physicist, seismologist, and meteorologist. He was the first director of the Austrian seismological service and a reputed academician of international accomplishment. He was politically victimized twice, in 1919 for his ethnicity and in 1934 as a socialist. He emigrated to the United States in 1938, continuing his academic career in New York, California, and Cambridge. Conrad's scientific work is documented in more than 240 papers concerning meteorology, climatology and seismology. In 1944, he published "Methods in Climatology" (Harvard University Press). Later editions, starting in 1950, listed Leo W. Pollak, as second author. He was the first to deduce the

and obtained his doctorate in 1900. Conrad became a University assistant at the "K.K. Centralanstalt für Meteorologie und Erdmagnetismus" (the Central Institute for Meteorology and Geodynamics) in 1901, mostly working at the Sonnblick high-altitude observatory for the next three years. In 1904, when the Seismological Service of Austria was established, Conrad was appointed head of the new department and became responsible for the seismic monitoring on Austrian territory. Among his first programs was a microseismic survey in 1905.


Professor at Czernowitz and Vienna

In 1910 Conrad accepted a newly created chair for "cosmic physics" at the

After the dissolution of the Austro-Hungarian monarchy at the end of World War I the university was rumanized and Conrad was forced to leave Czernowitz at the end of July 1919, losing not only his professorship but also his private assets. He returned to his former position at the Central Meteorological Institute and later as a full professor at Vienna. During his analyses of two earthquakes that occurred in Austria in 1923 and 1927 he discovered what is today known as the

Emigration and further career

As a member of Austria's socialist party, Conrad faced political discrimination after the brief and decisive Austrian Civil War. On April 30, 1934 he was put on leave with waiting pay. He retired in 1936, and emigrated to the United States in 1938 where he once again brought his career to bloom, 1940-1942 at

The Conrad observatory

When Victor Conrad died at Cambridge in 1962, his widow Ida bequeathed the majority of the couple's assets to the Austrian Central Institute for Meteorology and Geodynamics, on the condition that the funds be used to establish a research institution bearing her late husband's name. This took place in the form of the Conrad Observatory for Seismology, situated about 50 km from Vienna near Gutenstein. Its module for seismology and
