Educated at King's College London and the School of Mines, John Frederick Adolphus McNair was born in Bath on 23 October 1828 and began his career in the Madras Artillery. Over time, his work moved beyond military service into engineering and administration, especially in the Straits Settlements.
He became closely associated with Singapore's development in the later 19th century. Sources credit him with overseeing major building and infrastructure work, including projects linked to St Andrew's Cathedral, Government House, and other important public buildings. He was also involved in prison administration and wider civic improvements, which made him an unusually practical figure in the colony's day-to-day growth.
McNair is also remembered as the author of Prisoners Their Own Warders, a book drawn from his experience with the penal settlement in the Andaman Islands. He died in Brighton on 17 May 1910.
