Gustav Schulze (1881-1965) was a Mexican-German geologist who was the first scientist to study the geology and paleontology of Picos de Europa and Cantabrian Mountains.
His father was Adolf Julius Schulze, a Bavarian merchant emigrated to Mexico and his mother was María Ziehl, a Mexican woman from a German origin family.
In his first visit to Spain in 1906 he began studying the coast of Llanes; after that he went to Cangas de Onís where he organized an expedition to the Picos Western Massif.
He was the first geologist who explained the geological structure of Picos de Europa, but the beginning of World War I cut his career as a scientific and university teacher in Germany.
[1] He researched Cantabrian Range and Picos without preconceived ideas, which allowed him to reach correct scientific understanding of the origin and formation of these mountains.
At least, the late discovery of his forgotten field notebooks has allowed science to be aware of the enormous importance that his studies would have had at the time and may his name be remembered for this reason.
