Wilhelm Phillip Daniel Schulz (6 March 1805 â 1 August 1877), also known in Spain as Guillermo Schulz, was a German mine engineer and geologist who spent most of his professional life in Spain. He was born in Dörnberg and died in Aranjuez.
On April 18, 1823, he began studying mining engineering at the Georgia Augusta University of Göttingen. Upon completing his studies, he was hired by a mining company that operated the lead mines of the Sierra de Gádor in AlmerÃÂa. Shortly was hired by the Spanish Government to enhance the mining industry in the country. Around 1830 he returned to Germany. The Spanish government was very interested in hiring him, and in 1830 sent him to Silesia, where he was staying, his appointment as Commissioner of Mines. Before he returned to Spain, he was tasked with visiting several German and Hungarian mines and factories to further perfect his knowledge. In 1831 he returned to Spain, and the General Directorate of Mines commissioned him to study the geology of Galicia and to prepare the corresponding petrographic map. In 1833 he was appointed Mining Inspector for Asturias and Galicia, and in 1844 General Mining Inspector for Asturias. It was in Asturias where, for many years, he carried out outstanding geological and industrial work which he made public in several books. In 1854 he moved to Madrid, where he taught in the Mining Engineering School and was vice-president of the Geological Institute.
