"But with your loss, oh Karl Heinrich Ulrichs, the fame of your works and your virtue will not likewise disappear...but rather, as long as intelligence, virtue, learning, insight, poetry and science are cultivated on this earth and survive the weakness of our bodies, as long as the noble prominence of genius and knowledge are rewarded, we and those who come after us will shed tears and scatter flowers on your venerated grave."
