Father of Accounting:
Franciscan friar, magician, and mathematician, Fra Luca Pacioli is often called “The Father of Accounting” as his Summa contains, among comprehensive mathematical knowledge of the time, the first published rules of double-entry bookkeeping. Tractatus XI defines accounting practices that still form the basis of the field, such as the use of ledgers to account for assets, liabilities, capital, income, and expenses.
Leonardo da Vinci was fascinated by the Summa’s explanation of the mathematics of perspective. Not long after the book’s publication, Pacioli taught, collaborated with, and lived with Leonardo in Milan, Italy.
In 2019, the complete Summa sold for $1.2 million. If you’d like to own one of the most sought-after and important pieces of accounting history without spending $1.2 million for the whole Summa, consider this lovely Tractatus XI priced at less than 2% of that figure.
