Born in Guben in 1856, Alexander Tschirch trained in pharmacy in Dresden and at the state apothecary in Bern before continuing his studies in Berlin and Freiburg. He went on to build a career that crossed both German and Swiss academic life, eventually becoming closely associated with the University of Bern.
Tschirch is best remembered for his work in pharmacognosy, the study of medicines derived from natural sources. He researched plant anatomy, resins, and anthraquinone glycosides, and he also contributed to standards for testing medicines, helping make pharmacy more rigorous and scientific.
He served for many years as a professor of pharmacy and pharmacognosy in Bern, where his teaching and research left a lasting mark. Tschirch died in 1939, but he remains an important figure in the history of pharmaceutical science and medicinal-plant research.
