Abstract

W. H. Schikhof (1937–2014) is considered one of the founders of p-Adic Analysis and devoted his mathematical life to expand the frontiers of this area of knowledge. At the same time, he was a loyal friend and colleague, a concerned teacher and an affectionate family man. Many of us are thankful for the privilege of having been his friends and sharing his ideas. In this article we will shortly state some biographical facts. Then we will point out and discuss different areas in which his research was crucial. At the end we present a complete list of his books and published articles.
