William Newton Dunn [commonly known as William Dunn] was born in 1859 and was articled to Duncan McNaughtan (1845-1912) in Glasgow, in 1876. Having qualified as an architect, he moved to London where he established an independent practice in 1889.
In 1890 Dunn and the Edinburgh architect Robert Watson (1865-1916) formed a partnership, Dunn & Watson, to continue the London practice of James Marjoribanks MacLaren (1853-1890) who had died that year. Over the next 22 years the practice worked on commissions in many parts of England, and in Scotland, South Africa and Romania
In 1912 William Curtis Green (1875-1960) joined the practice which was renamed Dunn, Watson & Curtis Green. Following the death of Watson in 1916 the practice became Dunn & Curtis Green. This partnership was dissolved in 1919 when Dunn retired to Kenya, where he died on 7 February 1934.
