These medical pioneers developed various types of new medical technology.

3. Edward Jenner
Doctor Edward Jenner was the one who helped with the creation of the smallpox vaccine.
Smallpox was a very deadly disease that infected many people throughout the world. He used the virus of a different disease similar to smallpox to create the vaccine.
With his help, smallpox was able to be kept under control. (

4. Joseph Priestly
Joseph Priestly was the person that discovered various gases such as oxygen, nitrous oxide (laughing gas), carbon monoxide, and sulfur dioxide.
Laughing gas is used today to sedate a person during things like surgery, so that they won’t feel any pain.
He also invented soda water, which he hoped would prevent the disease scurvy on long voyages.(historyguide.org)

6. Rene Laennec Rene Laennec was the inventor of the stethoscope
Sometime doctors are unable to feel a patient's heartbeat through his hand or by pressing his ear against the chest due to the patient's "great degree of fatness". 
But with the stethoscope doctors are able to hear a patient’s heartbeat even if the patient has a "great degree of fatness". 
Thanks to his new invention, doctors were able to diagnose various new chest and heart conditions, and he conducted landmark studies on lung,
liver, and skin diseases.  (
