Helping clients unlock their potential for growth has been deeply embedded in Grant Thornton’s DNA for more than 100 years.

The global organisation we recognise today dates back to 1904, when Thornton & Thornton was formed in Oxford, UK. Twenty years later and on the other side of the Atlantic, 26-year-old senior accountant Alexander Richardson Grant established Alexander Grant & Co in Chicago, US.

Supporting dynamic organisations has been high on our agenda from the beginning. Thornton & Thornton advised automotive pioneer Morris Motors on its flotation in 1936 and also delivered international audit services before the Second World War.
