Whitman died on March 26, 1892. An autopsy revealed his lungs had diminished to one-eighth their normal breathing capacity, a result of bronchial pneumonia, and that an egg-sized abscess on his chest had eroded one of his ribs. The cause of death was officially listed as "pleurisy of the left side, consumption of the right lung, general miliary tuberculosis and parenchymatous nephritis". A public viewing of his body was held at his Camden home; over 1,000 people visited in three hours. Whitman's oak coffin was barely visible because of all the flowers and wreaths left for him. Four days after his death, he was buried in his tomb at Harleigh Cemetery in Camden. Another public ceremony was held at the cemetery, with friends giving speeches, live music, and refreshments. Whitman's friend, the orator Robert Ingersoll, delivered the eulogy. Later, the remains of Whitman's parents and two of his brothers and their families were moved to the mausoleum.
