I met Kathleen once, at a Society for the History of Astronomy event in Chethams Library, Manchester. She interested herself to me and apologised for not beign able to hear anything I said! She was delighted to hear that I had read and enjoyed a paper by her on the structure of magic squares in the bulletin of the IMA (Institute for Maths and Its Applications).
The previous night I had lectured to Liverpool AS and been completely upstaged by another nonagerian, Eric Strach. The world is a poorer place for the passing of these two characters.
