Albrecht Dold R.I.P.

The depth of content and clarity of presentation that we saw in Albrecht Dold's 1960 Columbia course had a lasting impact on several, including me. I well remember the generosity he showed me in Heidelberg 1965. Myles Tierney and I will not forget that it was in the house of Albrecht and Yvonne in 1969 that we agreed to collaborate on the elementary theory of toposes. There are so many things that I still hoped to ask him..... Bill [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
