Early history[edit]

In 1924, 26-year-old Alexander Richardson Grant founded Alexander Grant & Co. in Chicago. Grant had been a senior accountant with Ernst & Ernst (now EY). Alexander Grant was committed to providing services to mid-sized companies.

When Grant died in 1938, Alexander Grant & Co. survived the change in leadership and continued to grow nationally. In 1969, Alexander Grant & Co. joined with firms from Australia, Canada, and the United States to establish the organization of Alexander Grant Tansley Witt. This organization operated successfully for 10 years.

By 1980, Alexander Grant & Co. joined with 49 other accounting firms, including Thornton Baker in the UK, a firm with similar qualities, clients, personnel numbers and values, to form a global organization, Grant Thornton. In 1986, Alexander Grant & Co. changed its name to Grant Thornton, reflecting its affiliation with the United Kingdom firm Thornton Baker, which also changed its name to Grant Thornton.[2]

Recent awards[edit]

Network of the year 2013: Grant Thornton was named International Accounting Bulletin’s ‘Network of the year’. The IAB is the only magazine to cover the global accounting profession[3]

Universum Top 50 world’s most attractive employer: More than 200,000 students named Grant Thornton one of the top 50 most attractive global employers.[4]

Recent significant mergers[edit]

  • Grant Thornton UK merged with RSM Robson Rhodes in July 2007[5]
  • Grant Thornton China merged with Ascenda CPA in January 2012[6]
  • In May 2012 Grant Thornton Australia merged with several former BDO offices in Melbourne and Sydney.
  • In July 2013, Grant Thorton Johannesburg merged with the local PKF member firm.[7]

Although many of the firms now carry the Grant Thornton international name, they are not all members of one international partnership. Each member firm[8] is a separate national entity, and governs itself and manages its administrative matters independently on a local basis. This is similar to other professional services networks.
