Sabba S. Ștefănescu
Sabba S. Ștefănescu (born July 20, 1902 in Bucharest ; † April 15, 1994 ibid) was a Romanian geophysicist.
He was the youngest son of the professor of palaeontology at the University of Bucharest Sabba Ștefănescu (1857-1931) and Constanta Demetrescu-Negrea, went to school in Bucharest and in Paris ( Lycée Louis-le-Grand , Baccalaureate 1919), where his father served on a diplomatic mission from 1917. He graduated from the Ecole des Mines in Paris in 1923 and then went to Romania, where he worked as a geologist in mining ( Schiltal ) and from 1927 at the national geological institute. At that time he was engaged in geoelectric prospecting , which remained his main field of work. Through two publications he came into contact with the pioneers of geophysical prospecting Marcel Schlumberger and Conrad Schlumberger in Paris and worked with them in Paris from 1929 to 1933. He then went back to the Geological Institute in Romania, but was also a consulting engineer for the Schlumberger brothers' company.
In 1945 he received his doctorate in physics from the University of Bucharest. He taught geophysics at the Mining Institute and later at the Institute for Petroleum, Natural Gas and Geology (IPGG) in Bucharest. In 1967 he retired.
In 1946 he became a corresponding member of the Romanian Academy of Sciences (and a full member in 1963) and in 1950 he became head of the geophysics department in the Romanian Geological Committee. From 1966 to 1990 he was head of the geosciences department of the Romanian Academy of Sciences and he was president of the national committee for geodesy and geophysics. Until 1990 he published the magazine Revue roumaine de géologie, géophysique et géographie .
In 1990 he became an honorary member of the Society of Exploration Geophysicists .
Together with Liviu Constantinescu, he is considered the founder of geophysics in Romania. Stefanescu is known for theoretical and practical study of geoelectrics in prospecting, for example with creating some of the first realistic models in the 1930s and with regard to the magnetic fields created by electrical currents in the ground.
