The discovery of the date of Locke’s conversion does not throw any light on the next two years of Locke’s activities as a Bahá’í. It was the usual practice at that time for new believers to write to ‘Abdu’l-Bahá in the Holy Land. Indeed, there is indirect evidence that Locke, following his conversion, did write to ‘Abdu’l-Bahá in Haifa. That same evidence directly points to the existence of a Tablet that ‘Abdu’l-Bahá revealed in reply. Such evidence rests on the testimony of Louis Gregory who, in 1933, wrote: “It is to be hoped that the friends both locally and nationally, will largely make use of the great powers of Dr. Locke both in the teaching and administrative fields of the Cause. He has made the pilgrimage to Haifa. The Master in a Tablet praised him highly and it is known that the Guardian shares his love for our able brother." This “lead” was the clue that launched my quest to find that missing Tablet. In the Alain Locke Papers, I did discover a Tablet, dated 1919, from ‘Abdu’l-Bahá, but its recipient was someone other than Locke himself. To date, the Tablet to Locke has not been found.

Update, 2014: Please see p. 31 of the Bahá'í Studies Review article for the original Persian text of the Tablet by Abdu’l-Baha mentioning Locke. Translation of comment regarding Locke:

Figure 1: Facsimile of Tablet of ‘Abdu’l-Baha to to Mrs Agnes Parsons, July 26, 1921 in which he writes concerning Locke, "His honor, Dr Locke – this distinguished person deserves every consideration for him from the Divine Kingdom."
