Who was the first contestant voted out of the first season of 'Survivor'?

Sonja Christopher was the first contestant voted out of the first season of Survivor.

The vote occurred in the premiere episode of Survivor: Borneo, originally titled “The Marooning.” After the contestants were divided into the Tagi and Pagong tribes, Tagi lost the first immunity challenge and had to attend Tribal Council. The tribe voted out Sonja on Day 3, making her the first person eliminated by a vote in Survivor history.

Sonja received four votes, while Rudy Boesch received three and Stacey Stillman received one. The decision was influenced partly by Sonja’s performance in the opening challenge, although the vote also reflected the early uncertainty of a group that had only just begun living together. Her elimination set the basic pattern for the series: losing tribes would attend Tribal Council and decide which member would leave.

Sonja’s boot is sometimes confused with later famous early eliminations, such as B.B. Andersen or Gretchen Cordy. Rudy, one of the alternatives listed in the question, survived the first vote and became one of the season’s best-known personalities. Survivor: Borneo ultimately ended with Richard Hatch defeating Kelly Wiglesworth in a 4–3 jury vote.
