the begin and end dates represent when an individual first joined (typically corresponding to an ordination date) and last belonged to the quorum. strictly speaking, members of the first presidency rejoin the quorum temporarily when a church president dies, and before a successor is named. for simplicity, this list does not consider these periods in determining the end date. on occasion, a quorum member has left the quorum for a time and later rejoined it; this is noted where applicable.
