First Jewish Woman in the United States Senate

Dianne Feinstein became the 'First Jewish Woman in the United States Senate' on '10 November 1992'. This achievement occurred in Washington, D.C., when she took the oath of office after winning California's 1992 special election. The date marks the beginning of her service in the U.S. Senate, where she represented California from 1992 until her death in 2023. This record is defined as being held by the earliest Jewish woman to take the oath and serve as a member of the United States Senate.

The claim is substantiated by contemporaneous reporting from the Jewish Telegraphic Agency, which identified Feinstein as the first Jewish woman senator at the moment she was sworn in. This reporting also distinguished her achievement from that of Barbara Boxer, who was also Jewish and elected that same week, clarifying that Boxer would enter the Senate at a later date. A chronological review of Senate records combined with this contemporary historical reporting confirms Feinstein's status as the first.
