Amatino Manucci

Amatino Manucci gave us the earliest extant accounting of double-entry bookkeeping. Manucci kept the accounts for Giovanni Farolfi & Company, a merchant partnership based in Nîmes, France. The writing, entirely in Manucci’s hand, is neat, legible, and mostly well preserved. Financial records from 1299—1300 survive that he kept for the firm's branch in Salon, Provence. Although these records are incomplete, they show enough detail to be identified as double-entry bookkeeping. These details include the use of debits and credits and duality of entries. "No more is known of Amatino Manucci than this ledger that he kept."
