On 29 November 1820, Kean appeared for the first time in New York City as Richard III. The success of his visit to America was unmistakable, although he fell into a annoying dispute with the news media. In 1821, Kean appeared in Boston with Mary Ann Duff in "The Distrest Mother", by Ambrose Philips, an adaptation of Racine's Andromaque. On 4 June 1821, he returned to England.
