So far, modern accounting can not be separated from double-entry bookkeeping, and double-entry bookkeeping can not be separated from luca pacioli. Anyone with a little knowledge of accounting history knows that luca pacioli's name is closely related to double-entry bookkeeping and modern accounting based on double-entry bookkeeping. Whether luca pacioli's "Accounting Theory" is the first book describing double-entry bookkeeping may still be controversial, but whatever its conclusion, it will not damage luca pacioli's position in the history of accounting development and its great and far-reaching influence. Luca pacioli is a well-deserved "father of modern accounting".
