Ignatz VenetzBorn 21 Mar 1788; died 20 Apr 1859 at age 71.Swiss geologist who was one of the first to propose that vast glaciers once covered a substantial portion of the earth's surface. He came to this conclusion by observing that typical striations left in rock by glaciers extended for many miles beyond the limits of existing glaciers. He published these thoughts in 1821, but they were generally ignored. Jean de Chapentier supported Venetz in these ideas, but was also ignored. However, they influenced Louis Agassiz who developed them.[Name also spelled Ignaz or Ignace.] |
