William McKinley (allthetropes.org)
William McKinley is mainly known nowadays as the President whose assassination resulted in the much-better-known Theodore Roosevelt coming into office. He is also one of the more famous victims of violence perpetrated in the name of Anarchism; a few short but eventful decades later, the radicals to really be afraid of would be communists instead. Much like James Garfield before him, technology was right there that probably would have saved him, but several decisions surrounding the operation didn’t work out for keeping him alive (the new “x-ray machine” being exhibited at the very expo where he was shot was too untested for doctors to trust it, and apparently they didn’t think to do the surgery under the brand-new electric lighting, nor could they use candles because ether was still the best anesthetic available at the time). Similarly, his assassination receives little attention in public memory compared to that of Abraham Lincoln or John F. Kennedy, despite serving longer than the latter.- William McKinley (Wikipedia)
William McKinley (January 29, 1843 – September 14, 1901) was an American politician who served as the 25th president of the United States from 1897 until his assassination in 1901. A member of the Republican Party, he led a realignment that made Republicans largely dominant in the industrial states and nationwide for decades. He presided over victory in the Spanish–American War of 1898; gained control of Hawaii, Puerto Rico, Guam, and the Philippines; restored prosperity after a deep depression; rejected the inflationary monetary policy of free silver, keeping the nation on the gold standard; and raised protective tariffs.
