In the early twentieth century, Arthur Young and Alwin C. Ernst founded two of the world’s most influential accounting firms. Ernst established Ernst & Ernst in 1903, while Arthur Young founded Arthur Young & Co. in 1906. Their firms would later merge in 1989 to form Ernst & Young (EY). This period exemplifies 20th century accounting: rapid industrialization, growing corporates, and the need for reliable audits, tax services, and financial controls. The 20th century accounting landscape saw the rise of securities regulation, income taxation, and global capital markets, all of which propelled the development of accounting standards and the accounting profession’s role in governance.
Both pioneers recognized that businesses needed more than financial reporting and auditing. They expanded professional services to include tax advice, business consulting, and financial management, helping organizations navigate increasingly complex commercial and regulatory environments. Their approach transformed the accounting profession by demonstrating that accountants could act as trusted business advisers as well as independent auditors. As tax legislation and corporate regulation evolved, firms like Ernst & Ernst and Arthur Young & Co. played an important role in developing structured tax planning, compliance services, and strategic financial advice. This evolution is central to the development of accounting because it broadened the scope from ledger-centric bookkeeping to holistic financial stewardship.
Key milestones in the history of accounting include ancient record-keeping systems, the emergence of double-entry bookkeeping, the 19th century rise of professional institutes, leading up to the establishment of auditing norms and financial reporting during 20th century and today's globalization and digitization of the accounting profession. Each milestone corresponds to broader economic and technological changes. For example, 20th century accounting incorporated standardized financial statements, external auditing, and tax compliance in response to securities laws and expanding multinational operations. In turn, the accounting profession adopted stricter ethics, independence rules, and continuing education.
Today, the principles established by early innovators and firms like Ernst & Young continue to shape modern accounting, corporate tax advisory, audit, and consulting services across the globe. The field of accounting now encompasses sustainability reporting, data analytics, and real-time assurance, while the history of accounting reminds us that the field advances when new risks, regulations, and technologies demand better information. In summary, the development of accounting depends the progressive refinement of methods and roles by figures such as Ernst & Young.
