Army Medical School
A British Bacteriologist named Almroth Edward Wright developed the typhoid vaccine at the Army Medical School in 1896. Many of his peers in the army were wary of his discovery, and refused to let their troops get immunized during the South African war, resulting in over 8,000 British troops dying from typhoid. Because of this, vaccinations were allowed and encouraged when the British entered the first World War. This resulted in the first war where the death from combat outnumbered deaths from typhoid.
Assassination Attempts in Constitution Hill
The road Constitution Hill in London, England, is close to the Buckingham Palace Gardens. Queen Victoria and Prince Albert would often ride through it in a carriage. Three of the seven assassination attempts against Victoria occurred here: Edward Oxford, John Francis, and William Hamilton shot at Queen Victoria in her carriage in 1840, 1842, and 1849, respectively. They all occurred very similarly, with each man firing at her carriage, failing to injure her or anyone else, and then getting swiftly captured and incarcerated afterward.
