Nicolae Paulescu
Additional recommended knowledge
Early life and activitiesBorn in Bucharest, he was the first of four children of father Costache Paulescu and mother Maria Paulescu. He displayed remarkable abilities as early as his first school years. He learned French, Latin and Ancient Greek at an early age, so that a few years later he became fluent in all these languages and was able to read classical works of Latin and Greek literature in the original. He also had a particular gift for drawing and music and special inclinations towards natural sciences, such as physics and chemistry. He graduated from the Mihai Viteazu High School in Bucharest, in 1888. In the autumn of 1888, Paulescu left for Paris, where he enrolled in medical school. In 1897 he graduated with a Doctor of Medicine degree, and was immediately appointed as assistant surgeon at the Notre-Dame du Perpétuel-Secours Hospital. In 1900, Paulescu returned to Romania, where he remained until his death (1931) as Head of the Physiology Department of the University of Bucharest Medical School, as well as a Professor of Clinical Medicine at the St. Vincent de Paul Hospital in Bucharest. Paulescu's discovery of insulinIn 1916, he succeeded in developing an aqueous pancreatic extract which, when injected into a diabetic dog, proved to have a normalizing effect on blood sugar levels. After a gap during World War I, he resumed his research and succeeded in isolating the antidiabetic pancreatic hormone (pancreine). From April 24 to June 23, 1921, Paulescu published four papers at the Romanian Section of the Society of Biology in Paris:
An extensive paper on this subject - Research on the Role of the Pancreas in Food Assimilation - was submitted by Paulescu on June 22 to the Archives Internationales de Physiologie in Liège, Belgium, and was published in the August 1921 issue of this journal. Furthermore, Paulescu secured the patent rights for his method of manufacturing pancreine (his own term for insulin) on April 10, 1922 (patent no. 6254) from the Romanian Ministry of Industry and Trade. Nobel Prize controversyEight months after Paulescu's works were published, doctor Frederick Grant Banting and biochemist John James Richard Macleod from the University of Toronto, Canada, published their paper on the successful use of a pacreatic extract for normalizing blood sugar (glucose) levels (glycemia) in diabetic dogs. Their paper is a mere confirmatory paper, with direct references to Paulescu's article. However, they misquote that article, enunciating that:
which is exactly the opposite of what Paulescu found out. Later on, Banting said that
Surprisingly, Banting and Macleod received the 1923 Nobel Prize in Physiology or Medicine for the discovery of insulin, while Paulescu's pioneering work was being completely ignored by the scientific and medical community. International recognition for Paulescu's merits as the true discoverer of insulin came only 50 years later. Professor Ian Murray, an internationally regarded physiologist, was particularly active in working to correct the historical wrong against Paulescu. Murray was a professor of physiology at the Anderson College of Medicine in Glasgow, Scotland, the head of the department of Metabolic Diseases at a leading Glasgow hospital, vice-president of the British Association of Diabetes, and a founding member of the International Diabetes Federation. In an article for a 1971 issue of the Journal of the History of Medicine and Allied Sciences, Murray wrote:
Furthermore, Murray reported:
CriticismPaulescu has been criticized for expressing antisemitic and anti-Masonic views in articles such as The Judeo-Masonic plot against the Romanian nation. He was an associate of A. C. Cuza, and wrote extensively for the latter's newspaper Apărarea Naţională. Following protests from several Jewish organizations, the inauguration of Professor Paulescu's bust at the Hôtel-Dieu State Hospital in Paris, scheduled for August 27 2003, had to be cancelled.
However, such an opinion was not shared by Romanian Jew Nicolae Cajal, a member of the Romanian Academy of Sciences, who stated that there is a need to dissociate between individuals' private views and their scientific merit, mentioning that his own father, a student of Paulescu, admired Paulescu for his scientific skills, although he could not agree (as a Jew) with Paulescu's anti-Semitic views. HonorsPaulescu died in 1931 in Bucharest. He is buried in Bellu cemetery. In 1990, he was elected posthumously to the Romanian Academy. On June 27, 1993, in Cluj-Napoca, a postmark was dedicated in Paulescu’s honor to observe the World Day Against Diabetes. Paulescu was also honored on a postage stamp issued by Romania in 1994. The stamp is one in a set of seven stamps honoring famous Romanians. In 1993, a new Institute of Diabetes, Nutrition and Metabolic Diseases in Bucharest was named in his honor. |
