Long ailing, Charles Sumner died of a heart attack at his home in Washington, D.C., on March 11, 1874, aged 63. He lay in state at the United States Capitol rotunda, the second senator (Henry Clay being the first, in 1852) and fourth person so honored. At his March 16 burial in Mount Auburn Cemetery in Cambridge, Massachusetts, the pallbearers included Henry Wadsworth Longfellow, Oliver Wendell Holmes, Ralph Waldo Emerson, and John Greenleaf Whittier. In the aftermath, Mississippi Senator Lucius Lamar's eulogy for Sumner was controversial enough considering his Southern heritage that the incident resulted in Lamar's inclusion in John F. Kennedy's book Profiles in Courage. His final illness came while he was still a United States senator, after years in which poor health had repeatedly interrupted his work. The injuries inflicted during the caning in the Senate in 1856 were an important earlier episode, but should not be confused with the reported heart attack of 1874. In his last political period he continued to press for equal civil rights. The civil rights legislation associated with that campaign passed after his death, making his final public efforts unfinished work rather than an accomplished settlement he lived to see.
