John Augustus Larson (11 December 1892 – 1 October 1965) was a Police Officer for Berkeley, California, United States, and famous for his invention of modern polygraph used in forensic investigations.[1] He was the first American police officer having an academic doctorate and to use polygraph in criminal investigations.[2][3] After a famed career in criminal investigation, he died of heart attack in Nashville, Tennessee at the age of 72.[4]

Early life and career[edit]

Larson was born in Shelburne, Nova Scotia, Canada, of Nordic parents. His family moved to New England in his early childhood, though his parents soon divorced. He studied biology at Boston University holding down odd jobs to support himself, ranging from busboy and paperboy to stonecutter and elevator operator. In 1915, he earned a master's degree with a thesis on fingerprint identification. This work inspired his interest in forensic science and led him to the University of California, Berkeley, where he obtained a Ph.D. in physiology in 1920.[5]

Having done moonlighting work as a student for the Berkeley Police Department, he joined the force in 1920. His great insight was to integrate a test for blood pressure, developed by William Moulton Marston, with measurements for pulse, respiration and skin conductivity, to make a comprehensive lie detection tool. He was also highly encouraged by his police chief August Vollmer.

At the time of the invention of the polygraph, Larson was a 21-year-old medical student at the University of California, Berkeley. He later entered the field of forensic psychiatry.

Invention of polygraph[edit]

The instrument, with its diverse collection of physiological indices, became known as the polygraph, which Larson then fully developed for forensic use in 1921, and applied it in police investigations at the Berkeley Police Department.[6][7] His instrument provided continuous readings of blood pressure, rather than discontinuous readings of the sort found in Marston's device. The first practical use was in the summer of 1921. The San Francisco Call and Post arranged for Larson to use the apparatus to test William Hightower, accused of murdering a priest in San Francisco. The newspaper reported Larson’s findings the following morning: Hightower was pronounced guilty by impartial science. The graphic results of the interrogation were printed large across the page, with arrows marking each presumed lie. Vollmer exalted the machine to the press, which renamed it the 'lie detector.' However, Larson himself used to refer to his apparatus as a 'cardio-pneumo psychogram,' which basically consisted of a modification of an Erlanger Sphygmomanometer.[8]

Legacy[edit]

Larson married Margaret Taylor, the freshman victim of the College Hall case and the first person he ever interrogated on the lie detector. Over the next fifteen years, he collected hundreds of files on successful criminal cases where his polygraph solved murders, robberies, thefts and sex crimes. His instrument was nicknamed 'Sphyggy' by the press who covered Larson’s crime solving escapades in the 1920s and 30's; Sphyggy because they couldn’t pronounce 'Sphygmomanometer.' [9] The polygraph is considered officially one of the greatest inventions of all time. It is included in the Encyclopædia Britannica Almanac 2003's list of 325 greatest inventions.[10] This first polygraph instrument of Larson is now at the Smithsonian Institution in Washington, D.C.. It first appeared in action in a moving picture in 1926 in the silent police serial ‘’Officer 444’’.
