Jeremy Diddler
Jeremy Diddler is a fictional character in James Kenney's 1803 farce Raising the Wind, based on an amusing importunist named Bibb, or “half-crown Bibb”.
A needy artful swindler, Diddler became a stock character in farce; the word “diddle” may be derived from him, or vice versa, and was a very common expression in the 19th and early 20th centuries.
Diddler is discussed in some detail in Herman Melville's The Confidence Man: His Masquerade. He appears in Thomas Haynes Bayly's novel David Dumps.
