Charles Dickens used the pseudonym "Boz" when he first published a series of original descriptive sketches of daily life in London.

He adopted this name from his younger brother, who was nicknamed "Boz." These sketches, published in the *Morning Chronicle* and later collected as *Sketches by Boz*, were a stepping stone to his later literary success.
