Ivan Doig, an award-winning author whose books set in his native Montana made him one of the most respected writers of the American West, died April 9 at his home in Seattle. He was 75.

The cause was multiple myeloma, Geoff Kloske, the publisher of Riverhead Books, said in a statement.

Mr. Doig wrote 16 books, including the McCaskill trilogy, three novels about a fictional Montana family covering the first 100 years of the state’s history. His 1979 memoir, “This House of Sky,” chronicling his childhood in a remote and forbidding region of Montana, was a finalist for the National Book Award.

In 2007, Mr. Doig won the Wallace Stegner Award, which recognizes someone who has “made a sustained contribution to the cultural identity of the West.” He was also the recipient of the Western Literature Association’s Distinguished Achievement Award.

Ivan Doig was born June 27, 1939, in White Sulphur Springs, Mont. The former ranch hand earned bachelor’s and master’s degrees in journalism from Northwestern University and a PhD in history from the University of Washington.

His publisher said that two of Mr. Doig’s later works, “The Bartender’s Tale,” released in 2012, and the yet-to-be published “Last Bus to Wisdom,” were inspired by experiences from the author’s youth.

Mr. Doig’s writing gained him many admirers, including Australian author Thomas Keneally, who said Mr. Doig was “one of the great American voices, full of grace, abounding in humanity, easeful in narration, hypnotic in pace, grand in range.”

Survivors include his wife of 49 years, Carol Muller Doig.
