Herbert Henry Dunn (c. 1865–1935) was an English architect who worked in Lincoln in the early 20th century before becoming the surveyor to the Cambridgeshire County Council.
He designed buildings in Lincoln and Lincolnshire, before moving to Cambridgeshire shortly before the 1st World War.
[2] He then worked in the offices of W. Sindall builder in Cambridge from 1885 to 1887, and then as an improver and later assistant to William Cecil Marshall from 1887 to 1891.
[3] He shortly afterwards set up his own office at St Peter's Churchyard in Silver Street, Lincoln.
He was probably appointed Cambridgeshire county surveyor in 1910, after the death of William Milner Fawcett, who had previously held that position.
