The Great War in Europe was viewed in the United States in 1914 as a catastrophe, a tragedy, and wholly unnecessary. There were speculations that perhaps it was the inevitable result of forsaking the sensible conduct of business in pursuit of militarism. But by 1917 the mood in the U.S. had changed.

A steady drumbeat of news accounts tinged with anti-German sentiment played on public perception. The Germans tried to claim military necessity to excuse their use of force as an invading and occupying army in France and Belgium. But too many dead civilians and destroyed towns led to commentary in these pages that Germany was guilty of “barbarity,” “piracy” and being run by a “power-mad autocracy.”

The most direct reason for the U.S. entry into the war was submarine warfare by Germany, according to frequent editorials in Scientific American. Submarines were a relatively new weapon when war broke out in 1914. They were envisaged originally as weapons for attacking ships in harbors and defending coastlines from enemy fleets. But during the war the Germans developed the strategy of attacking trans-oceanic trade itself. Historians generally support the idea that Germany gambled and lost: its leaders believed they could manufacture and deploy enough advanced submarines to shut down trans-Atlantic trade and starve England, France and Italy into submission before the industrial and military might of the U.S. could be brought to bear in Europe. But the Americans were furious when their civilian ships, such as the Lusitania, were destroyed and their citizens killed.

When Germany announced in January 1917 that it would resume unrestricted submarine warfare, an editorial in Scientific American flatly stated: “The United States has been brought as close to the possibility of war with Germany as the eyelid is to the eyeball” [Scientific American, February 10, 1917]. Three weeks later, another editorial responded to the renewed nautical carnage by stating: “We are embarked in the Great European War. Of that there can be no doubt whatsoever. Our entrance into the conflict took place on that fateful day, the 17th of March, when three of our peaceful and unarmed merchantmen were sent to the bottom ... by German lawlessness and brutality” [Scientific American, March 31, 1917].

On April 2, the formerly noninterventionist President Woodrow Wilson addressed a joint session of Congress, asking for a declaration of war. His eloquent speech [published in Scientific American, April 14, 1917 as “The President’s War Message”] emphasized morality, “calling upon the country to wage war in defense of those great principles which are the foundation of all true democracy.” By April 6th the Senate and House of Representatives voted to support Wilson’s call, and the U.S. was at war with Germany.

Scientific American was a witness and commentator on what has been called “the first science war.” Our Archive covers how science and technology entered and was used in the war from 1914 to 1918, but also looks at how the war affected individuals, and analyzes the news from the home front. Perhaps most telling, from our view in 2017, we can explore the news and perspectives on the war at the time, and see where these were either accurate, misleading, or just plain wrong.

There is a rich variety of material in the Archive available to the interested reader. Here is a sampling of some themes and ideas:
