Drunk drive blend two of America ’s favorite pastimes : getting absolutely hammered and drive an automobile . But before the innovation of the modern breathalyser in the 1950s , determining if someone was too intoxicated to operate a motor vehicle was improbably subjective . It took decades for law enforcement engineering to catch up with one of our most pervasive crimes .
Welcome to Gizmodo’sHappy Hour . Substance ill-treatment for nerds .
Before the advent of the motorcar , being drunk was a relatively minor nuisance for companionship at large . Most of the meter , imbibing too much of your preferred poison did little to put strangers in harm ’s way . The automobile , with its incredible speeding and considerable weight , changed all that . Today , or so 30 % of America ’s traffic fatality involve a intoxicated machine driver . Back in the 1950s and ‘ 60 , that percent was closer to 50 % .
Those astonishing numbers game kicked off the pastime of a simple gadget , one that could determine any suspect ’s guilt with the push of a clitoris . That was the Leslie Townes Hope ( and fear ) of people who were fighting over the development of the very first breathalyzer technologies .
The Bad Old Days
After World War I , the car was becomingincreasingly popularon American roads . What had once been a plaything of the rich was quickly chance its way into the hands of people with more modest income . And despite the handing over of inebriant inhibition in 1920 , more and more Americans were getting drunk before slide behind the roulette wheel .

The first serious scientific workplace on mechanizing the determination of whether someone was driving drunk choose place in the twenties . A MD and researcher in Los Angeles by the name of Dr. Emil Bogen conducted alandmark studyin 1927 on how to scientifically decide tipsiness . By this clip it was fairly well - established that testing blood devote you a solid estimate of how drunk a person might be . But by testing urine , blood , and breath , Bogen recover that the latter could indeed function as a honest estimator for blood alcohol substance ( BAC ) .
Dr. Bogen ’s breath testused a big football bladder that stop sulphuric acid and potassium dichromate . A affected role would breathe into it , and as the chemicals in the football game bladder change from yellow to various shades of disconsolate and green , they were compare to underground of the same chemicals in which different amounts of alcohol had been added . Effective , but not the most virtual for a dealings full point .
Another somebody whose early study would contribute to the birthing of the breathalyzer was W.D. McNally in Chicago . The delineation above pass in the November 1927 issue of Science and Invention magazine exhibit off McNally ’s “ breath analyser . ”
McNally was a chemist whose former breathalizer - corresponding gadget used the same principles as Dr. Bogen ; blowing into the tube of the gimmick would cause the chemicals to turn a light-green hue if there was any alcohol present . pic of McNally ’s equipment ran in popular tech magazines , anticipate that before long , there would be a dependable and objective way to set if someone had indeed been ride drunk .
The Post-Prohibition Surge
By the other 1930s , more and more investigator in the United States and Europe were becoming concerned in unlike fashion to quiz for intoxication . And for good reason .
The prohibition on alcoholic beverage was repealed in the U.S. in later 1933 , make an even corking sense of urgency among public health officials and scientist who were concerned about drunk driving . Too many people were die on the nation ’s roads , and it was clear that alcoholic drink was a major factor . In Chicago , drunk driving deaths quadrupled in the first six months of 1934 over the same time the yr before . In Los Angeles , city officials noted a like rise in drunk drive injuries and fatalities .
A biochemist at Indiana University by the name of Dr. Rolla N. Harger first declare his own method for measuring alcoholic beverage by means of a breath test in 1931 . By 1938 , Harger had a working twist that was being tested by the Indiana State Police . The first real - globe trial of Harger ’s machine was conducted by the Indiana State Police on December 31 , 1938—75 year ago today . By 1940 , other police force departments around the country were using Harger ’s machine , picture above at the New Jersey Police Department that twelvemonth .
When the great unwashed asked Harger ( pictured below ) and his inquiry squad what they call their new intoxicant breath analyzer , they jokingly said the “ Drunkometer . ” But joke or not , the name really stuck .
Harger ’s was n’t the only breathalizer on the food market compete for care . There was also the Alcometer , developed in theearly 1940sby Leon Greenberg and Frederic Keator at Yale , as well as the Intoximeter , visualize below in manipulation by the L.A. Police Department .
These machine went by unlike names , but they all utilize the same principles : comparing the proportion of carbon dioxide and alcohol in a person ’s breath to pre - interracial inebriant solution . These were then translated to the tantamount measurements in the blood .
But even as the engineering slowly evolved and meliorate in the first one-half of the twentieth hundred , the qualifications for what was considered “ too drunk ” to drive also changed .
Pushing the Limits
Scandinavian countries were ahead of the curve in adopting strict limits on drunk driving . In his 2011 bookOne For The Road , Barron Lerner explains that Norway ’s BAC limit was 0.05 % by 1936 , while Sweden ’s was 0.08 % by 1941 .
But Americans were much more lenient when it came to drunk driving . Even as late as the sixties , American courts in many states regard anything less than 0.15 % as probably not worthy of criminal prosecution , still adhering to guidelines arrange up in 1939 by the National Safety Council and the American Medical Association . They gave three mountain chain for BAC , which would become the standard in a absolute majority of land legislatures :
0.05 % and below : defendant should not be consider under the influence
0.05 % to 0.15 % : Not considered “ under the influence ” but taken into chronicle if other evidence is portray
0.15 % and above : Presumed “ under the influence ” of alcohol
Fascinatingly , the justice organisation was specially lenient in part because of the many late unsuccessful person of alcohol prohibition in the U.S. during the 1920s . Even organizations like the AMA and the NSC thought it well not to be too harsh on people who drive intoxicated .
As Lerner notes inOne For The Road :
Well cognizant of the of late concluded and highly criticized ban experiment , [ AMA and NSC ] committee member erred far on the side of mildness when it total to the apprehensiveness and prosecution of impaired and drunk drivers . As Stanford University brain doctor and potomania expert Henry W. Newman later explained , “ We would not care to see a parallel to prohibition occur here , with the subsequent revulsion of feeling and the licence that followed after prohibition which still prevails to a sure extent at the present clock time . ”
Today , the federal limit in the U.S. is 0.08 % . That ’s much more in line with other countries , but still more free than most .
Boozer Boom
America saw another plosion in automobile ownership after WWII , as enlargement of the suburbs caused many people to drive bully distance ( with and without a drunkenness ) than ever before .
But examination for poisoning was incredibly controversial , even in the 1950s . myriad people tried to dispute the efficaciousness of the gadget . Could Harger ’s Drunkometer really concord up in a royal court of law ?
In 1950 , Harger write a defense of his invention for the American Journal of Police Science . Titled,“Debunking ” The Drunkometer , Harger outlined the many ways in which his new gadget had been challenged over the last decade . Harger fare out swing , apace knocking down every possible criticism and each way people could allegedly beat the test .
One criticism published in a letter to the Journal of the American Medical Association in 1940 claimed that a deficiency of oxygen would make a false positive in chemical exam for intoxication . So what did Harger do ? He drown 50 rabbit in his lab and took descent tests , show that there were no false positives for tipsiness in the dead animals . Not very nice for the rabbit , but Harger certainly proved his peak .
Another criticism continually leveled against Harger and his ilk was the fact that breath mental test are n’t a unmediated measure of inebriant in the lineage . Lawyers and lobbying grouping contended that because every breathalyzer had to convert the alcoholic beverage - carbon copy dioxide ratio that it find into a parentage balance to be understood as BAC , they were undependable .
With over two decades of research now under his belt , Harger was more than ready to contest these claim . His Drunkometer , though , was about to get usurped by a new technology for roadside breath testing .
Enter the Breathalyzer
In 1954 Robert F. Borkenstein invented the Breathalyzer . Borkenstein had been hired as a police photographer at the Indiana State Police science lab in 1936 , and cursorily became interested in drunk driving thanks to the piece of work of Harger and his Drunkometer .
As Lerner explains :
Over the next seventeen years , Borkenstein , work up on his work with colour picture taking , conceptualized a gadget that would improved on the earlier one . Then , in February 1954 , during his annual two - workweek vacation , he build up [ the Breathalyzer ] in the cellar of his dwelling house . The Breathalyzer , in Borkenstein ’s own word , was “ so surprisingly simple — two photo cells , two filters , a equipment for roll up a breathing spell sample , about six wires . ”
constabulary department were becoming more and more interested and confident in breath test technology , thanks in big part to the advancements of Borkenstein ’s technology . depart were the football bladders and complex solutions that needed to be ruffle , in their place a gadget whose reliability — and portability — would truly set it up as an essential tool in every police force officer ’s toolkit .
Push-Button Justice
During the fifties , the American public and the judicial system were still erring on the side of the drunk driver . peculiarly enough , some people were concern that the automation of measuring sobriety was somehow not fitting with the American way . With an attitude that seems counterintuitive to many of us here in the 21st century , mass did n’t trust machines more than a cop ’s testimony of slur speech or sloppy behavior .
Opponents even had a name for the rise of technologies like the breathalizer : push - button Department of Justice .
A 1955 article in theVirginia Law Reviewby Edwin Conrad explain that the concerns about push push justice were even larger than just one proceeds . Conrad argued that new scientific advancement — such as improved photographic technology , radar for measuring traffic speed , and yes , Drunkometers for find a driver ’s level of intoxication — should be embraced to move social club and the field of criminal justice forward .
Push - button jurist was nearly here . But American public attitudes were still seemingly stuck in the 1930s .
The sixties brought about a turning distributor point in the public health community . Borkenstein conduct a landmark subject in 1964 known as the Grand Rapids Study which concluded that there was a definitive link between increased BAC and car stroke . Amazingly , people were still debating in the 1960s whether drunk driving really posture a endangerment on the Carry Amelia Moore Nation ’s roadstead .
Just a few years subsequently , in 1968 a study by the U.S. Department of Transportation found that about half of the nation ’s machine fatalities ( about 25,000 deaths ) involved alcohol . slow but sure over the course of the next two decade , Americans would come to see drunk driving as without dubiousness dangerous and immoral . And the technology for prove BAC ( which wouldbecome electronicby the destruction of the 1970s ) would help put an end to an era that some people called the Golden Age of Drunk Driving .
Tonight , police officers will be out in full force looking for intoxicated driver . And some department ( likethe LAPD ) even have new tests to speedily gauge whether a number one wood has been using any other forbidden substances — like marijuana , cocain , or even prescription drug drugs like Xanax .
With the legitimation of marijuana for recreational function in states like Colorado , society is yet again debating what satisfactory levels of intoxication there may be before someone gets behind the wheel . Only this time it seems that marijuana has an acclivitous battle . At the beginning of the twentieth hundred , drunk equipment driver start with the benefit of the doubt and social norms evolved to a point of crushed leeway for such behavior . unluckily for fans of weed , they ’re start here in the twenty-first C with just the opposite .
