Gay Nobel Laureates

And no, not asking after Dag Hammarskjöld or other worthies, rather Nobel Laureates in Literature. Came up last night when we wondered who the first GNLIL was—more sharply the first out GNLIL. This question obviously depends on what we mean by "gay" and "out". My candidates, in chronological order, after a brief flip-thru on my iPhone, were: Thomas Mann (1929), André Gide (1947), and Patrick White (1973). Enumerate and/or discuss!
