All contributions in the current memorial volume are briefly commented upon, with the emphasis on how these issues touched upon, or were linked to, the long and productive professional careers of the late Felder brothers, in the fields of geology, palaeontology and human prehistory. Pertinent literature references are added, some of which are covered in the various papers, while others illustrate their wide range of interests and prolific publishing lives.
