The exhibition was interesting. Among other things, we learnt that, so long as you do not wish to change the object under observation or adjust the focus, a holographic microscope works just as well as a physical microscope: if one looks through the eyepiece, the magnified object can be seen in sharp focus. This was one of various holographic plates that had been made as proof of concept, we were told: holographic technology has many applications, spread across diverse fields, including medicine, tourism, and conservation.
I was keen to investigate the future evolution of this technology, as I am always collecting ideas for future projects, so I conversed with the organiser at some length. Somehow we ended up on the topic of cloning, at which point the organiser stated that the idea had originated in Germany. This would not have surprised me, had the organiser not then gone on to suggest that this had been a Nazi invention. His account of the research having been motivated by a desire to replicate the Aryan race struck me straightaway as apocryphal, particularly as he stated that for the Nazis "people who were not blond and blue-eyed were essentially monkeys". This statement is obviously incorrect, because while the Nazis idealised the pure Nordic type, almost none of the top Nazis - least of all Himmler and Goebbels - fit that description; in fact, only a minority of Germans fit that description. Moreover, while the Nazis did set up stud farms for the SS, I had never heard of the Nazis having been involved in attempts to clone humans.
Upon returning home, it did not take long before I found the origins of the story: it seems to be a 1976 novel by Ira Levin, called The Boys from Brazil, which was made into a film in 1978. While I found multiple references to modern research on cloning being characterised by fearful interests and organisations as "Nazi-like", I found no non-fiction sources claiming that the Nazis were ever involved in human cloning.
The first mammal was only successfully cloned in 1996, and the mammal in question was a sheep called Dolly.
