A. B. Guthrie Jr., a Kentucky journalist who turned to fiction and won a Pulitzer Prize as one of the century's leading Western historical novelists, died Friday at his home at Choteau, Mont. He was 90.
Carl D. Brandt, his agent, said he died of lung failure. He had been in poor health for several months.
Mr. Guthrie, who won the Pulitzer in 1949 for his novel "The Way West," also wrote the screenplay for the 1953 motion picture "Shane."
His final book, "A Field Guide to Writing Fiction," was published two weeks ago. His published works consisted of six novels, a book of essays, a children's book, a book of poems and five mystery novels.
