No. Brothers. English. Alan Ebringer now retired, is an immunologist and rheumatologist, headed up Middlesex Hospital Rheumy dept. He invented the NSD diet. His bro lives in Oz. Forget the brother's christian name.
The second of the Amazing Ebringer Brothers is called "Roland" and he is a rheumatologist right here in Melbourne, where I live!

It's a bl@@dy long trek to the other side of 'town' to see the man, but well worth the trip! He is either a home-grown Aussie, or a Brit who has worked long and hard to perfect his colonial accent!
(Trivia: His son Tim is a lecturer at Melbourne Uni in IT security, and works with the profoundly gifted son of one of my best friends - onto his second degree at just age 18!)
