Book excerpt: Few medical or scientific addresses have so unmistakeably made history as the presentation delivered by Alois Alzheimer on November 4, 1906 in Tübingen. The celebratory event "Alzheimer 100 Years and Beyond" was organized through the Alzheimer community in Germany and worldwide, in collaboration with the Fondation Ipsen. This volume, a collection of articles by the invited speakers and of a few other prominent researchers, is published as a record of those events.
