The first Secret Service operative to die on duty was William Craig (left, boarding carriage), a 6-foot-4 former member of the British military who served as President Theodore Roosevelt's personal bodyguard. On September 3, 1902, while on a trip in Pittsfield, Mass., the president's open carriage was struck by a speeding trolley car. The president was thrown clear of the wreck, only suffering bruises. Craig, however, was killed.
Though he died in an accident, Craig was aware of other dangers posed to himself and the man he guarded. "The danger lies in some fanatic getting up to the president and shooting or stabbing so quietly that it cannot be prevented," he told the Worcester Telegram shortly before he was killed. "If no outsiders are allowed within 10 feet of the president - and 25 feet is still better - the danger is greatly lessened."
He added that whenever he was standing close to the president, he kept his hand in his coat, holding his revolver, ready to fire at any moment.
