Final answer:
The founding members of Sigma Chi were originally part of Delta Kappa Epsilon and were in conflict over voting practices that led to the formation of Sigma Chi in 1855. The specific issue with a dinner meeting is not well-documented in the provided reference and seems to be unrelated to the founding context of Sigma Chi.
Step-by-step explanation:
The Sigma Chi fraternity was founded at Miami University in 1855, in a conflict concerning the principles of brotherhood, fairness, and the freedom of members to vote their consciousness. The dispute arose when several members of the Delta Kappa Epsilon (DKE) fraternity at Miami University were compelled to vote for certain candidates at a college poetry contest. The founders of Sigma Chi, originally members of DKE, found this inconsistent with the values of true friendship and justice, leading to a rift and the subsequent establishment of Sigma Chi.
The actual issue or incident mentioned in your question, referring to those founders inviting their DKE brothers to a dinner meeting, is not well documented in the provided reference (Lawrence Ross, The Divine Nine: The History of African American Fraternities and Sororities). It seems there might be a conflation with a different event or historical narrative. The passage you provided from a book regarding a dinner scene with characters 'Marcus', 'Mr. Sieppe', 'Old Grannis', 'Miss Baker', 'Uncle Oelbermann', 'Heise', and 'Owgooste' refers to a different context, presumably from a novel, that does not align with the founding of Sigma Chi. Hence, it does not provide information regarding the dinner meeting in question. For accurate historical perspective on the founding issue, separate research about Sigma Chi's early history would be more appropriate.
