Schlumberger brothers
Conrad Schlumberger (2 October 1878 – 9 May 1936) and Emile Henry Marcel Schlumberger (21 June 1884 – 9 May 1953) were two French brothers from the region of Alsace-Lorraine, France, then a part of the German Empire. Their inventions in the area of geophysics and well logging were the beginnings of Schlumberger Well Services and the entire well logging industry. They held both French and German citizenships.
