BDO's roots go as far back as 1910 when the USA founding firm, Seidman and Seidman was founded. At this stage there were only 2 000 certified public accountants practicing in the USA. The forerunner to BDO in South Africa, Charles Welby Steward was started in Cape Town in 1916. In 1938, Jock Spencer and Bill Shaw formed Spencer Shaw Hood & Co in South Africa. Bob Hood joined last and the name changed to Spencer Shaw Hood & Co. In 1963 an agreement was reached between Johannesburg firm Spencer Shaw Hood, Cape Town firm Welby Steward, and Durban firm Arthur Hopewell to use the same name (Spencer Shaw Hood), logo and audit methodology. This firm merged with Ross Spencer Rule in 1976, and Spencer Steward & Co was formed. It joined the BDO network in 1980 and grew in size when Dreyer & Dreyer joined in 1984, Ironsides in 1986 and Henry & Storey in 1987. In 1988 the firm became known as BDO Spencer Steward. The tax practice was bolstered in 2001 when specialist tax firm Munnik Fourie joined. 2010 saw a repositioning of the brand internationally, when all local member firm names were dropped. This ensured that BDO positioned itself as a truly global network with one name. Moore Stephens' Johannesburg office joined BDO in 2010, as did Cameron Prentice in Cape Town. BDO merged with RW Irish in Johannesburg in 2015.
