Henry Jones Underwood (1804–1852) was an English architect who spent most of his career in Oxford.
[2] Underwood trained in London as a pupil of Henry Hake Seward and then joined the office of Sir Robert Smirke.
[3][4] In 1830 he moved to Oxford where much of his work involved designing churches or schools.
[citation needed] Underwood designed an extension to Oxford Prison.
In 1852 he committed suicide at the White Hart Hotel, Bath, Somerset[3] so J. C. Buckler completed the extension in his stead.
