By the Grace of G-d 2nd of Iyar, 5721 Brooklyn, N.Y.
Prof. Dr. David Baumgardt
The Fleetwood
Long Beach, N.Y.
Greeting and blessing:
Thank you for your letter of the 24th of Nissan.1
Since you decided to quote the references to ’סנדל in your forthcoming volume, which were mentioned in the footnote to page 202 of Sefer HaMaamarim, I had another look at the copy of my previous letter to you. I discovered that some additional important references to this subject were inadvertently omitted in my letter. These concern the treatment of the subject in the works of Rabbi Schneur Zalman Torah Or and Liqqute Torah, namely:
Torah Or, Kehot Publication Society, Brooklyn, N.Y., 1955, pp. 12d; 42b; 72a; 73c.
Liqqute Torah, Wilno, 1928, Vol. II, Shir haShirim, p. 43c f., a.a.
No doubt you are aware of the book Malakhe 'Elyon by Reuben Margaliyot (Jerusalem, 1945) entirely devoted to the names of the angels mentioned in the Talmud and Midrashim and (in notes) also to later sources.
And אחרון אחרון חביב, I was pleased to hear that your health is steadily improving, and may G-d grant you soon to enjoy a complete recovery.
With blessing2
Notes and sources
Prof. David Baumgardt (5650–5723) was a professor and lecturer in the history of philosophy at the University of Berlin until 1935, when he was forced to leave Germany with the rise of the Nazi regime. In his later years, he devoted himself to writing several works on mysticism. It is worth noting that the Rebbe studied at the University of Berlin studied at the University of Berlin during the period in which Baumgardt taught there.
This letter is a follow-up to letter of 10 Nissan, 5721, in which the Rebbe provides Baumgardt with references to several sources discussing the angle Syndalphon, a subject he was studying.
1) Quoted in a footnote to the previous letter.
2) A follow-up letter to Baumgardt is dated 20 Sivan 5721.
