Hello. I just read in your post in the PD Digest that (a) you're trying to reach Dr. Birkmayer and (b) that Dr. Birkmayer died about a year ago. Interesting predicament. I suspect that you're referring to 2 different people, however. There's Dr. Walther Birkmayer, who did pass away about a year or two ago; but there is also his son, Dr. Georg Birkmayer, who continues the work as head of the same Parkinson's Research Institute in Vienna, and also is an authority on PD & NADH. I believe that you can probably get a message through to Dr. Georg Birkmayer via contacting the Menuco Corporation (based in NYC), though of course I think it's always best to go straight to the source. -- SJS [log in to unmask] 11/13/98 ******************************
