About us

A timeline of our history

More than a century of exceeding high expectations

For more than 100 years, clients have relied on Deloitte LLP and its predecessor organizations for solutions to their ever-changing needs. We are a national and global leader today because we have sustained our clients’ trust and exceeded their expectations throughout our history.

Great leaders, such as William Welch Deloitte, George A. Touche, Charles Haskins and Elijah Watt Sells helped define and expand the foundations of our profession and the value of our service. As we embark upon our second century of achievement, the story of our forebears and the outstanding clients they served continues to motivate and inspire us. These great clients, great leaders and great moments shaped the culture of client service that distinguishes the organization today.

Beginnings: The roots of the profession

Haskins, Sells and the Dockery Commission

In 1893, with the United States in an economic decline, government inefficiency became a target of public concern. Representative A. M. Dockery (R-MO) appointed two accountants to investigate: Charles Haskins and Elijah Watt Sells. During the next two years, Sells and Haskins transformed how the US government did business. Department by department, they found ways to simplify work and increase efficiency. Altogether, their recommendations saved the government $600,000 a year while improving work quality. On March 4, 1895, the two opened offices in New York City offering accounting services to the public. In time, Haskins & Sells opened successful offices in Chicago and London and helped lead a young profession to maturity.

Deloitte, Touche and the development of modern accounting

In England, the Industrial Revolution spawned a new type of enterprise that raised capital by selling equity to the public. The Great Western Railway (GWR) was one of the most famous of these early "joint stock companies." When its stock price slumped in 1849, GWR turned to an independent public accountant, William Welch Deloitte, to audit the company. The experience was so valuable that GWR directors recommended compulsory independent oversight. This recommendation was gradually implemented in England, but 84 years passed before the United States adopted the practice. The boom in joint stock companies created demand for people skilled at understanding and solving complex business problems. George A. Touche, a Scotsman, established a London-based accounting company in 1898 to help meet that demand. Two years later, he followed the flow of British capital to the United States, establishing the first US office of Touche, Niven & Company.


1900 – 1930

The new era of the income tax

John Ballantine Niven established the offices of Touche Niven alongside Haskins & Sells in the Johnston Building at 30 Broad Street in 1900 in New York. At the time, fewer than 500 CPAs practiced in the United States. But a new area of accounting was soon to generate enormous demand for accounting professionals—the era of the income tax.

In 1913, Niven opened the organization's first branch offices in Minneapolis and Chicago. That same year, the 16th Amendment to the Constitution allowed income tax to be levied on Americans for the first time. Compared with modern levels, the 1913 rate of 1 percent on taxable incomes over $3,000, rising to 7 percent on taxable incomes over $500,000, may seem low. But, as the Journal of Accountancy noted that year, it was "indubitable that the income tax law is to have a more far-reaching effect upon public accountants than upon any other profession or business in the country.

"Hundreds of men who have never seen the necessity for a correct system of accounting," the Journal continued, "now find themselves compelled to prepare statements of income and expenditure; and the work in nine cases out of ten will fall upon the shoulders of the public accountants of the several states." The Journal was so convinced of the demands of the new legislation that it added a tax column—and asked Niven to be the editor. Under his direction, the column advised accountants of the requirements of income tax, preparing the profession for the impact of World War I, when federal spending rose from $742 million in 1916 to $18.9 billion in 1919. By then, income tax provided 58 percent of federal revenues, and the experts who handled income taxes found their skills in great demand.

After the crash: Audits and regulations

“Free, fair and full reports of industrial organizations,” the January 12, 1901, issue of Commerce, Accounts & Finance said, “ should be founded upon thorough, independent audits of accounts by disinterested certified public accountants, whose signed certificates, to be published with the report, are a more nearly perfect guarantee of reliability than any other yet to be discovered.”

The article, believed to have been written by Charles Haskins, was one of many calls for independent auditing in the early decades of the century. But these calls were largely ignored by Washington and Wall Street regulators. The stock market crash of 1929 and the ensuing Depression brought the issue into the public spotlight, especially when it became obvious that proper accounting practices might have prevented some bankruptcies and consequent unemployment.

On April 1, 1933, Colonel Arthur Carter, President of the New York State Society of CPAs, testified before the US Senate Committee on Banking and Currency. As the only accountant to testify, Carter helped convince Congress that independent audits should be mandatory for public corporations. The 1933 Securities Act subsequently required public corporations to file independently certified registration statements and periodic reports. A year later, the Securities and Exchange Commission was created to administer the new legislation.

The regulating bodies immediately needed accountants. Women accountants, who (except for the remarkable Jennie Palen) had been unable to make headway at the leading firms, suddenly found themselves in demand.

Postwar growth

After World War II, America stood on the brink of historic economic expansion. In this environment, in 1947, Detroit accountant George Bailey, then president of the AICPA, launched his own organization. The new entity enjoyed such a positive start that in less than a year, the partners merged with Touche Niven and A.R. Smart to form Touche, Niven, Bailey & Smart. Headed by Bailey, the organization grew rapidly, in part by creating a dedicated Management Consulting (MC) function. It also forged closer links with organizations established by the cofounder of Touche Niven, George Touche: the Canadian organization Ross, Touche and the British organization George A. Touche. In 1960, the organization was renamed Touche, Ross, Bailey & Smart, becoming Touche Ross in 1969. John William Queenan joined Haskins & Sells in 1936. As managing partner from 1956 until his retirement in 1970, he led the organization through major developments in the profession. Haskins & Sells experienced its own major development by merging with 26 domestic organizations and establishing offices in Canada, Central and South America, Europe, and Japan.

Leading the information revolution

In the 1950s, information technologies became increasingly important in business. Few professions were affected more than accounting. Data processing machines freed accountants to focus on developing and monitoring systems to improve the way clients managed. Characteristically, Touche Ross led the profession into this uncharted territory. In 1952, it became the first large accounting organization to automate its bookkeeping. Later, Gordon Stubbs wrote Data Processing by Electronics and Introduction to Data Processing, the first two professional brochures of their kind. In 1964, the organization's work with statistical sampling led to the Auditape System, which brought computer technology to audits. The organization's MC group, which provided computer systems advice, felt the greatest impact from the technology revolution. The organization did pioneering work for several leading corporations and for many government agencies. At Touche Ross, the discipline matured during the 1960s and 1970s under the direction of leaders like Robert Trueblood and Michael Chetkovich.

1970 – 1990

The 1980s: A new style of management

In the 1980s, Deloitte & Touche led the profession through a decade of unprecedented merger and acquisition activity in American business. At the close of the decade, Emerson’s Professional Services Review commented, “When it comes to acquisition services, no one rivals the Deloitte & Touche infrastructure, commitment, expertise or reputation.

The organization's proficiency in mergers and acquisitions emerged in the 1970s when a new style of management became prominent in corporate America. The new managers were financially sophisticated and aware of the synergies and economies of scale offered by mergers and acquisitions. They relied on their accountants for more than audit and tax skills, and looked for insightful advice, technological expertise, global operations and support for their merger and acquisition activity.

Without sacrificing technical audit proficiency or ethical standards, managing partners Russell Palmer and Charles Steele led the way into this new world of business. Accountants began to emphasize their abilities as business consultants—offering the full range of accounting services and actively seeking additional ways to help their clients.

A new generation of leaders rose to the top of Touche Ross and Deloitte Haskins Sells during these years. In 1982, the two-man team of David Moxley and W. Grant Gregory succeeded Russell Palmer as leaders of Touche Ross. In 1985, Edward A. Kangas, who had made his name in management consulting, was appointed managing partner of Touche Ross. In 1984, J. Michael Cook became managing partner of Deloitte Haskins Sells.

As the rate of mergers and acquisitions accelerated, corporate America became increasingly globalized. Corporations increasingly sought advisers skilled in all areas of accounting and proficient at solving problems throughout the world. Many turned to Deloitte & Touche for just such assistance. To cap off this decade of merger and acquisition activity, Touche Ross and Deloitte Haskins Sells merged in 1989.

The newly formed Deloitte & Touche was led by J. Michael Cook and Edward A. Kangas, who shared the belief that successful accountants of the future would combine strong professional abilities with a deep understanding of their clients’ industries, situations and needs.

Competing for the future

The information revolution and globalization offered the organization larger and more diverse challenges. With the dismantling of the Berlin Wall, the emergence of trading regions such as the European Economic Community, the growing economic power of the Pacific Rim and the growth in cross-border trade through agreements such as NAFTA, the organization's clients demanded increasingly integrated cross-border solutions.

Deloitte & Touche set out to provide the coordinated, global services and solutions our clients required. To do so, the organization needed more than technological sophistication and a knowledge of international business. It needed, as managing partner James E. Copeland, Jr., pointed out in 1994, the intellectual equivalent of systems integration—the ability to combine competencies from all functional disciplines across national borders to create solutions for clients.

To achieve our goals, we had to hire high-caliber recruits in every country, then train them to excel. We had to maintain the highest ethical standards in the world. We had to be, in the words of the firm’s powerful mission statement, “the professional services firm that consistently exceeds the expectations of our clients and our people.”

In 1995, a century after its founding, the partners of Deloitte & Touche voted to create Deloitte Consulting to better serve our multinational clients. While the specifics of the world of business have changed in the past 100 years, the overall commitments and goals of the organization remain the same as the day Haskins and Sells shook hands on their partnership, and Touche sent Niven to open an office in New York. As Haskins noted more than 100 years ago, our “study and interest is the soundness of the world of affairs.” Our goal continues to be to “simplify work so that it can be done more rapidly and more effectively.”
