The idea that handwriting reveals character appears in classical antiquity — both Aristotle and Suetonius made observations connecting writing style to personality. The formal study of graphology, however, began in 17th-century France with Camillo Baldi's Trattato come da una lettera missiva si conoscano la natura e qualità dello scrittore (1622) — the first systematic text on handwriting analysis.
The 19th century saw graphology develop rapidly in France (the Abbé Michon coined the term "graphologie" in 1871 and founded the first graphology school) and Germany (Ludwig Klages developed a more philosophically sophisticated system that dominated German graphology throughout the 20th century). By the early 20th century, graphology was being used for personnel selection in France, Germany and Switzerland — a practice that continues in parts of Europe to this day.
In the English-speaking world, graphology has always been more marginal — treated with greater scepticism and less integrated into mainstream practice. This partly reflects the genuinely mixed scientific evidence and partly reflects cultural differences in the relationship between intuitive and analytical approaches to assessment.
