  • Note 2:

  • Henry Perigal was a stockbroker and amateur mathematician and astronomer, whose life spanned almost the entire nineteenth century and who is now known principally for an elegant cut-and-shift proof - what is now called a dissection proof - of Pythagoras' Theorem. He himself perhaps felt that this was his most important accomplishment - his diagram was carved, presumably at his own request, on his gravestone in Wennington Churchyard, Essex.

    He discovered a number of other interesting geometrical dissections, however, and both his life and his role in nineteenth century British scientific society are curious.
