David Hagberg (October 9, 1942 – September 8, 2019) was an American novelist best known for his techno-thrillers featuring super-spy Kirk McGarvey. In an interview with The Writer Magazine, Hagberg spoke of his childhood inspiration to become a writer: "I really got the writing bug in the fourth grade when my Teacher read us Little House On The Prairie. At the end of the school year, she said the most astounding thing, 'This woman, Laura Ingalls Wilder, writes these books and she gets paid for it!' Wow! I thought. This is my gig! By the sixth grade, I was writing mystery stories in spiral notebooks."
