Hans Suess

• 1. Vienna Roots And Family Lineage

  ›

  Hans Eduard Suess entered the world on the 16th of December 1909 in Austria. He carried a significant family name as the grandson of geologist Eduard Suess. This lineage connected him to deep earth sciences before he chose his own path. Hans pursued higher education at the University of Vienna during the early twentieth century. He earned his Ph.D. in chemistry in 1935 under the supervision of Philipp Gross. The academic environment there shaped his approach to physical chemistry and nuclear physics.

• 2. Heavy Water And Wartime Advisory

  ›

  World War II brought Hans into the center of German scientific efforts regarding nuclear power. He served as an advisor for heavy water production at a plant located in Norway. Robert Jungk later recorded statements from Jomar Brun, a former technical manager of the Vemork plant. Brun stated that Hans told him production could not reach dimensions important for war production in much less than five years. These conversations occurred while German troops occupied Norway starting in 1940. The heavy water works sat at Rjukan where secret operations unfolded daily.

• 3. Atomic Shells And American Emigration

  ›

  After the conflict ended, Hans collaborated with future Nobel Prize winner Hans Jensen. Their partnership focused on developing the shell model of the atomic nucleus. This theoretical work laid groundwork for understanding how protons and neutrons arrange themselves inside atoms. In 1950, Suess emigrated to the United States seeking new research opportunities. He joined Harold Urey at the University of Chicago to study cosmochemistry. Together they investigated the abundance of certain elements found within meteorites. Urey had already won the Nobel Prize in Chemistry in 1934 for his own contributions.

• 4. Scripps Faculty And UCSD Founding

  ›

  The year 1955 marked a pivotal shift when Suess was recruited for the faculty of Scripps Institution of Oceanography. Three years later he became one of four founding faculty members at the University of California San Diego. He remained at this institution as professor until 1977 before becoming emeritus. His laboratory established there specialized in carbon-14 determinations for scientific analysis. Students like Ellen R.M. Druffel trained under his guidance during these decades. Druffel eventually became the Fred Kavli Professor of Earth System Science at University of California Irvine.

• 5. Carbon Distribution And The Suess Effect

  ›

  Hans dedicated his final research years to tracking carbon-14 and tritium distribution across oceans and atmosphere. He analyzed radiocarbon data from annual growth-rings of trees to calibrate dating scales. This work revealed how atmospheric radiocarbon dilutes due to carbon dioxide released by burning fossil fuels since the industrial revolution. Scientists now call this specific phenomenon the Suess effect. It remains a key concept in understanding anthropogenic greenhouse effects today. His findings connected ancient tree rings directly to modern climate change discussions.

• 6. Mineral Names And Final Years

  ›

  A mineral named suessite honors Hans Eduard Suess for his contributions to science. This Fe, Ni-silicate appears within Enstatit-Chondrites found in meteorites. On the 20th of September 1993, he died inside a La Jolla retirement home. His death marked the end of a long career spanning multiple continents. Postal services frequently confused him with children's writer Dr. Seuss while both lived in La Jolla. Their personal papers now share space together in Geisel Library at UCSD.
