Signature

Charles Louis Alphonse Laveran (18 June 1845 – 18 May 1922) was a French physician who won the

infectious diseases such as malaria and trypanosomiasis. Following his father, Louis Théodore Laveran, he took up military medicine as his profession. He obtained his medical degree from University of Strasbourg
in 1867.

At the outbreak of the Franco-Prussian War in 1870, he joined the French Army. At the age of 29 he became Chair of Military Diseases and Epidemics at the École de Val-de-Grâce. At the end of his tenure in 1878 he worked in Algeria, where he made his major achievements. He discovered that the protozoan parasite Plasmodium was responsible for malaria, and that Trypanosoma caused trypanosomiasis or African sleeping sickness.[1] In 1894 he returned to France to serve in various military health services. In 1896 he joined Pasteur Institute as Chief of the Honorary Service, from where he received the Nobel Prize. He donated half of his Nobel prize money to establish the Laboratory of Tropical Medicine at the Pasteur Institute. In 1908, he founded the Société de Pathologie Exotique.[2]

Laveran was elected to

National Order of the Legion of Honour
in 1912.

Early life and education

Alphonse Laveran was born at Boulevard Saint-Michel in Paris, to parents Louis Théodore Laveran and Marie-Louise Anselme Guénard de la Tour Laveran.[3] He was an only son and had an older sister.[3] His family was in a military environment. His father was an army doctor and a professor of military medicine and epidemiology at the medical school, École de Val-de-Grâce in Paris. His mother was the daughter of an army commander.[4]

At a young age, his family moved to Metz in northeast France where his father became professor at the military hospital. At age five, the family moved to Blida in Algeria, North Africa.[1] 1856, he returned to Paris for education, and completed his higher education from Collège Sainte-Barbe and obtained the bachelor's degree inscience (baccalaureate) from the Lycée Louis-le-Grand.[4] Following his father he chose military medicine and entered the public health schools, simultaneously at École Impériale du Service de Santé Militaire (Saint Martin Military Hospital) in Paris and the Faculté de Médecine (Department of Medicine) of the University of Strasbourg in 1863.[3] In 1866, he became a resident medical student in the Strasbourg civil hospitals.[4] In 1867, he submitted a thesis titled Recherches expérimentals sur la régénération des nerfs (Research Experiments on the Regeneration of Nerves) by which he earned his medical degree from the University of Strasbourg.[5]

Career

Laveran was appointed Aide-major at the Saint Martin Military Hospital soon after his graduation. During the Franco-Prussian War, he served in the French Army as Medical Assistant-Major. After serving at the battles of Gravelotte and Saint-Privat, he was posted to Metz, where the French were eventually defeated and the place occupied by Germans.[4] He was briefly taken as prisoner-of-war, but as a physician, he was sent to work at Lille hospital where he remained till the end of the war in 1871.[1]

As a civil war immediately followed (the Paris Commune from 18 March to 28 May 1871), he was stationed at the Saint Martin Military Hospital. In 1874, he qualified a competitive examination by which he was appointed to the Chair of Military Diseases and Epidemics at the École de Val-de-Grâce, a position his father had occupied. His tenure ended in 1878 and he was sent to Algeria, where he remained until 1883.[4] Working at military hospitals in Bône (now Annaba) and Constantine, he began to have experience in the study of blood infection as malaria was prevalent.[6] However, he was transferred to Biskra where there were no malarial cases and he investigated a disease called Biskra button. He returned to Constantine in 1880.[4]

From 1884 to 1889, Laveran was Professor of Military Hygiene at the École de Val-de-Grâce. In 1894 he was appointed Chief Medical Officer of the military hospital at Lille and then Director of Health Services of the 11th Army Corps at Nantes. By then he was promoted to the rank of Principal Medical Officer of the First Class. In 1896, he entered the Pasteur Institute as Chief of the Honorary Service to pursue full-time research on tropical diseases.[7]

Malaria and discovery of malarial parasite

Laveran had first encounter with malarial parasites while working at Constantine. Malaria was till then considered as a

endothelial cells from the spleen and white blood cells.[14] Malarial infection therefore erroneously known as pigmented white blood cells (melaniferous leucocytes).[15] Laveran was the first to think of such infected blood cells were by parasites, but his interest in the issue was ended by his transfer to non-malarial station.[4]

Soon after he returned to the military hospital in Constantine, Algeria, in 1880, Laveran discovered the cause of malaria as a protozoan, after observing the parasites in a blood smear taken from a person who had just died of malaria.[16] On 20 October, he first noticed the parasite in various forms and described it with, as later remarked, "accurate"[17] and "excellent freehand drawings."[6] His initial hunch that pigmented cells in malaria were due to parasitic infection became obvious as he observed not only pigmented cells, but also several cells with filaments that were moving about. He continued to investigate other cases of malaria and reported his discoveries on 24 December to the Société médicale des hôpitaux de Paris. He described three unique biological characters of malarial parasite: crescent or oval bodies that were transparent and had rounded pigment granules at the centre, spherical bodies that possessed three to four filaments capable of worm-like movements, and smaller spherical bodies that had small granules and lacked filaments.[18] The crescent or oval cells are now known as the gametocytes, filamented bodies as exflagellation (male gamete), and small spherical bodies as trophozoites.[19]

Laveran's report was published in 1881 in the Bulletins et Mémoires de la Société médicale des hôpitaux de Paris, and in English in

germ theory of diseases.[24]

However, Laveran's announcement was received with skepticism mainly because by that time leading physicians such as Theodor Albrecht Edwin Klebs and Corrado Tommasi-Crudeli claimed that they had discovered a bacterium (which they called Bacillus malariae) as the pathogen of malaria. Laveran's discovery was widely accepted only after five years when Camillo Golgi confirmed the parasite using better microscope and staining technique.[8]

Laveran was a supporter of the

French Academy of Medicine established Ligue corse contre le Paludisme (The League of Corsica to Combat Malaria) with Laveran as its honorary president in 1902.[25]

Leishmaniasis

Laveran came across another protozoan disease,

Madras, India, and with the help of his colleague Félix Mesnil, he named it Piroplasma donovanii.[27][28] However, the scientific name was corrected to Leishmania donovani the same year.[29][30] In 1904, he and M. Cathoire reported the first case of infantile leishmaniasis from Tunisia.[31] He published a treatise on leishmaniasis in 1917.[6]

Trypanosomiasis

Laveran later worked on the

sleeping sickness and animal trypanosomiasis.[32] He described Trypanosoma theileri from cattle in 1902;[33] Trypanosoma nanum in 1905 and Trypanosoma Montgomeryi in 1909, which were later corrected as Trypanosoma congolense, a parasite of nagana in cattle and horses.[34] With Mesnil, he identified Trypanosoma granulosum from European eels in 1902;[35] Trypanoplasma borelli[36] and Trypanosoma raiae from fish in 1902; Trypanosoma danilewskyi from fish in 1904;[36] and published a monograph Trypanosomes and Trypanosomiases (Trypanosomes et Trypanosomiases) in 1904[37] by which more than thirty new species were described.[4]

Awards and honours

Laveran was awarded the Bréant Prize (Prix Bréant) of the French Academy of Sciences in 1889 and the Edward Jenner Medal of the Royal Society of Medicine in 1902 for his discovery of the malarial parasite.[38] He received the Nobel Prize in Physiology or Medicine in 1907 "in recognition of his work on the role played by protozoa in causing diseases."[39] He gave half the Prize for foundation of the Laboratory of Tropical Medicine at the Pasteur Institute.[38] He was honorary fellow of the Royal Society, Royal Society of Edinburgh, Royal Society of Medicine, Pathological Society, Royal Society of Tropical Medicine and Hygiene, and Royal Society for Public Health.[4]

In 1908, he founded the

National Order of the Legion of Honour in 1912. He was Honorary Director of the Pasteur Institute in 1915 on his 70th birthday. His work was commemorated philatelically on a stamp issued by Algeria in 1954.[38]

Recognition

Laveran's name features on the Frieze of the

London School of Hygiene & Tropical Medicine. Twenty-three names of public health and tropical medicine pioneers were chosen to feature on the School building in Keppel Street when it was constructed in 1926.[43]
