eve.
Williams settled in England circa 1912, when her husband left her for Maria Cristina Mena, a young Mexican writer. Her career as a caricaturist ended circa 1920 when she developed what may have been carpal tunnel syndrome, and could no longer do fine work. She by then had married her third husband, and lived in Europe, painting, until World War I, when she moved back to California. She died in Monterey, California, and is buried in Oakland.
