The Mallory brothers and Mackaye soon fell out, and Mackaye lost the rights to his single commercially successful play, Hazel Kirke, and his position at the theatre. By then Business Manager Daniel Frohman had hired his brothers Gustave and Charles. They used Hazel Kirke's long run to implement the nation's first theatrical touring organization with multiple companies of a single play and developed their promotional and management skills. The Frohmans, along with Marcus Klaw and Abraham Lincoln Erlanger, who met while working in the Madison Square Theatre's publicity department, and David Belasco, who also worked at the theatre in this period, became major forces in American theatrical management over the next 35 years.
