During the research for their publication of The Letters of Louis D. Brandeis and The Family Letters of Louis D. Brandeis, Melvin Urofsky and David Levy photocopied and transcribed a number of letters held by the descendants of Brandeis' daughter, Susan Gilbert. After the volumes were published, the copies were incorporated into the Brandeis collection. Most of the letters are from Brandeis and are addressed to his wife Alice, daughter Susan and son-in-law Jack Gilbert. There are also a handful of letters addressed to other people, primarily Brandeis' other daughter Elizabeth, his brother Alfred and associate Jacob deHaas. There are also a number of untranscribed letters written by Alice Brandeis. Only a fraction of the letters in these boxes were published by Urofsky and Levy. Due to the personal nature of these letters, researchers will need permission from the Brandeis family to be able to view this material.
