Henry Graham Greene (2 October 1904 – 3 April 1991) was an English writer and journalist regarded by many as one of the leading novelists of the 20th century.
Combining literary acclaim with widespread popularity, Greene acquired a reputation early in his lifetime as a major writer, both of serious Catholic novels, and of thrillers (or "entertainments" as he termed them). He was shortlisted for the Nobel Prize in Literature several times. Through 67 years of writing, which included over 25 novels, he explored the conflicting moral and political issues of the modern world. The Power and the Glory won the 1941 Hawthornden Prize and The Heart of the Matter won the 1948 James Tait Black Memorial Prize and was shortlisted for the Best of the James Tait Black. Greene was awarded the 1968 Shakespeare Prize and the 1981 Jerusalem Prize. Several of his stories have been filmed, some more than once, and he collaborated with filmmaker Carol Reed on The Fallen Idol (1948) and The Third Man (1949).
He converted to Catholicism in 1926 after meeting his future wife, Vivien Dayrell-Browning.
