Harry Stuart Goodhart was born on 29 May 1887 in Cambridge, England. He added the additional name Rendel by royal licence in 1902. He was educated at Eton College, and read music at Trinity College, Cambridge. He worked briefly for Sir Charles Nicholson, and then set up his own architectural practice. He is known for his church projects.
He was Oxford's Slade Professor of Fine Art, from 1933 to 1936. His 1934 lectures on Victorian architecture were considered important, as part of the informed revival of interest in Victoriana, by Nikolaus Pevsner. He served as president of the Royal Institute of British Architects (RIBA) from 1937 to 1939.
He was appointed a CBE in 1955.
