He was born in Macroom, County Cork, and educated at St Patrick's Teacher Training College in Drumcondra, Dublin.
Maume cites Daniel Corkery comparing their different styles "...how Murray often achieves a kind of hidden tension -the very stuff of drama- that Synge only rarely reached and Sean O'Casey knows nothing of".
Maume cites the example of Murray's early play 'Maurice Harte' wherein "a clerical student who lacks a vocation is driven mad by the pressure of family expectations".
[citation needed] It has been stated both by A. DeGiacomo and by R. Allen Cave that, in the Art competitions at the 1924 Olympics in Paris, France, Murray was awarded a bronze medal for his play Birthright.
However, according to the official record for the games, although Murray was a participant in the literature category with this play and also with Maurice Harte he did not win a medal.
