Please answer the following question: What is the name of the man that gives Solomon Northup a violin?  Answer the above question based on the context below:  In 1841, Solomon Northup is a free African-American man working as a violinist, living with his wife and two children in Saratoga Springs, New York. Two white men, Brown and Hamilton, offer him short-term employment as a musician if he will travel with them to Washington, D.C. However, once they arrive they drug Northup and deliver him to a slave pen run by a man named Burch. Northup proclaims that he is a free man, only to be savagely beaten with a wooden paddle and then a leather belt. Northup is later shipped to New Orleans along with other captive African Americans. He is told by the others that if he wants to survive in the South, he must adapt to being a slave and not tell anyone he is a free man. A slave trader named Theophilus Freeman gives Northup the identity of "Platt", a runaway slave from Georgia, and sells him to plantation owner William Ford. Ford takes a liking to Northup and gives him a violin. However, tension grows between Northup and plantation carpenter John Tibeats which ends with Northup savagely beating and whipping Tibeats. Tibeats and his group try to hang Northup. Although they are not successful, Northup is left on the noose for hours before he is finally cut down. To save Northup's life, Ford sells him to another slave owner named Edwin Epps. In the process, Northup attempts to explain that he is actually a free man, but Ford tells him he is too afraid and that he cannot help him now.
A:
William Ford
