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.
