Don DeLillo

Don DeLillo (born November 20, 1936) is an American essayist, novelist, playwright, and short story writer. His works have covered subjects as diverse as television, nuclear war, sports, the complexities of language, performance art, the Cold War, mathematics, the advent of the digital age, and global terrorism. Initially a well-regarded cult writer, the publication in 1985 of White Noise brought him widespread recognition, and is considered to be his breakthrough work. DeLillo has twice been a Pulitzer Prize for Fiction finalist for Mao II and Underworld (1992 and 1998, respectively), won the PEN/Faulkner Award for Mao II in 1992 (receiving a further PEN/Faulkner Award nomination for The Angel Esmeralda in 2012), and was granted the PEN/Saul Bellow Award for Achievement in American Fiction in 2010. DeLillo has described his fiction as being concerned with "living in dangerous times", and in a 2005 interview declared, "Writers must oppose systems. It's important to write against power, corporations, the state, and the whole system of consumption and of debilitating entertainments [...] I think writers, by nature, must oppose things, oppose whatever power tries to impose on us."

I don't think there are any combination/disambiguation issues beyond the adoption of the pseudonym Cleo Birdwell for one book 'Amazons...'. The other issues are around spelling - yep it is 'Don', and not 'Dan' - and the presentation, capitalization and spelling of 'DeLillo' which should as stated above in the lead Author tag.
