Deloitte Touche Tohmatsu Limited, commonly referred to as Deloitte, is one of the world's Big Four professional services firms along with PricewaterhouseCoopers (PwC), Ernst & Young and KPMG. It is the largest professional services network in the world by revenue and has 193,000 employees in more than 150 countries providing audit, tax, consulting, enterprise risk and financial advisory services.
The multi-national corporation traces its roots to a pair of accounting firms established first in London, then opening offices in the United States. In 1845, William Welch Deloitte opened an office on Basinghall Street in London. Meanwhile, in 1896 Charles Waldo Haskins and Elijah Watt Sells formed Haskins & Sells in New York. It was later described as "the first major auditing firm in the country to be established by American rather than British accountants." The eventual merger of these two companies became Deloitte, Haskins and Sells.
Similarly, in 1898, George Touche established an office in London and then in 1900 joined John Ballantine Niven in establishing the firm of Touche Niven in New York. Touche Nevin grew rapidly, in part by creating a dedicated management consulting function. It also forged closer links with earliest organizations established by co-founder George Touche, the Canadian organization Ross and the British organization George A. Touche.
In 1968, Nobuzo Tohmatsu formed Tohmatsu Aoki & Co, a firm based in Japan that became part of the Touche Ross network in 1975.
In 1989, Deloitte Haskins & Sells (USA) merged with Touche Ross (USA) to form Deloitte & Touche. The international firm was renamed Deloitte Touche Tohmatsu, in 1993 to reflect the contribution from the Japanese firm.
Partners of Deloitte & Touche created Deloitte & Touche Consulting Group, now known as Deloitte Consulting in 1995.
In 2008, Deloitte adopted its new Always One Step Ahead tag line to support its corporate vision - To be the Standard of Excellence.
