Hans Fischer was an eminent organic chemist from Germany. He was born on July 27, 1881, in Hochst on the River Main, now a city district of Frankfurt. He was famous for his groundbreaking work in organic chemistry, particularly in the study of porphyrins and hemoglobin. His father, Dr. Eugen Fischer, was the director of the firm of Kalle & Co, Wiesbaden, and his mother was Anna Herdegen.

Early Education and Academic Pursuits

Fischer went to primary school in Stuttgart. Later, he attended the “Humanistisches Gymnasium” in Wiesbaden in 1899. Interested in chemistry and medicine, he pursued his passion by enrolling at the University of Lausanne in Marburg. In 1904, he graduated from the University of Marburg and obtained his Ph.D. in chemistry, and in 1908, he earned his M.D. from the University of Munich.

Research Contributions in Organic Chemistry

Hans Fischer’s most notable research focused on porphyrins and hemoglobin. He successfully synthesized hematoporphyrin and determined its structure, laying the foundation for understanding the structure of hemoglobin. Fischer’s studies helped elucidate the functions of heme, a key component of molecules like hemoglobin, myoglobin, and certain enzymes.

Nobel Prize and Chlorophyll Research

Fischer was awarded the Nobel Prize in 1930 for his research on the structure and synthesis of hemin, a derivative of hemoglobin, and other compounds. He also worked on chlorophyll, a pigment found in plants. His research on porphyrins provided valuable insights into the structure and function of chlorophyll, enhancing our understanding of photosynthesis.

Academic Positions and Ethical Stance

Apart from his research, Fischer held various academic positions throughout his career. In 1911, he became a lecturer at the University of Innsbruck in Austria and later served as a professor of organic chemistry there. In 1921, he returned to Germany and became a professor at the Technical University of Munich. During the Nazi regime, Fischer faced pressure to fire his Jewish colleagues, but he strongly opposed these actions and disagreed with the unfair treatment.

Legacy and Death

Hans Fischer passed away on March 31, 1945, during the final months of World War II, at the age of 63. His funeral was held in Munich, Gau Munich-Upper Bavaria, Nazi Germany. Fischer’s work on porphyrins and hemoglobin significantly advanced our understanding of chemistry and biology.
