The text follows the history of the Butantan Institute's Arthropod Laboratory from its foundation to the mid-1967 retirement of Wolfgang Bücherl, one of Brazil's greatest arachnologists. Information is drawn from several sources: annual reports by Vital Brazil, director of the Institute, from the periods 1900-1919 and 1924-1927; works published as part of Memórias do Instituto Butantan; and my personal experience with the Institute's researchers, technical staff, and contributors, as Bücherl's assistant starting in 1961.
