In 1925, James B. Macelwane, SJ, a seismologist at St. Louis University, wrote to Hubert Brockman, SJ, the president of Xavier University, about establishing a seismograph station on the Xavier campus. Father Brockman responded affirmatively. As a result, Xavier installed a seismographic vault in the basement of Schmidt Hall as the building was being constructed. In 1926, Xavier placed an order for 2 short-period and 2 long-period Wood-Anderson horizontal seismometers and a Wood-Anderson vertical apparatus with 5 recording drums. Daniel J. O’Conor, president of the Formica Co., contributed significantly to these purchases. In the summer of 1926, Vincent V. Herr, SJ, was appointed the director of Xavier’s Seismological Observatory with William J. Thiroff, SJ, as his assistant. In the fall of 1927, the newly installed equipment began to record data. Joseph Wilczewski, SJ, became the director of the Observatory with Clifford J. LeMay, SJ, as his assistant in June 1929. In August 1931, Father Wilczewski left Xavier and the Observatory was inactive until February 1932. As a result, the Observatory did not record the significant earthquake that occurred in Anna, County Shelby, Ohio on September 20, 1931. In 1932, Victor Stechschulte, SJ, (1893-1955) became director of the Observatory, which was immediately reactivated. Born in Leipsic, Ohio in 1893, he attended St. Louis University for his undergrad and then received his master's and doctorate from the University of California. On March 29, 1937, another earthquake occurred with an epicenter in Anna, Ohio and was recorded by the Xavier Seismological Observatory. Stechschulte also served as a professor of physics and director of the department of mathematics and physics. He remained director of the observatory until his death on March 3, 1955. Edward A. Bradley, SJ, came to Xavier to teach in the fall of 1957. Born in Cincinnati in 1923, he had attended St. Xavier High School before entering the Milford, Ohio Novitiate in 1941. He was ordained to the priesthood in 1954 at West Baden College, West Baden Springs, Indiana. He studied seismology at St. Louis University and John Carroll University. He became director of the Observatory in 1957, the position having been vacant for some months. Granted a leave of absence from Xavier, Bradley participated as a seismologist on a United States Navy expedition to Antarctic as part of Operation Deep Freeze II during the International Geophysical Year. He left Xavier in November 1957 and lived in Antarctica, based at Ellsworth Station which was located on the Filchner Ice Shelf of the Weddell Sea south of Cape Horn, from January 1958 to January 1959. Its purpose was to measure the thickness of the icecap that blankets that continent. While in Antarctica, he and his group made two long traverses over the ice, including a three-month, thousand-mile trek to Byrd Station using Snow-Cat tractors. Upon his return to Xavier, he gave lectures about his experience and returned to teaching physics. Sometime during his directorship of the Seismology Observatory, Father Bradley established a seismological station at the “Jesuit Farm” in Clermont County, Ohio. In 1975, Bradley was seriously injured in an automobile accident. After that he retired from the faculty and relinquished his position as director of the Seismological Observatory, which then ceased operations by the late 1970s. Bradley died in 1996. This historical sketch originates from the work of Thomas Kennealy, SJ.
