Just a few observations on those mentioned so far that I recognized, not all I've known. All of those I mention were observed as an adult since my youthful impression might be different. It won't be all negative. Without an assembly program in front of me, the spelling may vary.
Don Graeber: My age. We pioneered in neighboring congregations in Arkansas in the early 70's. Don and Shirley were humble, conscientious, straight-laced. Don worked hard at public speaking, but was not naturally gifted. They went to Bethel as a couple. I ran into Don a couple decades later. He gave a talk at an assembly as a District Overseer and he sounded like one. Originally from Oregon.
Don Farmer: Very meticulous with his personal belongings, car, trailer, etc. Sometimes viewed as arrogant, but I didn't pick up on that. A so-so public speaker. When the water pump malfunctioned at our rural Kingdom Hall during his visit, he took it apart, formed a gasket out of gasket paper and made a repair. Don was not hyper, more laid back. His wife was a photographer who did not hide her fondness for The Beatles.
Gene Shalkoski: Definitely old school, somewhat self-righteous. He liked to keep publishers, especially elders out in field service beyond their comfort zone. We once worked five hours in door-to-door after a Sunday meeting. I'm not certain what he was trying to prove, but no one wanted to be the first to suggest we call it a day.
Kenneth Dull: From the Seattle area. We met him, though in south Texas, his second circuit. He did not have a trailer then, staying with publishers in their homes. He was very conservative, not impressed with gladhanders or brothers with money.
Koinjavich: District Overseer. Total asshole. He had a fetish about the microphone cord. Met him when I was an established elder. Not impressed.
Fred Lanier: Fatherly. Wife: Gloria, I think. Possibly from Georgia.
Eugene Brandt: sort of legendary District Overseer. He married a sister from San Antonio, but originally from Philadelphia. Very good speaker, but not enjoyable on a personal level. He was reduced to Circuit Overseer briefly as sort of a punishment for some indiscretion. At least that's what he told a couple of us.
I'll stop there. . . . . . .tms
