**Una O'Connor (1880-1959)** was an Irish actress, renowned for her prolific film career as a character actress in Hollywood.

Known for her high-pitched voice and nervous, often hysterical expressions, she typically portrayed maids, landladies, gossipy neighbors, or anxious and comedic figures. Her style was immediately recognizable and often provided comic relief.

She left an indelible mark on numerous classics. Her most memorable roles include Minnie, the screaming maid in *Bride of Frankenstein* (1935), and Mrs. Hall, the innkeeper in *The Invisible Man* (1933). She also appeared in *The Adventures of Robin Hood* (1938) and, in one of her last performances, in *Witness for the Prosecution* (1957).
