Price Waterhouse was a UK firm which opened a US office in 1890, and later established a separate US partnership. The UK and US Peat Marwick Mitchell firms adopted a common name in 1925. Other firms used separate names for domestic business, and did not adopt common names until much later. For instance, Touche Ross was named such in 1960, Arthur Young, McLelland, Moores & Co in 1968, Coopers & Lybrand in 1973, Deloitte Haskins & Sells in 1978 and Ernst & Whinney in 1979. Even now, Deloitte's technical name is Deloitte Touche Tohmatsu Limited, which reflects its history of mergers.
