Final answer:
The question seems to confuse Kappa Sigma with other Greek organizations. Kappa Sigma itself does not have publicly known or easily verifiable honorary members. However, notable figures like Jesse Owens and Duke Ellington are connected with National Pan-Hellenic Council fraternities, and Alpha Kappa Alpha boasts members such as Kamala Harris and Toni Morrison.
Step-by-step explanation:
The honorary member of Kappa Sigma that the question refers to seems to be a mix-up with accomplishments of notable individuals associated with Greek life, more specifically the National Pan-Hellenic Council organizations, not Kappa Sigma. It is worth noting that Kappa Sigma is a different fraternity and their honorary members, if any, are not commonly publicized or verifiable in the context of this question.
However, notable members of other Greek organizations include Jesse Owens and Duke Ellington, who are linked with the National Pan-Hellenic Council fraternities, and remarkable members of Alpha Kappa Alpha sorority include Edwidge Danticat, Kamala Harris, Toni Morrison, Phylicia Rashad, Ellen Johnson Sirleaf, and Wanda Sykes.
