Clayton Kirk Slack (February 23, 1896 – March 1, 1976) was a soldier in the United States Army
 who received the Medal of Honor for his actions during the World War I.

Slack was born in Plover, Wisconsin on February 23, 1896.[1]
Clayton Slack joined the United States Army and as a Private during World War I he was cited for single-handedly clearing out a German machine gun nest resulting in 10 prisoners and the capture of 2 machine-guns on October 8, 1918, in the Meuse-Argonne offensive, the biggest battle of World War I involving American troops.[1]
Slack noticed several German troops and charged at them with his rifle and bayonet telling them to “put their hands up”.[1] The German soldiers thinking that he was at the lead of a patrol, surrendered. Slacks actions were credited with saving his unit heavy casualties.[1]
After the war Slack toured the United States with war films and by the time of his death had met six presidents. In 1963 presidentJohn F Kennedy hosted a reunion of Medal of Honor recipients at the White House for the 100th anniversary of the first presentation of the Medal.[1] Slack attended the function along with a number of other Medal of Honor recipients.[1]
He died March 1, 1976 and is buried in Arlington National Cemetery Arlington, Virginia.[1] His grave can be found in section 34, lot 59.[1]
