How We Came to Be
Historians have traced the roots of internal auditing to centuries B.C., as merchants verified receipts for grain brought to market. The real growth of the profession occurred in the 19th and 20th centuries with the expansion of corporate business. Demand grew for systems of control in companies conducting operations in many locations and employing thousands of people. Many people associate the genesis of modern internal auditing with the establishment of The IIA.
The year 1941 marked a major turning point. Victor Z. Brink authored the first major book on internal auditing. And at the same time, John B. Thurston, internal auditor for the North American Company in New York, had been looking to establish an organization for internal auditors. He and Robert B. Milne had served together on an internal auditing subcommittee formed jointly by the Edison Electric Institute and the American Gas Association, and they agreed that bringing internal auditing to its proper level of recognition would best be achieved by forming an independent organization for internal auditors. When Thurston learned of Brink’s book, the three men got together and found they had a mutual interest in furthering the role of internal auditing.
Membership grew quickly. It went from the original 24 members to 104 by the end of the first year, to 1,018 at the end of five years. By 1957, membership had expanded to 3,700 and 20 percent were located outside of the United States. More than 70 years later, The IIA is a dynamic global organization with more than 245,000 members worldwide. How did this grow from 24 enthusiastic men in New York City to what it is today? It has required selfless volunteerism, dedicated professionals, and most of all, people with a desire to make internal auditing a proud and distinguished profession.
