Robert Philip Hanssen (born April 18, 1944) is a former US Federal Bureau of Investigation (FBI) agent who spied for Soviet and Russian intelligence services against the United States for 22 years from 1979 to 2001. About the book: https://www.amazon.com/gp/product/0802139515/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0802139515&linkCode=as2&tag=tra0c7-20&linkId=4ec737c6ddd2977f57812083023f31bc

He is currently serving 15 consecutive life sentences at ADX Florence, a federal supermax prison near Florence, Colorado.

Hanssen was arrested on February 18, 2001 at Foxstone Park near his home in Vienna, Virginia, and was charged with selling US secrets to the USSR and subsequently Russia for more than US$1.4 million in cash and diamonds over a 22-year period.[3] On July 6, 2001, he pleaded guilty to 15 counts of espionage in the United States District Court for the Eastern District of Virginia. He was then sentenced to 15 life terms without the possibility of parole. His activities have been described by the US Department of Justice's Commission for the Review of FBI Security Programs as "possibly the worst intelligence disaster in U.S. history".

The story is mentioned in Ronald Kessler's book The Secrets of the FBI, both in Chapter 15, "Catching Hanssen," and Chapter 16, "Breach."

Eric O'Neill's role in the capture of Robert Hanssen was dramatized in the 2007 film Breach, in which Chris Cooper played the role of Hanssen and Ryan Phillippe played O'Neill.[67]

The 2007 documentary Superspy: The Man Who Betrayed the West describes the hunt to trap Robert Hanssen. Hanssen also was the subject of a 2002 made-for-television movie, Master Spy: The Robert Hanssen Story, written by Norman Mailer and starring William Hurt as Hanssen. Robert Hanssen's jailers allowed him to watch this movie but Hanssen was so angered by the film that he turned it off.[68]

Hanssen is mentioned in chapter 5 of Dan Brown's book The Da Vinci Code as being an FBI spy and Opus Dei member but also a sexual deviant.[69]

The 2002 book written by David Wise and titled Spy: The Inside Story of How FBI's Robert Hanssen Betrayed America covers the case in detail.

Hanssen graduated from William Howard Taft High School in 1962 and went on to attend Knox College in Galesburg, Illinois, where he earned a bachelor's degree in chemistry in 1966. While at Knox, he took an interest in Russian through elective courses.

It was also at this time when Hanssen applied for a cryptographer position in the NSA but was rebuffed due to budget setbacks. Originally set to become a doctor, Hanssen took the opportunity to enroll in the dental school at Northwestern University.[10] He did well academically, but said that he "didn't like spit all that much".[11] He switched his focus to business after three years,[12] and received an MBA in accounting and information systems in 1971. After graduating, he took a job with an accounting firm but quit to join the Chicago Police Department as an internal affairs investigator, specializing in forensic accounting. Hanssen left the department after four years, joining the FBI in January 1976.[7]

Hanssen met Bernadette "Bonnie" Wauck while he was attending dental school in Chicago. Bonnie was one of eight children from a staunchly Roman Catholic family. The couple married in 1968. After Hanssen married, he converted from Lutheranism to his wife's Catholicism, becoming a fervent believer and being extensively involved in Opus Dei.
