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.
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").
