My grandmother worked in the oil industry around that time. I think she was at Gulf in the 60's / 70's before moving on to Shell and retiring in the later 80's.

My grandmother worked in the oil industry around that time. I think she was at Gulf in the 60's / 70's before moving on to Shell and retiring in the later 80's. When I was too young and unknowing she would lecture me about her work in Fortran and other languages in her systems analysis work. Unfortunately she lost her mind and passed away before I had the chance to question her in my own better state about her work.
