Louis Agassiz donates his collections to the new Museum of Comparative Zoology in Cambridge, Massachusetts

Swiss-born scientist Louis Agassiz had emigrated to the United States in 1846 and had long desired to set up an influential museum of comparative zoology.  The museum finally opened in Cambridge, Massachusetts with the remarkable gift of all of the professor's personal collection in zoology he had been gathering during the decade.  (By John Osborne)
