Operation Paperclip
Jacobsen's 2014 book, "Operation Paperclip: The Secret Intelligence Program That Brought Nazi Scientists to America" was called "perhaps the most comprehensive, up-to-date narrative available to the general public" in a review by Jay Watkins of the CIA's Center for the Study of Intelligence. "Operation Paperclip" was included in a list of the best books of 2014 by "The Boston Globe". Leading space historian Michael J. Neufeld gave a negative review of the book: “I cannot endorse Operation Paperclip because: it is error-ridden, it produces no fundamentally new information, it is unbalanced, and its notes are poor.”
