Jean-Jacques Dozy (born June 18, 1908 in Rotterdam , † November 1, 2004 in The Hague ) was a Dutch geologist .

Life

Dozy was born the son of a police officer in Rotterdam. He studied in Leiden in the early 1930s and was one of the founders of the Leidse Geologische Vereniging (Leiden Geological Association), a society for geology students. During his studies, he climbed a mountain in Bergamo and thus conquered his first peak and then developed into an active mountaineer.

After his studies he went to the Dutch East Indies as a geologist and worked for the Royal Dutch Shell and its subsidiary, the Bataafse Petroleum Maatschappij (BPM), until his retirement in 1966. This led him to various countries, such as B. to Guatemala , Venezuela , Iran , including Indonesia and his Dutch homeland.

From 1980, he held a full professorship in geology at the Technical University of Delft .

Carstensz expedition

From October 1936 Dozy took part in the Carstensz expedition , together with the mountaineers Anton Colijn and the aviation officer Ing.Frits Wissel , to climb and explore the Puncak Jaya , also known as the Carstensz pyramid . Towards the end of 1936 he discovered the rock formation and mountain Ertsberg (in German: "Erzberg") at an altitude of 3600 meters in New Guinea as well as the Grasberg copper mine with corresponding copper ore deposits and small traces of gold . He explored the area in this area with his small expedition.

In 1939 he published some writings about it that were ignored because of the Second World War . 20 years later, his articles were rediscovered, leading to the rediscovery of the Ertsberg and the development of the Ertsberg and Grasberg mine complex, as well as copper mining there. The mineral Dozyiet found on the Ertsberg was named after Jean-Jacques Dozy .
