Samuel Irving Rosenman (February 13, 1896 – June 24, 1973) was an American lawyer, judge, Democratic Party activist, and presidential speechwriter.

Rosenman was responsible for the term "New Deal", a phrase in the conclusion of FDR's acceptance speech at the 1932 Democratic National Convention.

He was a member of its Survey Committee which worked to reduce antisemitism in the United States by promoting national unity.

The Committee considered some of the actions of Jewish activists as unproductive in promoting, rather than dispelling, notions of difference rather than of unity.

The Survey Committee emphasized the importance of unity in standing up to the Nazi menace, and was influential, in part through Rosenman, in having F.D.R.

[9] On October 6, 1943, three days before Yom Kippur, Hillel Kook (aka Peter Bergson) organized a march to Washington DC (the famous Rabbis March) by a delegation of some 400 rabbis, most if not all Orthodox and some recent immigrants, to make a public appeal to the United States government to do more to try to rescue the abandoned Jews of Europe.

It was later learned that Roosevelt had several free hours that afternoon, but was advised by both Stephen Wise (head of the World Jewish Congress) and Rosenman (who, in addition to being the President's advisor and speech writer, also headed the American Jewish Committee) that the protesting rabbis "were not representative" of American Jewry and not the kind of Jews he should meet.

"[10] Historian Rafael Medoff, founder of The David Wyman Institute (named after Holocaust historian David Wyman) characterizes Rosenman this way: "One of FDR’s top advisers and speechwriters was Samuel Rosenman, a leading member of the American Jewish Committee.

Rosenman was sensitive to the destructive charges that Roosevelt was led by a "Jewish cabal" and, as with many leading Jews, fearful that antisemitism in the United States could increase further.
