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.
Adah Menken, an actress "not known for her talent, but rather for her frenetic energy, her charismatic presence, and her willingness to expose herself," was born in a suburb of New Orleans (Richards 192). Adah’s given name was probably Adah Bertha Theodore, but conflicting accounts of her early years and parentage (many generated by herself for publicity purposes) make it difficult to say with certainty.
An "American dancer and adventuress," the woman later known as Lola Montez has several different birthdates, but scholar Bruce Seymour argues that she was likely born in 1820 in Ireland as Marie Dolores Eliza Rosanna Gilbert (Seymour 4). The thrice-married Gilbert first debuted in London as "Lola Montez" in 1843 and experienced success in Europe. In 1847, as the mistress of Louis I of Bavaria, Montez was made Baroness Rosenthal and Countess Lansfeld and was able to control the Bavarian government until she was opposed by the Jesuits and ousted by revolution in 1848 ("Montez").
Actor Edward Askew Sothern, who was known as Douglas Stewart in the early part of his career and possibly went by the initials E.A. Sothern in his later years, moved in theatrical circles like many of the Pfaffians, including playwright John Brougham, actress Adah Menken, and theater critic William Winter. Sothern was part of the troupe that theater historian George Odell describes as Laura Keene’s best company. In addition to working with Keene, he also appeared at Barnum’s and at Wallack’s during the 1854-55 season.
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.
