Richard Lewisohn

Richard Lewisohn (1875–1961) was a German-American surgeon and medical researcher known for his pioneering work in the field of blood transfusion. His research significantly contributed to the development of safe and effective blood transfusion techniques, which have saved countless lives over the years.

Early Life and Education

Richard Lewisohn was born in Hamburg, Germany, in 1875. He pursued his medical education at the University of Freiburg and the University of Munich, where he developed a keen interest in surgery and medical research.

Career

After completing his education, Lewisohn began his career in Germany but moved to the United States in the early 20th century due to the rising political tensions in Europe. He joined the Mount Sinai Hospital in New York City as a surgeon, where he would make his most significant contributions to medicine.

Contributions to Blood Transfusion

Lewisohn's work in the early 1900s focused on overcoming the challenges associated with blood transfusion, which at the time was a risky procedure due to the rapid coagulation of blood outside the body. His research led to the discovery of the anticoagulant properties of sodium citrate, which when added to blood in controlled amounts, prevented clotting without harming the patient. This breakthrough, published in 1915, made blood transfusions safer and more practical, paving the way for the establishment of blood banks and the widespread use of transfusion in medicine.

Legacy

Richard Lewisohn's contributions to the field of blood transfusion have had a lasting impact on medicine. His work not only made transfusions safe and commonplace but also opened the door for advancements in surgery, trauma care, and the treatment of blood disorders. Lewisohn's research is considered a cornerstone in the history of transfusion medicine.

Death and Honors

Lewisohn passed away in 1961, leaving behind a legacy of innovation in medical science. Throughout his career, he received numerous accolades for his contributions to medicine, including recognition from medical societies and institutions around the world.
