Bolton's glowing recommendations failed to secure immediate permanent employment for Nasatir.
So by the 1920s it would appear that Bolton supported the recruitment, training, and placement of Jews in the academy.
From that moment, Ehrman underwrote the publication costs of most of Bolton's books.
Despite his relationship with Ehrman and support for Jewish students, Bolton chaired a history department that had never hired a Jewish professor.
(28) Despite Schevill's unsupportive assessment, Bolton wrote to Kantorowicz inviting him to join the Berkeley history department as visiting professor of medieval history for the 1939-1940 academic year: "I am writing to welcome you and to make arrangements for the courses which you will give." He assigned Kantorowicz the standard course load of two undergraduate classes and one graduate seminar per semester and allowed him to suggest the particular topics for each course.
Whether Kantorowicz was hired because Sproul insisted over Bolton's objection or because Bolton privately recommended Kantorowicz remains an open question.
If Bolton objected to Kantorowicz joining the history faculty, anti-Semitism might not have been his motive.
There is one other motive that Bolton may have had.
Exposure to Kantorowicz seemed to eliminate whatever objections Bolton may have held against him.
The year after Bolton recommended Kantorowicz for a permanent faculty position, he wrote a letter of recommendation for Woodrow Borah, who wanted an assistant professorship at Tulane University.
(37) He was impressed with the magnificent architecture and the student body, who were "a healthy, happy group," he told Bolton. They were "so well trained in good diet that their instinctive tendency" was "to reach for milk," which he was surprised to find was served even at Princeton dances.
In 1946, he wrote Bolton a long letter summarizing his experiences.
