The Spectator was smitten with Loretta Würtenberger and meeting with her and reading her book. You might want to look into it yourself.

In the coming weeks, we hope to be able to share with you some highlights from Würtenberger’s recent conference in Berlin.

Far from being an intimidating academic lawyer, Dr Würtenberger is tall and elegant with a disturbing resemblance to the unreasonably attractive Princess Caroline of Monaco. Speaking very confident English with an American accent, it’s impossible to decide whether she is an art-world poacher or a gamekeeper.

And she is impressively frank about not knowing quite what she is doing, although well aware too of the maxim ‘If I knew what I was doing it would not be research.’  […] Amazingly, there is at the moment no formal research on the subject. […]

She actually said ‘praxis’ to me, then twinkled her eyes, rattled her jewellery and smiled.
