Task: Question Answering
Input (English): Passage: In December 1775, Cletus Moyer is a free black Northerner in colonial America, working with a pre-Underground Railroad network to help slaves escape captivity. In the days just prior to Christmas, a group of bounty hunters led by Hattie Carraway captures Moyer near the Parker plantation in Spotsylvania County, Virginia. Because of his capture, dozens of slaves who have already left their plantations in escape attempts are in danger of being captured as well. Moyer implores two slaves from the nearby Reynolds plantation to take his place: Kunta Kinte, a Mandinka in his mid-twenties who was captured in what is now the Gambia, and Fiddler, an elderly man who was born into slavery. Kunta is eager to help (and to escape himself), but Fiddler is unwilling, fearful of the consequences if they are caught.
After an unsuccessful slave revolt elsewhere in the colony, Moyer and two slaves are hanged by Carraway's men on Christmas Eve, prompting Fiddler to set aside his fear and help Kunta lead the runaway slaves to freedom. Although the pair successfully leads the runaways that night to their next stop on the escape route (a boat waiting at the river) there is only room for one of them, and since neither one wants to go without the other, they both decide to stay.  That choice forces them to return to the Parker plantation and manufacture an excuse for their temporary absence. Nevertheless, Kunta and Fiddler are left with the satisfaction of knowing that they helped to give a group of fellow slaves the best Christmas gift of all: freedom. 
Question: What's the last name of the one responsible for involving Kunta and Fiddler in freeing slaves?
Output (English): Moyer.
