The following are installments of The Omega Minute videos which highlight an aspect of the history of the Fraternity. These three involve the genesis and development of the Memorial Service, which is one of the Fraternity's mandated programs.
As stated in the videos, in The Ritual there are two types of Memorial Services: 1) the Annual Memorial Service which each chapter is mandated to hold in March (which is subdivided between the Forman Memorial Service and the Informal Memorial Service) and 2) the Memorial Funeral Service for deceased Brothers.
