Question: Who owned the team that won the 1998 Leinster Senior Football Championship? Passage:Karl O'Dwyer was a footballer from Waterville in South Co Kerry. He played with the Kerry team that were shocked by Clare in the final of the 1992 Munster Senior Football Championship. He later played with Kildare and had much success when his father Mick was manager. In 1998 he helped Kildare to their first Leinster Senior Football Championship title since 1956, he later helped his team to a first All Ireland final since 1928 but lost out to Galway on the day. In the semi final Kildare beat O' Dwyers native Kerry. At the end of the year he picked up an All Stars Award at Full Forward. In 2000 he once again helped Kildare to a Leinster title. O'Dwyer retired from inter-county in 2002 following Kildare's defeat to Kerry in the All-Ireland Qualifiers.

Question: What profession did Fritz Haber work in the year Barschall received his Ph.D? Passage:Barschall was born as Heinrich Hermann Barschall in Berlin, Germany; his father was a patent attorney who had received a Ph.D. in chemistry after studying with Nobel Laureates Emil Fischer and Fritz Haber. After beginning study in several universities in Germany, he emigrated to the United States in 1937 during the early Holocaust period; though raised as a Lutheran, he had some Jewish ancestry. He received his Ph.D. from Princeton University in 1940 under the direction of Rudolf Ladenburg; he also worked closely with John A. Wheeler. After a suggestion by Niels Bohr, he carried out in only a few days with fellow graduate student Morton H. Kanner the first demonstration of fission by fast neutrons and thorium and uranium. His thesis was on the interaction of fast neutrons with helium. In a paper with John A. Wheeler he reported the discovery of spin-orbit coupling in neutron scattering.

Question: How old was Eric Temple Bell when Ross was an assistant professor at St. Louis University? Passage:Ross married Bertha (Bee) Halley Horecker, a singer-musician and daughter of Ross's Chicago neighbors, in 1931, received a National Research Council Fellowship for 1932, and worked as a National Research Council postdoctoral fellow at California Institute of Technology with Eric Temple Bell until 1933. Ross moved back to Chicago and led the mathematics department at an experimental school started by Ph.D.s during the Great Depression, People's Junior College, where he also taught physics. Ross became an assistant professor at St. Louis University in 1935 and stayed for about 11 years. In an interview, he said he advocated for a student who became the first black woman in the South to receive a master's degree in mathematics. This exception led the university to admit black students despite the idea's widespread unpopularity. During World War II, Ross served as a research mathematician for the U.S. Navy. He befriended Hungarian mathematician Gábor Szegő while in St. Louis, who recommended Ross for a 1941 Brown University summer school that prepared young scientists to assist in the war, a program Ross attended. He occasionally worked on proximity fuzes for Stromberg-Carlson's laboratory from 1941 to 1945 before accepting a position as head of University of Notre Dame's mathematics department in 1946. He set out to change the school's research climate by inviting distinguished mathematicians including Paul Erdős, whom Ross made a full professor.
