Julie Cobb is an American actress who played Yeoman Leslie Thompson, the crew member reduced to a block and crushed by the Kelvans in By Any Other Name.
Julie Cobb (born 1947) made one of her first screen appearances in the second-season episode By Any Other Name. She plays Yeoman Leslie Thompson, a member of the landing party that answers the Kelvans' false distress call.
To demonstrate their power, the Kelvans reduce Thompson and Lieutenant Shea to small, porous blocks containing their essence. Rojan crushes one of them in his hand, and it proves to have been Thompson, while Shea is restored. Her death makes her one of the few women in a red uniform to be killed in The Original Series.
Cobb went on to a long career as a character actress in American television, including a regular role in the first season of Charles in Charge.
