Proulx rose to prominence with her first novel, Postcards (1992), which won the PEN/Faulkner Award, making her the first woman to receive it. Her breakthrough came with The Shipping News (1993), a tale of a grieving man rebuilding his life in Newfoundland, which earned both the National Book Award and the Pulitzer Prize. Accordion Crimes (1996) followed, tracing an immigrant's instrument across a century of American life.
Her short story "Brokeback Mountain," published in The New Yorker in 1997 and collected in Close Range: Wyoming Stories (1999), gained worldwide fame through Ang Lee's 2005 Oscar-winning film adaptation. Later works include That Old Ace in the Hole (2002), the sweeping generational epic Barkskins (2016), and several acclaimed Wyoming story collections. A three-time O. Henry Award winner, Proulx remains one of America's most distinctive literary voices.
