1912 Yes, the Grossest Schiff in the Welt. The same size as the Titanic - well, a few feet more. Wikipedia:

On her first arrival the harbour pilot assigned to bring her into the Ambrose channel, Captain George Seeth, noted that the ship listed from side to side when the helm made changes to the ship's direction. She was soon nicknamed "Limperator".

The indignities mounted: when war broke out the ship was moored in Hamburg, and sat there doing nothing until the war was over. Since the war was also lost, the Allies said thank you very much where'd you put the keys? and that was that for the Imperator.

The name, that is. As for the ship . . .
