As mentioned earlier here is the 1960 “Time” article about Tom Mboya. On page 8 it mentions the “Jackie Robinson - Harry Belafonte fund” which Mboya oversees and which has already been used to send 81 Kenyans to the U.S. to be educated.
While Susan Mboya has refused to release her father’s papers, some of them may be among the personal papers and correspondence Mboya had with students who participated in the airlift. Those papers are at Stanford and personal correspondence is listed as one of the items in the holdings.
Of interest in the “Time” article, it mentions Pam Odede was sent to Ohio as one of the students. Pam would later become Mboya’s wife and I am sure it is no coincidence that their daughter Susan now lives in Ohio.

Ack -- ten pages that somehow read like they could have been written about Obama's campaign. (Patrice Lamumba worked out well, didn't he?) The reference is on Page 8, for anyone who cares to bypass the propaganda.
If the Boston Globe reported that Susan Mboya "declined to release the letters," wouldn't that indicate that a) the letters is question are not at the Stanford archive; or b) if they are at the Stanford archive, she has right of refusal for release; or c) the letters don't exist. (I choose Door C, Alex.)
Normally, collections stored at University libraries are publicly accessible, but as we learned with the Annenberg Challenge records stored at the UC libary, those rules aren't always followed, particularly if the information pertains to Barack Obama.
