Ancient Romans
The Romans had invented a sanitation system. The system brought clean water to their villages by waterways. This kept their water more sanitary and led to less diseases. The Romans were the first to organize their medical care. They sent equipment and doctors to care for the soldiers in the army. The Roman doctors would keep the ill in rooms in their houses. This began the idea of hospitals. -

500
The study of medicine stopped
In when the Huns took over the Roman Empire, they had stopped studying medical science. For roughly 1,000 years, medicine was only done in convents and monasteries. This was because the Church believed that life and death was under control by God. The monks and priests didn’t care about how the body functioned. -

Epidemics
During the Middle Ages, horrible epidemics occurred resulting in millions of deaths. The Bubonic plague caused 60 million deaths alone. Other diseases such as the small pox, diphtheria, syphilis, and tuberculosis were life threatening during these times. -
Period: 1350 to
The Renaissance
-
1450
Rebirth during the Renaissance
The Renaissance viewed the rebirth as learning. During the Renaissance, new scientific knowledge began. Some of the things that were developed during this period was, the building of medical schools and research, new ideas involving disease rather than thinking disease was the will of God, accepting dissection to study the body, and developing the printing press for publishing books. -

1563
Bartolommeo Eustachio
Bartolommeo Eustachio discovered the Eustachian tube which leads from our ears to our throat. -
William Harvey
William Harvey used the Leonardo’s deception of the human body to understand physiology. William Harvey was able to narrate the circulation of blood and the pumping of the heart. -
Antonie von Leeuwenhoek
Antonie van Leeuwenhoek created the microscope, realizing that their is life that the human eye can’t see. Antonie van Leeuwenhoek discovered bacteria from scraping his teeth causing tooth decay, -

Benjamin Franklin
Benjamin Franklin discovered bifocals. He also found out that colds could be transmitted from person to person. -
Medical students learning
Multiple discoveries were made during the eighteenth century. Medical students attended classes in classrooms, laboratory, and patients at bedside. When someone had passed away the students would dissect the body and observed it. This helped them better understand why illness and death occurred. -
Joseph Priestley
Joseph Priestley discovered the elements of oxygen. Joseph Priestley also observed that plants refresh air that has lost its oxygen. He determined that it is used for respiration. -
Edward Jenner
Edward Jenner discovered methods of vaccinations for the smallpox. Smallpox had killed a ton of people. Edwards discovery prevented millions of deaths from the disease. This also led to immunization and preventive medicine in public health. -
René Laënnec
René Laënnec invented the stethoscope. The stethoscope was made entirely out of wood. It allowed them to hear the heart and lungs. The stethoscope allowed doctors to determine if diseases were present. -
Period: to
19th and 20th Centuries
-
Ignaz Semmelweis
Ignaz Semmelweis identified why childbed fever occurred. Many women had died from childbed fever after giving birth. Ignaz Semmelweis had figured out that patients of midwives that had given birth had fewer deaths percentages. This was because care given by physicians were not as sanitary. Physicians would not wash their hands after dissecting dead bodies before delivering babies. Due to his discovery hand washing and cleanliness became an essential practice. -
Florence Nightingale
Florence Nightingale was the founder of modern nursing. Before this time, women were unsuitable ti be a nurse. She took 38 women to care for soldiers who were dying from cholera in the war. She soon became a hero while she was there. After the war, she decided to devote her life to sanitation and construction management of hospitals. She designed clean environments for patients. These environments consisted of limited numbers of beds, air circulation, windows, and that the rooms were clean. -
Louis Pasteur
Louis Pasteur also knows as the “Father of Microbiology”, came upon that tiny microorganisms were everywhere. Throughout his experiments, he determined that microorganisms caused diseases. Before he determined that, doctors and scientists had thought that microorganisms were created by diseases. In addition, he had discovered that pasteurization killed bacteria in milk. We still use this method to this day. Louis also created a vaccine for rabies in 1885. -
Dmitri Ivanovski
Dmitri Ivanovski figured out that some diseases were caused by microorganisms that couldn’t be examined through a microscope. These microorganisms are referred to as viruses. The viruses were not examined until the electron microscope was created in Germany. Some examples of diseases caused by viruses are: rabies, mumps, influenza, measles, poliomyelitis, German measles, herpes zoster, and the chicken pox. -
Joseph Lister
Joseph Lister had studied Pasteurs discovery that microorganisms caused infection. He used carbolic acid on cuts to kill germs that caused infections. Lister became the first doctor to use antiseptic during surgery. Antiseptics help prevent infections in incisions. -
Ernst von Bergmann
Ernst von Bergmann developed asepsis. He used his knowledge from Lister’s and Pasteur’s discoveries that germs caused infections in wounds. Ernst developed a method to keep areas germ-free before and after procedures. -
Robert Koch
Robert Koch discovered many disease- causing organisms. Robert made the culture plate method to help name pathogens and isolated bacterium that resulted in tuberculosis. Robert also found the importance of cleanliness to help stop the spread of disease. -
Paul Ehrlich
Paul Ehrlich determined the effect on medicine on disease causing microorganisms. The treatment he had discovered worked against some microorganisms but didn’t kill other bacteria. Ehrlich discoveries brought the idea of use of chemicals to kill diseases. While he was trying to find a chemical to cure syphilis, he tried 606 different experiments. He finally found a treatment that was effective. -
Wilhelm Roentgen
Wilhelm Roentgen discovered x-rays. He was the first to take x-ray pictures of his wife’s hand. This discovery let doctors see inside the body and helped them figure out what was wrong. -
Anesthesia
Before anesthesia was invented, surgeries were performed without any. They used herbs, hashish, and alcohol to help decrease pain. Sometimes they chicken patients to make them unconscious. Many deaths occurred due to pain from surgeries and procedures. During the nineteenth and twentieth century, nitrous oxide was invented. This allowed patients to be put into a deep unconscious so they wouldn’t experience any pain. -
Sir Alexander Fleming
Sir Alexander Fleming discovered that penicillin killed deadly bacteria. This discovery is known as one of the most important discoveries of the twentieth century. Before penicillin was found, people died from illness that are now treatable today. -
Sigmund Freud
Sigmund Freud was the first to discover conscience and unconscious parts of the mind. He gathered information about the effects of the unconscious mind on the body. He had realized that the mind and body worked together. This led to the understanding of psychomatic illness. -
Gerhard Domagk
Gerhard Domagk discovered sulfonamide compounds. These were the first medications that killed bacteria. These compounds helped change the practice of killing life threatening diseases. -
Jonas Salk
Jonas Salk came across that dead polio virus would cause immunity to poliomyelitis. This viruses thousands many people each year. Active people were known to develop this virus. The discovery of the vaccine allowed many people to survive the virus. -
Albert Sabin
Albert Sabin used living polio in the vaccine. This was more effective than dead polio. This vaccine is still used to this day to immunize newborns against this disease. -
Francis Crick and James Watson
Francis Crick and James Watson were the first to discover the molecular structure of DNA, based on its double helix. The model they had created explained how DNA replicates and how hereditary information was passed on. This was the beginning of advanced information on molecular biology. In addition, Francis Crick and James Watson won the Nobel Prize in Medicine from this discovery. -
Christian Barnard
Christian Barnard accomplished the first successful heart transplant. -
Ben Carson

Advancements in medicines
Five advances that I believe are very important in the twenty first century are, Covid-19 testing, cancer therapy such as chemotherapy, and radiation, pain killers, and antibiotics, imagining such as MRI and CT scans. Without these advances we wouldn’t be where we are today with medicine.
