Friedrich Ahlfeld

Friedrich (Federico) Ahlfeld is internationally known as the "Father of Bolivian Geology," having published a great many works on the geology and mineralogy of that country. The Bolivian mineral ahlfeldite was named in his honor in 1935. He was born in Marburg, Germany and studied at the Clausthal Mining School. His specialities were economic geology, ore deosits, ore genesis, and metallogenic belts. He worked for many years at the great Bolivian tin, tungsten, antimony and silver mines, including numerous famous mineral localities,and built several substantial mineral collections. One was purchased jointly by Harvard and the Smithsonian in 1932. He sold off many of his specimens in the 1970's through everal American dealers (including Jack Young and Charles Key), and his widow sold others (to Terry Szenics) following his death in 1982. Ahlfeld's son, Manfred, still retains a portion of the collection at his residence in Mexico.
