Harrisburg Cemetery holds the remains of many famous Pennsylvanians, including those who contributed to the Commonwealth's and the Union's military and anti-slavery efforts prior to, and during, the Civil War. Union and Confederate soldiers wounded in the Battle of Gettysburg, and who later died in Harrisburg hospitals, are interred here.
The statue and grave of Major General John White Geary (1819-1873), who served as Mayor of San Francisco and Governor of both the Kansas Territory and Pennsylvania, is also buried here. During the War, he served with distinction during the Chancellorsville, Gettysburg, and Atlanta campaigns.
Harrisburg lawyer and judge Mordecai McKinney (1796-1867), who helped lead the way through adversity in defending local African Americans and freedom seekers from the South, is also interred here. Born into a slaveholding family, McKinney became a fervent abolitionist who tirelessly worked to improve the cultural life of the African American community in Harrisburg by helping to found the African American Second Presbyterian Church.
Brigadier General Joseph F. Knipe (1824-1901), in charge of the Union's defense of Harrisburg when threatened by Confederate forces in June 1863, also lies here, as does Simon Cameron (1799-1889), Abraham Lincoln's first secretary of war and longtime U.S. senator.
