Q: I am looking for someone who was employed by this company in 1950 to 1960, somewhere during that time frame.
A: It seems the only reference to this company is a geneology page with someone who worked there. http://www.familyorigins.com/users/h/o/o/Fred-C-Hooper-Ca/FAMO2-0001/d12.htm Other than that, I'd honestly try the San Diego library. Find a good reference librarian to help you. I'm sure they have old newspapers and phone directories, maybe company reports too in their files. If a specific person was ever mentioned, maybe you could track them down and see if they remember the person you're looking for!
