For the history, in 2009 I had exchanges of mails with Rafael Borowiecki (who also used the nickname of Hasse Riemann). I did not know him but he wrote that he was publishing a timeline and sent me a lot of questions about the works of Charles Ehresmann and myself on categories. I took a lot of time to respond to him in details, with corrections to some of his assertions and proposal of new entries. Since then I had no news from him, and most of the information I sent him does not appear in the present timeline. Andree [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
