I worked during my missionary-service for a year in Brooklyn and Patterson, and lived in the same building as Lösch, The Bossert, the beautiful renovated hotel. I have met him several times in the library and had some conversations with him (half german half english), and he was very kind and interested in the missionary work. As I was the homeoverseer of the missionary-home in my assignment I invited hime to come over for a week or so on the island we served.
Then I mentioned the name of a german couple that lived with us and he was in the same Gilead class as that german brother. He really went there a couple of months after I had to leave for another assignment. We also met some times in the local liquor store in Montaguestraat where he used to buy botles of wine without shame or hipocresy, other bethelites would go to other stores in Brooklyn...or maybe because it was cheaper there :).
So I can't have a bad impression of him, the same as Jack Barr, he was in my congregation and offered inmediatly his own room in Patterson when I told him we had to go there, "nicer than the guest-rooms" , he said.
Ray Franz, I never met him but have first-hand stories from older missionaries who worked with him.
One told me at the time he was a district-overseer in Puerto Rico and that missionary took him to bible-studies, he just let the missionary go into the house and told him it was to hot to get out, "you do your study and I will read the newspaper",... in the car with the A/C on. So what kind of person does that? There are many more things about him that's why I hate the almost adoring style the way some ex jw's talk about him or taking nicknames as Ray Franz or Frantz, no offence but are you not getting from one cult to another?
