In Carl Hagenbeck’s autobiography “Beasts and Men” (English translation, 1909) he writes:-Found some notes on this one :
1895 Hagenbeck sold a Leopard and a Puma to a menagerie-owner in Great Britain and here the pair bred 3 times. Each birth contained 2 young but of the 6 born only one survaived. This male was later sold ( again by Hagenbeck ) to the Zoo of Berlin were it died 1911.
Skull and skill are still to be found in the Natural History Museum in Berlin.
Its still not complete clear which of the parents was male and which female.
In an note in some kind of magazine its said the Leopard was the male and the Puma the female, on the label in the museum its however Puma-male and Leopard-female.
"A cross between a panther and a puma was undertaken, at my suggestion, at a small English menagerie. A number of young ones were born, but they all died except one, and there was nothing very noteworthy about the survivor."
Unfortunately Hagenbeck doesn't record the name of the "small English menagerie".
In addition, both “Cats of the World” (Armand Dennis; 1964) and “Mammalian Hybrids” (Annie P. Gray; 1975) record that Carl Hagenbeck bred a leopard x puma hybrid in Hamburg around 1900 which was successfully reared by a fox terrier bitch.
There are photos of a leopard × puma hybrid in the Tring Zoology Museum here:
