Zootierliste mention 10 European collections which kept this species in the past ( Zoo Berlin, Frankfurt, Hagenbeck Hamburg, Munich, Aalburg, Basel Bristol Chester, Edinburgh and Antwerp.
The information on Zootierliste is however little and not always accuarate for example it mentions that Antwerp had its first Emperor penguin in 1965 but already in 1959 a specimen was brought alive ( however only for a short time ) into the collection. It was named "Hans".
Would be intresting to learn also more about other Emperor penguins in the other collections and esp. about the breeding-attemps at Aalborg.
