The Burroughs B-5700 MCP (a virtual memory batch OS system with an OS
written in ESPOL, a system-programming language based on ALGOL... which
goes back at least into the early 1960s if not actually 1957) supported
co-routine threads in their XALGOL dialect... though it wasn't a widely
known (or likely widely used) feature. Burroughs was never very good at
tooting its own horn, and IBM is generally given credit for inventing VM
quite a while later. The same is true for later research into threading.

And, I think the following is quite interesting too
(on "FUD" history; IBM/Burroughs/...):
