Bob was a titan in the cataloguing field and many items are known today because of his dedication to the whole process.
In passing, all I can say as a fellow cataloguer, I admired him greatly.
Please note TS O'Connell's information is posted below -- he may be able to provide more details
I don't know if I am doing this properly but I wanted to tell as many Krause Publications friends as possible that our dear friend Bob Lemke passed away this morning at a hospital near his home in Central Pennsylvania. People in the sports collecting hobby/business know what a towering figure he was and his influence and impact over almost four decades was enormous. I can be reached directly at
