James Salter in the New York Review of Books:
Ernest Hemingway, the second oldest of six children, was born in Oak Park, Illinois, in 1899 and lived until 1961, thus representing the first half of the twentieth century. He more than represented it, he embodied it. He was a national and international hero, and his life was mythic. Though none of his novels is set in his own country—they take place in France, Spain, Italy, or in the sea between Cuba and Key West—he is a quintessentially American writer and a fiercely moral one. His father, Clarence Hemingway, was a highly principled doctor, and his mother Grace was equally high-minded. They were religious, strict—they even forbade dancing.
From his father, who loved the natural world, Hemingway learned in childhood to fish and shoot, and a love of these things shaped his life along with a third thing, writing. Almost from the first there is his distinct voice. In his journal of a camping trip he took with a friend when he was sixteen years old, he wrote of trout fishing, “Great fun fighting them in the dark in the deep swift river.” His style was later said to have been influenced by Sherwood Anderson, Gertrude Stein, Ezra Pound, journalism, and the forced economy of transatlantic cables, but he had his own poetic gift and also the intense desire to give to the reader the full and true feeling of what happened, to make the reader feel it had happened to him. He pared things down.
