Jonathan Sarna, professor of American Jewish history at Brandeis University, author of numerous books including, very recently, Lincoln and the Jews: A history, which he co-edited with Benjamin Shapell. The book, which was published by St Martin's Press, recounts the relationship of the 16th president of the United States with a then still small and relatively uninfluential ethnic group, based on hundreds of archival items, some of them newly unveiled.
