Less than three weeks after Brigham Young died in 1877, Wilford Woodruff stood in the Tabernacle in Salt Lake City and delivered an address that was mostly sermon, part eulogy. He ended it by speaking at length about the doctrine of temple work:
Before I close, I want to say one thing to the Latter-day Saints, which is resting upon my mind. President Young having now passed away, his labors with us have ceased for the present. He, with his brethren, built and completed one Temple, also laid the foundation for one at Manti and one at Logan, and besides a great deal of work has been done on the one in this city. He left this unfinished work for us to carry on to completion; and it is our duty to rise up and build these Temples. I look upon this portion of our ministry as a mission of as much importance as preaching to the living; the dead will hear the voice of the servants of God in the spirit world, and they cannot come forth in the morning of the resurrection, unless certain ordinances are performed, for and in their behalf, in Temples built to the name of God.
Members of the church did ordinance work in the Endowment House in Salt Lake City starting in 1855, but as Brigham Young explained in 1874,
We can, at the present time, go into the Endowment House and be baptized for the dead, receive our washings and anointing, etc. … We also have the privilege of sealing women to men, … in the Endowment House; but [other ordinances] … cannot be done without a Temple.

As I turned the pages of Der Stern (1917), the publication of the Swiss-German Mission, I was rather startled to see an Iron Cross. To my eye, the Iron Cross is an enemy symbol, something akin to a swastika. Then I noticed the text accompanying the Cross: “Ehre ihrem Andenken,” literally, “Honor to their Memory” or as translated here, “In Memoriam.” The black-bordered notice listed three recent war deaths, all of them young men of mission age, two from the Chemnitz Branch and one from Hamburg.
