Jack McDevitt (born 1935) is an award-winning American science fiction author whose novels frequently deal with attempts to make contact with alien races, and with archaeology or xenoarchaeology.
McDevitt's first published story was "The Emerson Effect" in The Twilight Zone Magazine in 1981. Two years later, he published his first novel, The Hercules Text, about the discovery of an intelligently conceived signal whose repercussions threaten human civilization. This novel set the tone for many of McDevitt's following novels, which focused on making first contact. Frequently this theme is mixed with both trepidation before the unknown and a sense of wonder at the universe.
