A Franciscan friar who is widely regarded as the father of modern accounting. While he did not invent double-entry bookkeeping, he was the first to write a treatise on it. He was also the first to describe balance sheets and income statements. He famously said, "A person should not go to sleep at night until the debits equal the credits." He died in 1517.
