Leslee Asch (also credited as Leslie Asch) was employed by Jim Henson as part of the NY Muppet Workshop in the late 1970s. She built characters for Emmet Otter's Jug-Band Christmas and moved on to character builds for The Muppet Show, Fraggle Rock, The Dark Crystal, Sesame Street, and other Muppet productions. Because of her very solid knowledge of world puppet history, she was recruited to be part of The Jim Henson Foundation, whose function it is "to promote and develop the art of puppetry in the United States." She remains with the foundation as a board member.
