Cryptologic Career Beginnings

First Cryptologic Work Riverbank Laboratories, 1916
Initial Role Cipher research assistant on Shakespeare-Bacon theory
Key Colleague William F. Friedman
Marriage May 1917

After visiting the Newberry Library in Chicago in 1916, Elizabeth learnt about cryptography from George Fabyan’s Riverbank Laboratories. She swiftly graduated to more complex codebreaking after being hired to decipher Shakespeare’s cyphers. William Friedman and her discovered cypher theory problems and became professional partners and wives.

World War I and Government Service

WWI Military Role Army Signal Corps Consultant, 1917–1919
Location Washington, D.C.
Contribution Trained first U.S. cryptanalysts
Specialization Military codebreaking and instructional programs

During World War I, Elizabeth and William helped establish the first systematic cryptanalysis training program for U.S. military personnel. Their work laid the foundations of modern American cryptographic efforts.

Prohibition Era and U.S. Coast Guard

Year Joined Coast Guard 1925
Messages Decoded Annually ~12,000
Unit Established 1931 – First Coast Guard Cryptanalysis Unit
Major Opponent Organized crime syndicates, including Al Capone
Primary Tool Radio signal interception and decryption

Between the wars, Elizabeth reentered public service to combat Prohibition-era smuggling. Working with the Coast Guard, she intercepted and deciphered thousands of coded radio messages from bootleggers and traffickers. Her courtroom testimony helped convict major players in narcotics and alcohol crime rings.

World War II: Strategic Intelligence

World War II Assignment U.S. Navy Intelligence (ONI), reassigned from Coast Guard
Spy Networks Exposed Axis agents in South America, German command links
Major Case Velvalee Dickinson (Doll Lady case)
Confidentiality Period Until declassification in 2008
Key Contribution Prevented attacks on Allied ships, including Queen Mary

Despite being reassigned under male officers during WWII, Elizabeth’s codebreaking was crucial in dismantling Nazi spy networks operating in the Western Hemisphere. She also assisted the FBI in exposing covert communications disguised as letters about dolls—work for which others received credit publicly.
