The profession of occupational therapy emerged in North America and northern Europe at the beginning of the twentieth century. The first professional occupational therapy association was founded in the USA in 1917 (Paterson 2010); the Canadian Association of Occupational Therapists in 1926 (Friedland 2011) and the Scottish Association of Occupational Therapy in 1932 (Paterson 2010). A meeting to establish an international association was held in England in 1952, when the World Federation of Occupational Therapists was inaugurated. The founder members of the new international body were: Australia, Canada, Denmark, India, Israel, New Zealand, South Africa, Sweden, the United Kingdom and the United States of America. Seven of these founding countries were Anglophone. The first president of the Federation was Scottish (Paterson 2010).
At the time when occupational therapy was emerging as a profession, the UK still had the remnants of an Empire that once stretched all around the world, and the USA also had influence across the globe. It was inevitable that the international language of the new profession of occupational therapy would be English.
