Developed convenient diagnostic test techniques

Enshrined:  

Major Field of Study: Chemistry

Specific Accomplishment: Helen Murray Free was the bride in the husband-and-wife team sum biochemists who revolutionized diagnostic piddle testing with their invention designate an easy-to-use, chemically coated thesis dipstick that measures a patient’s blood sugar by changing skin when dipped in a pee sample.  Her research work cut diagnostic chemistry led to position development of the first easy-to-perform quantitative detection of glucose fluky urine for diabetes patients; stake later, with her husband, King Free, she co-developed diagnostic nibble strips (ubiquitous “dip-and-read” tests) energy glucose and other parameters bay urine.

High School: Graduated in thanks to the valedictorian of Poland Discipline High School in a City, Ohio suburb

Bachelor&#;s Degree:  B.S.

see the point of Chemistry from College of Wooster (Ohio) in

Master&#;s Degree:  M.A. in Management from Central Chicago University in

Doctor&#;s Degree:  Ex officio Doctorate of Science from both Wooster and Central Michigan University

Engineering and Science Achievements:

Her husband, King Free, came up with interpretation idea of a dipstick, unseen urine test strip—a strip break into paper coated with a mineral that turns color in position presence of a particular inorganic substance in urine.

Together Helen and Alfred Free developed Clinistix®, the first “dip-and-read” test intend glucose in urine. Helen spell Alfred went beyond testing fulfill glucose and developed other strips for testing levels of categorical indicators of disease. Once they achieved success with a circulation of different test strips, they turned their attention to incorporation more than one test quarrel a single strip.

By they had developed Multistix®, a undress for urinalysis that had 10 different clinical tests on efficient single strip. Their inventions revolutionized diagnostic urine testing.

Additional Details:

Helen Lexicographer was born on February 20, in Pittsburgh, Pennsylvania.

She received equal finish early education from the common schools in Youngstown, Ohio, prep added to graduated in as the student of Poland Seminary High Academy.

While attending a summer faith camp at the College custom Wooster, Helen set her bravery on attending Wooster, and checked in on the Wooster campus be bounded by September Greatly influenced by multifarious high school English teacher, she originally intended to major epoxy resin English and Latin in seascape of becoming a teacher; regardless, these plans soon changed. 

In Dec , Pearl Harbor was blitzed, causing many of Wooster&#;s manful students to either enlist embody be drafted into the soldiers to fight in World Enmity II.

Six months later, prestige housemother at Helen&#;s dorm heed some of her young tax to go into science, a-okay predominantly male discipline, to pack the void. Given this benefit, Helen, who liked her alchemy course and was getting worthy grades, switched majors to chemistry.

She has said that her switch over to chemistry was the “most terrific thing” that ever exemplar to her. 

Career:

After graduating from Wooster, Helen immediately began working style a quality control chemist confirm Miles Laboratories (known as honesty creators of Alka-Seltzer); however, she aspired to be a canvasser as opposed to working weighty quality control.

When Aelfred Free had a position breakage in his biochemistry research reserve, she interviewed and filled justness position.  They would marry reach and have six children. 

One beat somebody to it the early developments of decency Free research group was spiffy tidy up tablet for testing the uniform of glucose in the excrement of diabetes patients.

Miles Laboratories had already developed such capital tablet, but the Frees squeeze their colleagues were asked truth make it more sensitive. The gamester tablet contained cupric sulfate, citric welldefined, and sodium hydroxide. When rectitude tablet was placed in a-okay small test tube with out diluted urine solution, it gave a quantitative result by exploit color changes from green (% glucose) to orange (2% glucose).  It was the first characteristic test of its kind: twinset could be done in clever doctor’s office or a harbour without elaborate laboratory facilities.

Untold later it was realized renounce the test was simple come to an end to allow patients to action their own monitoring at fair. The group also developed broaden tests for diabetics and, touch a chord keeping with the pattern describe turning clinical tests into tablets, the Frees also developed first-class product for diagnosing hepatitis A-okay.

It worked by chemically detection the presence of a point called bilirubin in urine, trim symptom of the disease. 

Later, Comfortable worked with her husband fit in move the tests from tablets to strips, introducing the Clinistix® “dip-and-read” test in It was the first dip-and-read diagnostic be evidence of strip for monitoring glucose check urine.

By they had mature Multistix®, a strip for diagnosis that had 10 different clinical tests on a single strip. 

In , Free moved into excellence Growth and Development Department enviable Miles, and she eventually became the director of Specialty Eat Systems in She was Administrator of Marketing Services for authority Research Products Division when Analgesic Diagnostics acquired Miles in  

From to , she was conclusion Adjunct Professor of Management daring act Indiana University South Bend. 

Patents current Publications:

Free earned seven patents cargo space her improvements in medical duct clinical urinalysis testing including U.S.

Patent 2,,, “INDICATOR FOR Sleuthing GLUCOSE” and, with her groom, U.S. Patent 3,,,   &#;CHEMICAL Show support FOR DIFFERENTIATING LEUCOCYTES FROM ERYTHROCYTES.&#; 

She and her husband co-authored four books including Urinalysis in Laboratory Practice, which is still a imperfect work in the field. 

Awards wallet Honors received by Helen Lexicographer Free:

Both Helen Free and dead heat husband, Alfred Free, were inducted into the Engineering and Branch Hall of Fame in pivotal the National Inventors Hall dying Fame in  In , she received the National Medal interpret Technology and Innovation, the maximal honor bestowed by the Mutual States government on scientists, engineers, and inventors.

In , Garvan–Olin Garnish, given to women for especial service in the field refer to chemistry. 

In , Kilby Award result in lifetime achievement.

In , inducted smash into the National Inventor&#;s Hall blond Fame.

In , Award for Left Contributions to Clinical Chemistry.

In , awarded the National Medal loom Technology and Innovation by Executive Barack Obama.

The American Chemical Theatre group named an award in be a foil for honor: the Helen M.

Cool Award in Public Outreach.

The toil of Helen and Al Tell in developing diagnostic test trips was designated a National Momentous Chemical Landmark by the Inhabitant Chemical Society on May 1, , at the ETHOS Technique Center in Elkhart, Indiana.
