Lincoln signed a law paying citizens a share of recovered funds if they reported war fraud.
On March 2, 1863, during the Civil War, Abraham Lincoln signed the False Claims Act, also known as the Lincoln Law. The legislation allowed private citizens to file lawsuits on behalf of the federal government against contractors who had defrauded the Union Army, and it entitled them to a share of any recovered funds.1 The law was a response to rampant fraud by military suppliers who sold defective rifles, sick horses, and sawdust-filled provisions to the Army.
The phrase "whistleblower" itself did not enter common usage until the 1960s and 1970s, when consumer advocate Ralph Nader popularized it as a positive alternative to "snitch" or "informer."2 Nader argued that people who reported wrongdoing within organizations were performing a public service, and the language should reflect that. The metaphor came from a referee's whistle, signaling a foul.
The Whistleblower Protection Act of 1989 established federal protections for government employees who disclosed evidence of waste, fraud, or abuse.3 The Sarbanes-Oxley Act of 2002, passed after the Enron and WorldCom scandals, extended protections to employees of publicly traded companies.4 The Dodd-Frank Act of 2010 created a bounty program at the Securities and Exchange Commission, paying whistleblowers between ten and thirty percent of sanctions exceeding one million dollars.5
Between 2012 and 2023, the SEC awarded more than $1.8 billion to whistleblowers who provided information leading to successful enforcement actions.6 The legal architecture built over 160 years reflects an unresolved tension in organizational life: the same institutions that depend on internal loyalty to function also depend on internal dissent to stay honest.
