Firm's history

William Deloitte, was the Grandson of Count de Loitte who fled from France to England during the French Revolution. He started his career in 1844 at the age of 15 and became one of the fathers of the accountancy profession. He learned the business at the Bankruptcy Court in London. When he opened his own office he made his name with the industry of the day -the railways. He discovered frauds and invented a system for railway accounts which protected investors from mismanagement of funds. In 1893 he opened offices in the US.

When George Touche became an accountant in 1883 there was no 'e' on the end of his name. It was pronounced in the Scottish way of Toch. However by 1906, with a view to preventing the mispronunciation of his surname, he had changed it to Touche. Financial disasters in the new and booming investment trust business gave him his business opportunity. His flair for saving doomed businesses from disaster also enhanced his reputation. Touche became was knighted in 1917. He died in 1935.

The Japanese firm of Tohmatsu owes its origins to Admiral Nobuzo Tohmatsu. At the Naval Paymasters' Academy he taught Iwao Tomita who, after the war, established an office in Tokyo. In 1968 he joined with his old mentor, Tohmatsu, and they founded Tohmatsu in order to assist the Japanese Government founding national audit corporations. The key to Tohmatsu's growth was to become internationally focused. They sent a substantial number of partners overseas to gain experience, which resulted in long-standing worldwide clients who are still with the practice today.
