Wiesner: A Legacy of Chemistry and Pharmaceutical Innovation
The trajectory of scientific discovery is often shaped by resilience in the face of adversity. For the chemist known as Wiesner, his early academic pursuits were marked by the turbulence of wartime Europe, yet these challenges served as the catalyst for significant contributions to polarography and antimicrobial research.
Early Academic Pursuits and Wartime Discovery
Born into a notable and wealthy family in Prague, Czechoslovakia, Wiesner began his journey in the natural sciences in 1938 at Charles University. However, his formal education was abruptly halted in 1939 when the German occupation led to the closure of universities.
Undeterred by the lack of institutional access, he continued his research under the guidance of Rudolf Brdička at Bulovka Hospital. Utilizing a rudimentary laboratory established in his parents' basement, he developed a polarographic method—a technique using polarography (the study of current flowing through a solution at varying voltages)—to measure fast chemical reactions. Upon the reopening of Charles University in 1945, he was awarded a doctorate for this pioneering work.

Contributions to Antimicrobial Research
In 1943, during the height of World War II, Wiesner joined a research team at the Fragner pharmaceutical company near Prague. The group operated under strict secrecy and onerous wartime restrictions with the goal of developing a penicillin variant.
The team successfully separated and tested an antimicrobial drug. Wiesner played a critical role in the process by extracting and purifying the antibiotic from the urine of test subjects following their treatment, ensuring a steady supply of the substance for further study.
Global Research and Academic Career
Following the war, Wiesner expanded his expertise in organic chemistry. From 1946 to 1948, he conducted postgraduate research at ETH Zürich under the supervision of Vladimir Prelog, supported by a Rockefeller fellowship.
In 1948, he immigrated to Canada to join the faculty at the University of New Brunswick (UNB) in Fredericton. While he spent two years working with the pharmaceutical company Ayerst in Montreal, he spent the vast majority of his professional life at UNB. Beyond his laboratory work, he became a founding member of the World Cultural Council in 1981. He passed away in 1986 due to lymphoma.
