The UK Synaesthesia Association (UKSA), under its original guise as the International Synaesthesia Association (ISA), was formed in 1989 making it the world’s first organised association for the synaesthesia “community”.   The brain-child of pioneering synaesthesia researchers Professor Simon Baron-Cohen and John Harrison at Cambridge University, it’s purpose was to bring together researchers and subjects in an environment where they could freely swap information.  It was very simply a list of synaesthete’s connected to a list of synaesthesia researchers.
