Graham Greene (1904–1991) was an English novelist and journalist recognized as one of the foremost writers of the 20th century. Over a career spanning 67 years, he published more than 25 novels that combined literary depth with popular appeal. His work often explored complex moral and political themes, frequently through the lens of his Catholic faith, which he adopted in 1926 though he later described himself as a "Catholic agnostic." Notable novels include *The Power and the Glory*, which won the 1941 Hawthornden Prize, and *The Heart of the Matter*, recipient of the 1948 James Tait Black Memorial Prize. Several of his works, such as *The Third Man* and *The Fallen Idol*, were adapted into acclaimed films, the former in collaboration with filmmaker Carol Reed. Greene’s writing is noted for its psychological insight and exploration of human contradictions, with settings often reflecting geopolitical turmoil or moral ambiguity, a style sometimes referred to as "Greeneland." Though twice shortlisted for the Nobel Prize in Literature, he never won. His influence extends beyond literature into film and political commentary. Biographers emphasize his adventurous life—marked by global travels, journalistic work, and complex personal relationships—as well as the cultural and historical contexts that shaped his oeuvre. He passed away in 1991 from leukemia and is buried in Switzerland. Contemporary scholarship, including a recent biography by Richard Greene, continues to reassess his legacy, highlighting the political and cultural significance of his work in understanding the 20th century[1][2][3][6].
