in the 70's many of the people I knew in engineering were using forth as an 
embedded language. Of course the embedding was the final application as the 
controlling computers were really puny eg pdp8/9/11.

At that time the concept of free software hadn't even arisen. I believe forth 
was proprietary, but it was widely available to academics and many machine tools 
and similar control applications used it.
