From 1890-1897 Steiner worked at the Goethe-Archive at Weimar. Director was there Bernhard Suphan (1845-1911). In The Story of My Life Steiner writes about him:
When I came to Weimar, and entered into a close relationship with Bernhard Suphan, he was a man sorely tried in his personal life. His first and second wives, who were sisters, he had seen buried at an early age. He lived now with his two children in Weimar, grieving over those who had left him, and not feeling any happiness in life. His sole satisfaction lay in the good will which the Grand-duchess Sophie, his profoundly honoured lady, bore to him. In this respect for her there was nothing servile: Suphan loved and admired the Grand-duchess in an entirely personal way.
In loyal dependence was Suphan devoted to Herman Grimm. He had previously been honoured as a member of the household of Grimm in Berlin, and had breathed with satisfaction the spiritual atmosphere of that home. But there was something in him which prevented him from getting adjusted to life. One could speak freely with him about the highest spiritual matters, yet something bitter would easily come into the conversation, something arising from his experiences. Most of all did this melancholy dominate in his own mind; then he would help himself past these experiences by means of a dry humour. So one could not feel warm in his company. He could in a moment grasp some great idea quite sympathetically, and then, without any transition, fall immediately into the petty and trivial. He always showed good will toward me. In the spiritual interests vital within my own soul he could take no part, and at times treated them from the view-point of his dry humour; but in the direction of my work in the Goethe Institute and in my personal life he felt the warmest interest.
I cannot deny that I was often painfully disturbed by what Suphan did, the way in which he conducted himself in the management of the Institute, and the direction of the editing of Goethe; I never made any secret of this fact. Yet, when I look back upon the years which I passed with him, this is outweighed by a strong inner interest in the fate and the personality of the sorely tried man. He suffered in his life, and he suffered in himself. I saw how in a certain way, with all the good aspects of his character and all his capacities, he sank more and more into a bottomless brooding which rose up in his soul. When the Goethe and Schiller archives were moved to the new building erected in Ilm, Suphan said that he looked upon himself in relation to the opening of this building like one of those human victims who in primitive times were walled up before the doors of sacred buildings to sanctify the thing. He had really come gradually to fancy himself altogether in the role of one sacrificed on behalf of something with which he did not feel that he was wholly united. He felt that he was a beast of burden working at this Goethe task with which others with higher intellectual gifts might have been occupied. In this mood I always found him later whenever I met him after I had left Weimar. He ended his life by suicide in a mood of depression.
