Abstract
Staff outings of Emil Kraepelin's Royal Department of Psychiatry were known as "catatonic walks". A remarkable number of important German and international visitors participated in 1906, Nicolas Achucarro, Henry Cotton, Eduard Flatau, Smith Ely Jelliffe, Gaetano Perusini, Edward Scripture, Maurycy Urstein and others. Many of Kraepelin's collaborators were inspired by his ideas and driven by scientific enthusiasm which contributed to significant scientific advances, but also took them to very different ends from dental and bowel surgery to psychoanalysis and eventually evidence-based medicine; from racial hygiene and nationalism to the presidency of communist Romania.
