A. Adolf Schmidl (1802-1863) was the first person to regard speleology as a single coherent subject. Besides making important new explorations, he studied karst hydrology and underground meteorology and was also closely concerned with the work of others on cave fauna and flora. His publications ensured that his achievements were known to his successors, but his influence was less widespread than that of Martel who nevertheless called him “the real originator of speleology”.
