I studied Physics at Cambridge in the 90's (not Newnham). I remember Dr Padman teaching me in a practical my first term there. I remember us going back and telling our friends that evening about the big rugby player in a dress who'd been in the lab with us. It probably made the top 10 of bonkers things that had happened to me that week, then got quickly forgotten.
I wasn't aware of Germaine Greers view at the time, but I do remember being confused why he was at Newnham which I think was women only for fellows and students, which differentiated it from New Hall which had male fellows.
I also didn't 'get' women's only colleges at the time, was probably quite dismissive of them. I'd have hated to be at one myself.
Its an encounter I've thought about more recently with all this gender madness. Dr Padman is one of only 2 'trans' people I've come across in my life, both fleetingly. I suppose I just saw him as another male eccentric in a department chock full of them - which was something about the place I appreciated, but I wonder if 18 year old me had found him in with me in the women's toilets I'd have felt the same.
