The identity of English highwayman Dick Turpin was uncovered by his former schoolmate, who recognised his handwriting, leading to Turpin's trial.
Highwayman
A highwayman was a robber who stole from travellers. This type of thief usually travelled and robbed by horse as compared to a footpad who travelled and robbed on foot; mounted highwaymen were widely considered to be socially superior to footpads. Such criminals operated until the mid- or late 19th century. Highwaywomen, such as Katherine Ferrers, were said to also exist, often dressing as men, especially in fiction.
Dick Turpin
Richard Turpin was an English highwayman whose exploits were romanticised following his execution in York for horse theft. Turpin may have followed his father's trade as a butcher early in his life but, by the early 1730s, he had joined a gang of deer thieves and, later, became a poacher, burglar, horse thief, and killer. He is also known for a fictional 200-mile (320 km) overnight ride from London to York on his horse Black Bess, a story that was made famous by the Victorian novelist William Harrison Ainsworth almost 100 years after Turpin's death.
Handwriting
Handwriting is the personal and unique style of writing with a writing instrument, such as a pen or pencil in the hand. Handwriting includes both block and cursive styles and is separate from generic and formal handwriting script/style, calligraphy or typeface. Because each person's handwriting is unique and different, it can be used to verify a document's writer. The deterioration of a person's handwriting is also a symptom or result of several different diseases. The inability to produce clear and coherent handwriting is also known as dysgraphia.
