American television director and production manager who is the credited director of four third-season episodes of the original Star Trek, including The Tholian Web and the final episode, Turnabout Intruder.
Herb Wallerstein worked in American television both as a production manager and as a director, and he became one of the more frequently used directors of the original Star Trek's final year.
He was brought in to take over The Tholian Web after Ralph Senensky was removed part-way through the shoot, and received sole screen credit for it. He then directed That Which Survives, with Lee Meriwether as the deadly projection Losira, and Whom Gods Destroy, set in the asylum on Elba II ruled by the deranged Garth of Izar.
Wallerstein also directed Turnabout Intruder, in which Janice Lester exchanges bodies with Kirk. It was the last episode of the series to be produced and broadcast.
