Joseph Hannen records: “On Tuesday, April 23rd, at noon, ‘Abdu’l-Bahá addressed the student-body of more than 1,000, the faculty and a large number of distinguished guests, at Howard University. This was a most notable occasion, and here, as everywhere when both white and colored people were present, ‘Abdu’l-Bahá seemed happiest. The address was received with breathless attention by the vast audience, and was followed by a positive ovation and a recall.”
