"I operate by a code that makes me responsible for what I do, makes me definitely, directly, genuinely responsible. I am precisely the kind of person I made myself out to be."
- Harlan Ellison

Pressure Curtain  
  A force field that creates a barrier that people can pass through but air cannot - an airlock in a spacecraft.  

This seems like an early use of this idea; it predates the use of a similar idea in Star Wars.

The civilians were chattering among themselves - "But there's no air in here!" Staley yelled.

"Not here, sir," Hasner said. He pointed. "Some kind of box thing there, makes like a curtain, Mr. Staley. Air can't get through it but we can."

The Marine Gunner stepped gingerly through the invisible barrier. He had to push. "Like - maybe kind of like the Field, Mr. Staley. Only not so thick."

From The Mote in God's Eye, by Larry Niven (w/J. Pournelle).
Published by Simon & Schuster in 1974

"They can build those magic pressure curtains," Staley reminded him.
