These World War One Medical Innovations Will Baffle And Amaze You

This year marks the 100th anniversary of the start of World War I, which tore through Europe from 1914 to 1918 and took millions of lives with it. Though most people who would remember the event are gone, the Great War still reverberates through our lives even today. In fact, many life-saving medical innovations that we now take for granted were created during that period by field surgeons and nurses who needed to respond quickly to a number of potentially fatal ailments.

Blood transfusions, which help prevent patients from dying of shock or blood loss, started to be used just before the war. It wasn’t until the the war began, though, that the technique was truly put to the test.

Sepsis, an all-too-common hospital malady back then, was beaten with the invention of antiseptics. And though it sounds obvious to us today, it was also during WWI that practicing good hygiene and cleanliness in hospitals became a prominent strategy for disease prevention. Penicillin wasn’t discovered until 1928, a decade after the armistice that ended the war in 1918. But even without antibiotics, WWI surgeons brought us out of medicine’s dark ages.

One of the terrible realities of life as a soldier in the Great War was gas: mustard, chlorine, and phosgene. As you might expect, the gas mask was invented during WWI to counter the toxins’ potentially fatal effects. An early version can be seen on both soldiers and war horses in this photo.

If you want to learn about what being gassed felt like, watch as Jake Gyllenhaal reads a poem about it by soldier poet Wilfred Owen. “Dulce et decorum Est” is perhaps the best-known poem from the war. When translated from Latin, the full phrase appearing in the poem means “It is sweet and right to die for your country.”


In the last year of the war, the Spanish Flu pandemic hit. Hard. It killed 50 million people worldwide in just a few years, even before the growing number of scientific innovations that had previously saved thousands of lives. That’s more deaths than the entirety of WWI, which clocked in at 35 million.
