Arthur Karmen, M.D. established the first global standard for measuring blood transaminases (AST/ALT) to diagnose myocardial infarctions (heart attacks) and liver disease.

In 1954, Dr. Karmen developed the definitive enzymatic method for detecting transaminase activity in blood serum. This discovery allowed physicians to definitively confirm tissue damage following a heart attack or during active liver disease.

In the 1950s, Dr. Leonard T. Skeggs Jr. invented the AutoAnalyzer in his basement, which was commercialized by the Technicon Corporation in 1957 and evolved into the modern Chem 7.

Technicon expanded Skeggs’ continuous-flow technology into sequential multiple analyzers (SMA and SMAC systems) in the late 1960s and 1970s, which allowed laboratories to perform panels of multiple biochemical tests simultaneously from a single blood sample. Grouping these specific seven tests together became routine clinical practice as automated multichannel machines became widespread.

Beyond engineering instruments, he conducted vital medical research at the VA Hospital in Cleveland. Alongside Joe Kahn, he successfully isolated and discovered Angiotensin I and II, and discovered the Angiotensin-Converting Enzyme (ACE). This breakthrough laid the groundwork for ACE inhibitors, which are now taken by millions globally to treat high blood pressure.

Wallace H. Coulter patented the Coulter Principle—using electrical impedance to rapidly count and size microscopic cells—and introduced the Model A electronic counter, making the modern automated CBC possible.

Wallace H. Coulter was an American electrical engineer, inventor, and businessman. The best known of his 85 patents is the Coulter principle, which provides a method for counting and sizing microscopic particles suspended in fluid.

Dr. Scipione Riva-Rocci introduced the modern inflatable blood-pressure cuff (sphygmomanometer) in 1896.

Scipione Riva Rocci was an Italian internist, pathologist and pediatrician. He is best known for the invention of an easy-to-use cuff-based version of the mercury sphygmomanometer for the measurement of blood pressure.

About

What is the Doctor Hall of Fame? In medical school, I made up an award called the Student’s Choice Award and gave it to the professor in the lecture-based learning program who actually taught us the material. Everyone else would just go through PowerPoint slides that somehow referenced the textbooks we were supposed to be reading. None of us read the textbooks, though, because the tests were based on stuff in the PowerPoints. So we just memorized a bunch of PowerPoints for each topic. I only did the lecture-based method of learning because all the girls in the class were in that program and not the independent study program. The independent study program was where you read the textbooks. Sometimes I wish I really had done the independent study program and read all those books. But I’ll never forget all the fun times we had in class. My best moment, I think, was when I gave this award called the Student’s Choice Award to the pharmacology professor, and he was so happy that he got an award. That’s what the Doctor Hall of Fame is about: actually giving an award to people who made a difference in medicine.

Dr. Mary Edwards Walker was the first female surgeon in the United States, serving as a Union Army surgeon during the American Civil War.

Career and Civil War Service

Education: Graduated with an M.D. from Syracuse Medical College in 1855.

Military Appointment: Initially rejected due to her gender, she volunteered as a nurse and surgeon before becoming the Army’s first official female surgeon as a civilian contract surgeon in 1863.

Medal of Honor: Awarded the Congressional Medal of Honor in 1865 by President Andrew Johnson; she remains the only woman to receive the award.

Dr. Marie Curie pioneered the therapeutic use of radiation to destroy diseased cells and treat tumors, forming the basis of modern radiation oncology.

Coined “Radioactivity”: She established that radiation was an atomic property of an element rather than an interaction between molecules. She also utilized the Curie electrometer (invented by Pierre and Jacques Curie) to measure faint electrical currents caused by radiation.
