Kathy was the other half of Yoda’s body on EMPIRE STRIKES BACK.  Confused? Well, as Frank Oz’s right arm operated Yoda’s neck, jaw, lips, nose and eyebrows, and Frank’s left arm operated Yoda’s left arm, Kathy operated Yoda‘s right hand and any other parts of the body that needed animating. Because the production executives were sensitive to union issues, she was never credited as a Yoda puppeteer. Instead she was credited as a “performing assistant: Yoda.” Consequently her contribution to Yoda went largely unnoticed.

Kathy is an actress, voice actress, and puppeteer who began working with Jim Henson on the third season of The Muppet Show, primarily as Gaffer the Backstage Cat. She was closely associated with several Jim Henson projects.  She was a voice director for DOG CITY, was a muppet designer for THE MUPPET MOVIE. She was a key performer for FRAGGLE ROCK, where she created the character of Mokey. She performed the Gelfling Kira in the movie THE DARK CRYSTAL.

After Jim’s death she was one of the creators of ALLEGRA’s WINDOW where she operated Allegra and in 2000 she was also one of the creators of the TV series BETWEEN THE LIONS.

Kathy, with her husband, (another former Muppet designer), Michael K. Frith, joined forces with the British charity "No Strings" to create the film THE STORY OF THE LITTLE CARPET BOY for children in Afghanistan, warning of the dangers of land mines.
