Another researcher and I went to a museum in St. Petersburg, FL to see the Kennedy exhibit circa 2004. It was a holiday. They were taking down Robert White's Kennedy collection. The next day Robert White, the collector, died of a heart attack. I think he was 51. I met him at the Hudson library in Florida. He didn't seem sick to me. Here is a video about him. It lasts about 10:36 minutes. He collected stuff about many celebrities. I hope this link works.
