Ivor John Carnegie Brown (1891-1974) was a British journalist and man of letters.
Born in Penang, Malaya, Brown was the son of Dr. William Carnegie Brown, a specialist in tropical diseases, and his wife Jean Carnegie. At an early age he was sent to Britain, where he attended Suffolk Hall preparatory school and Cheltenham College. After additional private instruction, he was accepted into Balliol College, Oxford, graduating with double degrees in Classics and Literae Humaniores.
Brown spent his final years concentrating on writing books. He would eventually publish over 75 books covering a wide range of topics and genres, but he was best known for his works on literature and the English language. He was chairman of the British Drama League from 1954 to 1962 and a fellow of the Royal Society of Literature, and he was named a CBE in 1957. He died in London in 1974.
