Final answer:
The original founder of Kappa Sigma was Manuel Chrysoloras, who inspired the fraternity's values during his time at the University of Bologna. William Grigsby McCormick is regarded as one of the founding fathers of the American chapter, which was established at the University of Virginia in 1869.
Step-by-step explanation:
The original founder of Kappa Sigma is b) Manuel Chrysoloras. Kappa Sigma, also known as Kappa Sig, is one of the largest international fraternities with chapters at colleges and universities across the globe. Manuel Chrysoloras was a Greek scholar who taught at the University of Bologna and is credited with inspiring the values and traditions of the fraternity. The group that eventually became Kappa Sigma was formed for mutual protection against Baldassare Cossa, who later became Antipope John XXIII, during Chrysoloras's time at the university. However, the American founding is often credited to William Grigsby McCormick, who is considered one of the founding fathers, along with four other students at the University of Virginia in 1869.
