Bonnie Beecher (born 25 April 1941; age 83) is a former actress who played Sylvia in the Star Trek: The Original Series third season episode "Spectre of the Gun". She filmed her scenes on Tuesday 21 May 1968, Wednesday 22 May 1968 and Monday 27 May 1968 at Desilu Stage 10.
Prior to the start of her acting career, Beecher had briefly been the girlfriend of singer Bob Dylan while both attended the University of Minnesota in 1961. She recorded some early Dylan performances in her apartment, and it is alleged that Dylan's song "Girl From The North Country" was inspired by Beecher.
Beecher's subsequent acting career was relatively brief, and was confined to guest-starring roles on American TV series. She debuted as the mysterious folk singer Mary Rachel in the 1964 The Twilight Zone episode "Come Wander With Me", and also appeared in episodes of The Invaders, The Fugitive, and Gunsmoke, among other shows. Her Star Trek appearance and an appearance on The Outsider, aired a month later, were the last two roles of Beecher's career before her retirement from acting while still in her twenties.
In 1967 Beecher married counter-culture icon Wavy Gravy (né Hugh Romney, and best known as the MC at Woodstock and Woodstock II). The two are still married, and Beecher now goes by the name Jahanara Bo Romney. With her husband, she helps run a number of charitable organizations.
