Born in Ireland, John Brougham originally pursued a surgical career at the Peter Street Hospital in Dublin. A change in fortune resulted in his decision to move to England and become an actor in 1830. He was associated with London's Tottenham Street Theatre, the Olympic Theatre, and became manager of the London Lyceum in 1840. Brougham produced over 100 works and is remembered for his comedic playwriting and acting.
Though much of her early life, including her real name and exact date of birth, remains in shadow, Laura Keene is thought to have come from a well-to-do background. She was widely read and spent time in Turner’s studio during her childhood. After performing with Madame Vestris’ company, Keene journeyed to New York in 1852 at the invitation of James W. Wallack. She became the leading lady of his theater and enjoyed great success.
Maurice and Max Strakosch were brothers who emigrated from Austria. Their connection to the Pfaff's circle is tenuous; only two known sources tie them to Pfaff's directly. Furthermore, the sources indicate that contemporaries may have confused Maurice and Max with one another.
Wallack’s Lyceum was located in Broadway near Broome Street. Its productions included original works by Pfaffians John Brougham, Stephen Ryder Fiske, and Fitz-James O’Brien. The Lyceum, run by James W. Wallack, was at one time the leading theater in New York City.
