Janet Ruhe-Schoenin in Champions of Oneness: Louis Gregory and His Shining Circle p77, noted that ‘Abdu’l-Bahá recognized race amity matriarch Mrs. Amalie Knobloch and revealed a Tablet to be read when visiting her grave:

He is God! O, thou Pure Spirit, Amalie Knobloch! Although thou didst soar away from this terrestrial world, yet thou didst enter into the immeasurable, illumined Universe of the Almighty. While in this life thou didst hear the Divine Call, beheld the light of Truth, became alive by the Breaths of the Holy Spirit, tasted the sweetness of the Love of God, became the Maid-Servant of the Lord of Hosts and the object of the Bounties of His Highness the Desired one. Thou didst lead the erring ones into the Path of Truth and bestowed a portion of the Heavenly Food to those who are deprived. Thou didst consecrate the days of thy existence to the Service of His Highness the Clement and spent thy time in the diffusion of the Fragrances of the Paradise of Abha. There are many souls perfumed and many spirits illumined through thy services!

O, thou divine, beloved Maid-Servant! Although thou didst disappear from the mortal eyes, yet thou didst train and educate thy daughters, each of whom has arisen to serve the Kingdom like unto thee and is engaged in the guidance of the souls. In the Assembly of wisdom they are the lighted candles; they sacrifice their lives in the Path of God; they are gardening in thy orchard and irrigating thy rose-garden. Happy is thy condition, for thou art enjoying Eternal Life in the Kingdom of Everlasting Glory and hast left in this world kind and loving Remembrances. Happy are those souls who visit thy luminous resting-place and through thy commemoration receive and acquire spiritual Powers!

See Aflame with Devotion Chapter 9, "Loss of a Matriarch" pp99-109 for moving description of the passing a believer that was so beloved of Àbdu'l-Bahá.

After a stay of three weeks she travelled to Wiesbaden in Germany to visit a contact and spent five days at the home of the Schweitzers in Suffenhausen.

Some goals were:
  - To double the number of Local Spiritual Assemblies from fourteen to twenty-eight, increasing the Bahá’í membership in each community
  - To raise the number of localities in Germany and Austria where Bahá’ís reside
  - To deepen the understanding of the friends in the operation of the Administrative Order
  - To encourage deeper study of the teachings
  - To construct the National Hazíratu’l-Quds in Frankfurt
  - To enrich Bahá’í literature with two publications by March 1949, fifteen by March 1950, six by March 1951 and nine by 1952

He is Particularly anxious to have some of the German Bahá'ís enter the western territories of the Soviet Union not yet open to the Faith, namely: Estonia, Lithuania, Latvia, Ukraine, White Russia and Moldavia, and every effort should be made to enable some of the Bahá'ís, German or of other nationality, to go to these countries. The young people in particular may be able to arrange their affairs in such a way as to procure employment in the Soviet Union. This would be a great service, and is part of the work allotted to the German Bahá'ís under the World Crusade. [14 August 1953]

The five-fold purpose of the International Conferences was:

1. offering humble thanksgiving to the Divine Author of our Faith, Who has graciously enabled His followers, during a period of deepening anxiety and amidst the confusion and uncertainties of a critical phase in the fortunes of mankind,
2. to prosecute uninterruptedly the Ten-Year Plan formulated for the execution of the Grand Design conceived by 'Abdu'l-Bahá,
3. of reviewing and celebrating the series of signal victories won so rapidly in the course of each of the campaigns of this world-encircling Crusade,
4. of deliberating on ways and means that will insure its triumphant consummation,
5. and of lending simultaneously a powerful impetus, the world over, to the vital process of individual conversion -the preeminent purpose underlying the Plan in all its ramifications - and to the construction and completion of the three Mother Temples to be built in the European, the African, and Australian continents.

The announcement stunned the journalists at the press conference, who greeted it with first disbelief and then elation. The news spread like wildfire and within hours, thousands of East Germans began flocking to the checkpoints along the wall.

They were met by bewildered border guards, struggling to understand what their instructions were regarding this new policy. At around 22:45, overwhelmed by the sheer number of people arriving and lacking any clear orders, the border guards finally opened the gates and overjoyed East Germans flowed over into West Berlin.

"...he poured out his life in uninterrupted service to the Cause of Bahá’u’lláh, as a teacher, pioneer, and member of the National Spiritual Assemblies of Germany (1963-1969) and Finland (1977-1980), the Continental Board of Counsellors in Europe, (1980-1988) the International Teaching Centre (1988-2003) and, ultimately, of the Universal House of Justice (2003-2008)."
