1842 The first surgical anesthetic use of ether is credited to Dr. Crawford Williamson Long, MD, age 27, of Jefferson, Georgia. On March 30, 1842, he removed one of the two tumors from the neck of Mr. James Venable under ether anesthesia. Apparently, he had used ether for minor surgery as early as 1841, and had originally learned about ether during "ether frolics" while in medical school at the University of Pennsylvania.

1845 The Hypodermic syringe was invented in the mid nineteenth century. In 1845 Francis Rynd, an Irish physician, developed the hypodermic needle. Six years later Tabourin, a French veterinarian, made various improvements to the syringe. The invention of the hypodermic syringe, however, is largely attributed to Alexander Wood, a Scottish physician from Edinburgh.
The hypodermic syringe significantly added to the tools available to the veterinary surgeon, it's earliest use was for the injection of morphine, used as an anaesthetic in surgery.

1803 US purchases the Louisiana Territory from Napoleon mostly because French troops are decimated by Yellow Fever in Haiti
Here's a summary of the story; Late in 1801, Napoleon sent his brother-in-law, General Victor-Emmanuel LeClerc and 20,000 troops to seize the entire island and put an end to the slave turned rebel leader of the island, known as the "pretender", L'Ouverture.
LeClerc and his troops landed at Cap Francais on 29 January 1802. The French forces under LeClerc were the most capable the rebels had yet faced. And after a few short, bloody battles, the French essentially controlled the island. LeClerc was certain that total victory would soon be complete.
But LeClerc was troubled because many of his soldiers were becoming sick with a high fever. He expressed his concern to Napoleon, writing, "I have 600 men on my sick list." A week later, he noted, "I have already 1,200 in hospital." . It would only get worse. In late March, LeClerc was still fighting rebel forces. And in April the rains came, and with the rains came yellow fever.

1809: Scottish anatomist Allan Burns demonstrates the association of high blood pressure with angina (chest pain) and sudden death due to heart attacks (which had previously been attributed to "acts of God")
The demonstration is still valid today: put a tourniquet on your bicep and then exercise the arm. It won't be long until extreme fatigue and pain sets in and the arm goes limp. Remove the tourniquet and soon all is well. This mimics what happens to the heart if coronary arteries (arteries supplying the heart with blood and nutrients) are restricted due to clogging (the most common form of severe heart disease today)

1816: French physician Rene Laennec devises the stethoscope which magnifies the cardiac sounds allowing us to detect murmers and valvular diseases. Midwifes were using something similar to a stethoscope to listen for the presence of a fetal heart beat, so I'm reluctant to give Dr Laennec too much credit for his "invention", but the interesting thing about the stethoscope is that he apparently devised it to keep from putting his ear up against the bosom of his female patients, which he thought improper! (No wonder it took so long to invent the thing)
Note: the above story about Dr Rene Laennec may not be 100% accurate. Other related stories indicate that the good doctor may have been telling a white lie to be polite; maybe he was a fussy sort of person and didn't want to get too close to patients who stunk. Or maybe he had an inkling that physicians that got too close to sick patients might also get the disease. And maybe he shouldn't get too much credit at all; midwives had been using a similar cone device for centuries to listen to fetal heartbeats
