An article on ‘The Radical Club: a 1920s forum for “progressive cultural activity”’ (HI 27.5, Sept./Oct. 2019) referred to a debate at that club on Joyce’s Ulysses in which Liam O’Flaherty and ‘MacManus’ (as identified in Rosamond Jacob’s diaries) were the antagonists. The article’s author, Brian Trench, named Francis MacManus as the debater but now acknowledges it is more likely that it was M.J. MacManus, later literary editor of the Irish Press.
