James Benjamin Parker
James Benjamin Parker (July 31, 1857 – ?) was an American most noted for attempting to stop Leon Czolgosz from assassinating president of the United States William McKinley.
Born in Atlanta, Georgia in 1857 to enslaved parents, Parker worked a variety of jobs including as a newspaper salesman for the Southern Recorder and as a constable. He later moved to Chicago, Illinois, where he was employed as a waiter, before returning to Atlanta. This was followed by additional moves to Saratoga, New York, to New York, New York, and, finally, to Buffalo, New York where he took a job with a catering company at the Pan-American Exposition's Plaza Restaurant.
Parker had been laid-off from his job at the Plaza Restaurant prior to September 6, 1901, and used that day to visit the exposition's Hall of Music, where president William McKinley was receiving members of the public.
The recent assassinations of European leaders by anarchists, and often virulent denouncements of McKinley in the newspapers of William Randolph Hearst, combined to concern McKinley's private secretary George B. Cortelyou that there might be an attempt on the president's life. Cortelyou arranged for tight security after the president twice refused to cancel his appearance. A contingent of up to 75 City of Buffalo police and exposition security guards monitored the doors to the Hall of Music and patrolled the queue waiting to see the president. Persons who made it far enough to approach McKinley finally had to pass through a cordon of U.S. Army soldiers who had been instructed to quickly surround anyone who appeared suspicious. Since the Spanish-American War, the United States Secret Service had been protecting McKinley and two special agents, backed by several Buffalo police detectives, stood near the president.
There was, at the time, a general rule that anyone approaching the president must do so with their hands open and empty. However, the heat of the day meant this custom was not being enforced as many people were carrying handkerchiefs with which to wipe away perspiration. A long line of exposition attendees queued to meet the president. The man in front of Parker in the queue, Leon Czolgosz, used the heat to conceal a pistol underneath a handkerchief. As Czolgosz approached McKinley, he fired the weapon twice, hitting the president at point blank range. After the second shot, according to a later account by United States Secret Service special agent Samuel Ireland, Parker punched Czolgosz in the neck then tackled him to the ground. Parker was quickly joined by one of the soldiers and a Buffalo policeman in restraining Czolgosz who was badly pummeled by more soldiers, police, and bystanders before the mortally wounded McKinley could order the beating to stop.
An unnamed witness cited in a Los Angeles Times story said that "with one quick shift of his clenched fist, he [Parker] knocked the pistol from the assassin's hand. With another, he spun the man around like a top and with a third, he broke Czolgosz's nose. A fourth split the assassin's lip and knocked out several teeth."
Despite initial optimism that McKinley would recover, the president died about a week later of complications arising from his wound. Czolgosz was quickly tried and convicted in the Erie County Superior Court and, exactly 45 days after McKinley's death, executed, his body afterwards being dissolved in acid.
