Former U.S. President Theodore Roosevelt was shot and wounded by a .38 caliber bullet fired by John Schrank, a New York City saloonkeeper, who was standing at a distance of only 30 feet. The bullet was slowed when it passed through Roosevelt's metal eyeglasses case and the folded, fifty-page manuscript of Roosevelt's prepared speech, but still penetrated three inches into his chest, too close to the heart to be safely removed by surgery. Schrank was tackled by bystanders before he could fire a second shot, and Roosevelt went on to deliver his speech before getting medical treatment. Schrank would be found insane and would spend the rest of his life at a mental hospital in Waupun, Wisconsin, where he would die on September 15, 1943.

The Ottoman Empire (Turkey) and Italy signed the First Treaty of Lausanne at the Swiss city of Ouchy at 3:30 pm to end the Italo-Turkish War, with Turkey agreeing to grant independence to Tripolitania and Cyrenaica long enough for the North African provinces to come under Italian control.

The Ottoman field commanders were ordered to withdraw their men, despite their feeling that they "were more than sure of their ability to win the war", and transferred Libyan soldiers to Istanbul for military training and an eventual recapture of the territory, a plan which would fail during the First World War.
