The internet is amazing. I’ve known for awhile that my Grandfather was interviewed in a LIFE magazine. It was the “one with Ms. Monroe on the cover”, which didn’t really help narrow it down. I did try to find it if I was at antique mall or somewhere else that sold old LIFE magazines. I never managed to find it alas.
Google has taken to scanning ALL the LIFE magazines though, and made my search much much easier. I found the article here.
