Leonardo da Vinci
He studied and recorded the anatomy of the body -
1550
Gabrielle Fallopius
She discovered the fallopian tubes of the females anatomy. -
1563
Bartolommeo Eustachio
He discovered the tube leading from the ear to the throat (Eustachio tube) -
William Harvey
He used his knowledge to understand physiology, and he was able to describe the circulation of blood and the pumping of the heart. -
Antonie von Leeuwenhoek
He invented the microscope, establishing that there is life smaller than the eye can see. He scraped his teeth and found the bacteria that causes tooth decay. -
Apothecaries
Apothecaries, early pharmacies, started in this time in medieval England, these apothecaries engaged in a flourishing trade in drugs and spices from the East. -
Period: to
The 18th century
-
Benjamin Franklin
His discoveries affect us in many ways. His discoveries include bifocals, and he found that colds could be passed from person to person. -
Medical students learning
Students not only attended lectures in the classroom and laboratory, but also observed patients at the bedside. When a patient died, they dissected the body and were able to observe the disease process. This led to a better understanding of the causes of illness and death. As this continued, more new discoveries were made. -
Joseph Priestley
he discovered the element oxygen. He also observed that plants refresh air that has lost its oxygen, making it usable for respiration. -
Edward Jenner
he discovered a method of vaccination for smallpox. Smallpox killed many people in epidemics. His discovery saved millions of lives. Furthermore, his discovery also led to immunization and to preventive medicine in public health . -
Rene Laennec
He invented the stethoscope. The first stethoscope was made of wood. It increased the ability to hear the heart and lungs allowing doctors to determine if disease was present. -
Period: to
The 19th and 20th centuries
-
Ignacio Semmelweis
He identifies the cause of childbed fever. Large numbers of women died from this fever after giving birth. He noted that the patients of midwives had fewer deaths. When this was happening the physicians never washed their hands when they delivered babies. Their hands were dirty and affected the women. Semmelweis realized this was happening and now to this day washing your hands and having proper sanitation systems are the most important when it comes to spreading infections. -
Florence Nightingale
She is the founder of modern nursing -
Louis Pasteur
He is known as the “Father of microbiology,” discovery that tiny microorganisms were everywhere. Through his experiments and studies, he proved that microorganisms were created by disease. He also discovered that heating milk prevented the growth of bacteria. -
Dimitri Ivanovski
In 1892 in Russia, Dimitri discovered that some diseases are caused by microorganisms that cannot be seen with a microscope. They are called viruses. -
Joseph Lister
He learned about Pasteur’s discovery that microorganisms cause infection. He used carbolic acid on wounds to kill germs that cause infection. Then, he became the first doctor to use an antiseptic during surgery. -
Ernst von Bergmann
He developed asepsis. He knew from Lister’s and Pasteur’s research that germs caused infections in wounds. He developed a method to keep an area germ-free before and during surgery. This was the beginning of asepsis. -
Robert Koch
He discovered many disease-causing organisms. He developed the culture plate method to identify pathogens and also isolated the bacterium that causes tuberculosis. He also introduced the importance of cleanliness and sanitation in preventing the spread of diseases. -
Paul Ehrlich
He discovered the effect of medicine on disease-causing microorganisms. His treatment was effective against some microorganisms but was not effective in killing other bacteria. His discoveries brought about the use of chemicals to fight disease. -
Wilhelm Roentgen
He discovered x-rays in 1895. He took the very first picture using x-rays of his wife’s hand. He also introduced the importance of cleanliness and sanitation in preventing the spread of disease. -
Anesthesia
Surgery was preformed on patients without anesthesia. Early physicians used herbs, hashish, and alcohol to help relieve the pain of surgery. Then, a drug was invented to have the ability to put people into a deep sleep so they don’t feel anything -

Sigmund Freud
He discovered the conscious and unconscious parts of the mind. He studies the effects of the unconscious mind on the body -
Gerhard Domagk
He discovered sulfonamide compounds. These compounds were the first medications effective in killing bacteria. They changed the practice of medicine by killing deadly diseases. -
Jonas Salk
He discovered that a dead polio virus would cause immunity to poliomyelitis. This virus paralyzed thousands of adults and children every year. It seamed to attack the most active and athletic. -
Albert Sabin
In contrast to Salk’s virus, Albert Sabin used a live polio virus vaccine, which is more effective. This vaccine is used today to immunize babies against this dreaded disease. -
Francis Crick and James Watson
Francis Crick and James Watson discovered the molecular structure of DNA, based on its known double helix. Their model served to explain how DNA replicates and how hereditary information if coded on it. Eventually, they won the Nobel Prize in medicine for this discovery. -
Christian Barnard
He preformed the first successful heart transplant in 1968 -
Ben Carson
He continues to be a pioneer in separating Siamese twins and performing hemispherectomies, surgeries on the brain to stop seizures. -
Period: to
21st century
-
Mobile health
The use of digital information that has rapidly increased this century, -
Wearable technology for healthcare
wearing these devices have been on the rise. Very helpful to track fitness goals, heart rates, and many more information. -
Medication management devices
They play a major role in preventing, diagnosing, treating, and monitoring different medical conditions. -
3D printing in healthcare
This allows for the creation of customized medical devices, implants, and models based on patients specific body functions. This also allows for better surgical planning. -
Electronic health records
They provide an accessible place for patients medical history, improved communication between healthcare providers, and reduced medical errors.
