This work is intended to honour Professor Dr. Heinz Charles Kohler due to his recent death. While reviewing his work, especially in the field of karst geomorphology one can confirm his pioneering character in the modern study of the Brazilian limestone tropical karst. Even though it is very difficult or almost impossible to summarize a whole life in just a few pages, it is the author's intention to recall some of Dr. Kohler's most important works related to karst.
