Eva Smolková-Keulemansová (1927–2024) was a titan of analytical chemistry, a pioneer of chromatographic methods, and a symbol of resilience. As the first woman to be appointed a full professor of chemistry at Charles University in Prague, she played a foundational role in transitioning chromatography from a niche laboratory technique into one of the most powerful tools in modern science. Her life was defined by an extraordinary trajectory—from surviving the horrors of the Holocaust to becoming the "First Lady of Chromatography."
1. Biography: A Life of Resilience and Scholarship
Eva Smolková (née Weilová) was born on April 27, 1927, in Prague, Czechoslovakia. Her education was brutally interrupted in 1942 when, due to her Jewish heritage, she and her family were deported by the Nazis. She survived three concentration camps: Terezín, Auschwitz-Birkenau, and Bergen-Belsen. Upon her liberation in 1945, she returned to Prague—reportedly walking a significant portion of the way—to find that much of her family had perished.
Despite the trauma and the multi-year gap in her schooling, she completed her secondary education in record time and enrolled in the Faculty of Science at Charles University. She graduated in 1949 and began her academic career at the Department of Analytical Chemistry.
Her career spanned the difficult years of the Cold War. Despite the restrictions of the Iron Curtain, she maintained a rigorous scientific standard, eventually earning her DrSc (Doctor of Sciences) and, following the Velvet Revolution in 1989, finally receiving her full professorship in 1992—a title long delayed by the political climate of the previous regime.
2. Major Contributions: Shaping Modern Chromatography
Smolková-Keulemansová’s primary scientific legacy lies in the development and refinement of Gas Chromatography (GC) and the study of Inclusion Compounds.
- Pioneering Gas Chromatography: In the 1950s, when GC was in its infancy, she was among the first in Central Europe to recognize its potential for separating complex mixtures. She focused on the fundamental mechanisms of the process, particularly the interaction between the mobile gas phase and the stationary liquid or solid phase.
- Cyclodextrins and Chiral Separation: Her most significant intellectual breakthrough was the use of cyclodextrins in chromatography. Cyclodextrins are ring-shaped sugar molecules with a hollow center. Smolková-Keulemansová realized these "molecular buckets" could be used to separate isomers—molecules with the same formula but different shapes. This was revolutionary for chiral separation, which is essential in the pharmaceutical industry to ensure that the correct "mirror image" of a drug molecule is produced (preventing tragedies like the Thalidomide crisis).
- Adsorption Systems: She conducted extensive research into gas-solid chromatography, exploring how different surfaces (adsorbents) could be modified to achieve higher precision in chemical analysis.
3. Notable Publications
Throughout her career, she authored or co-authored over 140 scientific papers and several influential textbooks. Some of her most impactful works include:
- Chromatografické metody (Chromatographic Methods, 1959): One of the first comprehensive textbooks on the subject in the Czech language, which educated generations of Eastern European chemists.
- Cyclodextrins in Chromatography (1982): Published in Reviews in Analytical Chemistry, this work solidified her status as a global leader in the use of inclusion compounds for chemical separation.
- Gas-Solid Chromatography (1976): A seminal review article that examined the theoretical limits of using solid adsorbents in gas analysis.
4. Awards & Recognition
Her contributions were recognized globally, bridging the gap between the Eastern and Western scientific blocs:
- The Tswett Medal (1978): Named after Mikhail Tswett, the inventor of chromatography, this is one of the highest honors in the field.
- The Nernst-Tswett Award: Awarded for her outstanding contribution to the development of separation sciences.
- The Hanuš Medal (1994): The highest award of the Czech Chemical Society.
- Honorary Membership: She was an honorary member of the Czech Chemical Society and several international chromatographic associations.
- Charles University Gold Medal: Awarded for her lifelong dedication to the institution and her role in elevating its international scientific profile.
5. Impact & Legacy
Smolková-Keulemansová’s legacy is twofold: scientific and institutional.
Scientifically
Her work with cyclodextrins paved the way for modern "supramolecular chromatography." Today, the pharmaceutical and environmental industries rely on the principles she helped establish to detect trace pollutants and purify life-saving medications.
Institutionally
She was a trailblazer for women in STEM. By becoming the first female chemistry professor at Charles University, she dismantled long-standing gender barriers in the Czech academic hierarchy. She was known as a demanding but deeply fair mentor, supervising dozens of PhD students who went on to lead laboratories across Europe and North America.
6. Collaborations
Smolková-Keulemansová was a master of scientific diplomacy. Her most notable collaboration was with A.I.M. (Bram) Keulemans, a world-renowned Dutch chemist and a pioneer of gas chromatography. Their professional partnership eventually became a personal one; they married in the 1980s. This union facilitated a rare level of scientific exchange between Czechoslovakia and the Netherlands during the Cold War.
She also worked closely with Jaroslav Janák, the inventor of the first commercial gas chromatograph in Czechoslovakia, ensuring that theoretical breakthroughs were quickly translated into practical laboratory instruments.
7. Lesser-Known Facts
- The "First Lady" Moniker: She was affectionately known among her peers as the "First Lady of Chromatography," a title she earned not just for her seniority, but for the elegance and precision of her experimental designs.
- Multilingual Lecturer: She was known for her incredible linguistic ability, lecturing fluently in Czech, English, German, and Russian, which allowed her to act as a bridge between scientific communities during the era of the Iron Curtain.
- Active into her 90s: Even after her formal retirement, she remained a fixture at the Faculty of Science in Prague. She continued to attend seminars and mentor young researchers well into her 90s, maintaining a sharp intellectual curiosity until her passing in early 2024 at the age of 96.
- A Witness to History: She often spoke about the importance of scientific truth as a defense against political ideology, a perspective forged by her survival of totalitarian regimes.
Eva Smolková-Keulemansová’s life serves as a testament to the power of the human spirit to overcome the darkest of circumstances through the pursuit of knowledge. Her work remains embedded in every chromatographic separation performed in laboratories around the world today.
