When I was a boy, in the 1960's, there was an elderly couple who were revered as anointed. Each year everyone would crane their necks to see them partake. It was VERY unusual to see an anointed person in kingdom halls even then. They were a nice old couple but not anything special among us. I have no idea what happened to them. Since anointed people were OLD in my experience, I had a suspicious view of anyone who claimed to be anointed if they were younger than the Culicks.
There was one lady in the 1970's who claimed the call. She was in her early 40's. She said she heard a voice calling her name. It was Jehovah!
Right then I figured she was a nutjob. In the 1990's she was involved in a major purge of "Rockers" in the Bay Area. It was a group of "anointed" individuals who would sit and read the Bible and then rock back and forth when they found a new truth. The society star chamber hunted them and DF'd them all. Good times.
