'Samuel Simmons was a Melbourne printer who established two small private presses, the Argonaut Press and The Simmons Press, which published his own verse and criticism and other works, e.g. the poems of the English writer Christopher Smart. Of Simmons's six books, the most important were Sonnets and Other Verses (1925), published under the pseudonym 'Oswald Gray', and A Problem and a Solution (1946), a textual study of Marcus Clarke's first novel, Long Odds (1869). A prominent member of the Bread and Cheese Club, Simmons also prepared a bibliography of Clarke which was enlarged by L.T. Hergenhan and published in 1975.' (Oxford Companion to Australian Literature)
