Is the Sacred Order of Skull and Crescent connected to Phi Kappa Psi?

No. Some say that Purdue's society is connected for two reasons: Phi Kappa Psi has a "fraternity within a fraternity" called the Order of S.C., started in 1920, and the meaning of S. and C. is kept secret. Some say that it stands for "skull and crescent", but that has never been shown to be the case. The other reason is that Purdue's Sacred Order of Skull and Crescent did visit an East Coast chapter of Phi Kappa Psi during their 1882 tour. A picture of Purdue's society with its 15 members and its symbols of the skull & cross bones and the great horned owl was taken under a Phi Kappa Psi backdrop, but that was only to commemorate their tour. Some confuse that photo as Phi Kappa Psi members, or that Phi Kappa Psi had a chapter of the Sacred Order of Skull and Crescent. The Sacred Order of Skull and Crescent is only connected to Yale's Skull and Bones society, and to certain members of Alpha Delta Phi when Chase connected Skull and Bones members of Alpha Delta Phi to Purdue's society.
