    Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botanist and conchologist.

    Early life, Education & Medical Career

    Louis Pfeiffer was born in Cassel, the eldest son of the jurist Burkhard Wilhelm Pfeiffer and his wife Louise (née Harnier). Pfeiffer received his primary education in the Cassel Lyceum, where he distinguished himself academically, and by the age of fifteen was already at the top of his class. In 1820, political tensions forced his father to relocate the family to Lübeck, but Louis continued to excel, reaching the top of his class there as well. At the age of sixteen, Pfeiffer entered into university to study medicine, first at the University of Göttingen, and finally at the University of Marburg, where he studied under such prominent scientists as Georg Wilhelm Franz Wenderoth and Ernst Daniel August Bartels, graduating in 1825. He spent the next year in Paris and Berlin, continuing his education, and returned to Cassel in 1826, where he entered into general practice and obstetrics.[1] During his short interlude in Kassel, Pfeiffer was engaged in many artistic pursuits, particularly musical ones, and his lyric baritone was remarked on often by his brother Carl's friend (and later, his brother-in-law) Louis Spohr. The Pfeiffer brothers performed often with Spohr and his singing groups, even pairing up to perform in the opera of German: Pietro von Abano that Carl had adapted and Spohr composed. At the outbreak of Polish rebellion of 1831 he took the position of staff surgeon at the Alexander-Hospital in Warsaw, lending support to the beleaguered Polish partisans. In addition to the war-wounded he treated at the hospital, he also took a special interest in caring for the many thousands who were stricken with cholera as a result of the upheaval cased by the conflict. In September 1831, the Polish rebels were forced to capitulate to the overwhelming Russian military force, but Pfeiffer had developed such a close feeling of kinship and support for the Poles that he refused to stay on and work with the Russians.

    Louis's return to Cassel was overshadowed, however, by the untimely death of his elder brother Carl, who succumbed to the very same cholera that Louis worked so hard to fight in Poland. As a result of the outbreak of cholera across Prussia, Louis was kept in quarantine before he could enter Cassel, which prolonged his and his family's grief, until he was finally permitted to return home and bury his brother. Upon his return home, Pfeiffer undertook his first publication, a personal recollection of his experience entitled Erfahrungen über die Cholera, gesammelt in dem Hospital zu Warschau im Sommer 1831.

    Family

    Louis Pfeiffer was married twice. His first marriage was to Luise Philippine (née Nathusius, 2 September 1811 – 18 September 1891), daughter of the industrialist Johann Gottlob Nathusius. They were married on May 19, 1832, and divorced in 1841. This union produced three children, all of whom died young:

    Louis Pfeiffer married his second wife, Wilhelmine Friederike (née Wagner, 10 April 1823 - 26 June 1900), on October 9, 1842. Their marriage lasted until Pfeiffer's death, and produced six children:

    Scientific Career & Later Life

    After his return to Cassel and his marriage, as well as the death of his eldest son, Pfeiffer had grown unhappy with his medical practice, finding the state of medical science at the time insufficient for his intellectual needs, and gave it up to focus on scientific studies and literary works, particularly in the fields of botany and conchology. His first scientific work, published in 1837, was a book cataloging and describing the various cactus species used in German gardens. It was well received, and as a result, he became known as "Kaktus-Pfeiffer". In 1839, Pfeiffer was sent to Cuba with Johannes Gundlach and Eduard Otto in order to study the flora, fauna, and natural history of the West Indies, and it was this experience that piqued his interest in mollusks, conchology, and malacology. The group explored other islands in the Caribbean, but the experience had to come to and end, as the extended absence from home, which coincided with the deaths of his two remaining children, caused a rift between Pfeiffer and his wife that led to their divorce almost immediately upon his return to Europe in 1841. After remarrying, Pfeiffer adopted a sedentary and academic lifestyle, focusing his energy on the specimens and data he had collected in Cuba, classifying more than 20 new genera and species of mollusks. He proved to be a prolific publisher, and expanded his interest from conchology to the botany that had been his first love, writing several treatises on the nature flora of Hesse and its surrounding regions, coedited with the esteemed botanist Johann Cassebeer. Since 1836, Pfeiffer had been a member of the Cassel Society for Natural history, and from 1837 a member of the German National Academy of Sciences Leopoldina and the Regensburg Botanical Society. In 1868, Pfeiffer and his colleagues Wilhelm Kobelt and Karl Ludwig Fridolin von Sandberger added a further membership with the founding of the German Malacozoological Society. In 1871, Pfeiffer's already failing health was dealt a blow with the death of his youngest son Wilhelm, only 19 years old, on the battlefield in France, one of innumerable casualties of the Franco-Prussian War. In 1874, the increasingly frail Louis Pfeiffer undertook a two-month journey to Catalonia, where his eldest son Hermann was in business as a merchant, and the trip appears to have been an uneventful one, despite conceding directly with the coup d'état that toppled the First Spanish Republic. In 1875, on the 50th anniversary of his doctorate, and the 70th anniversary of his birth, he was surprised by the medical faculty of the University of Marburg, who renewed his doctoral credentials. In addition to the renewal of his medical doctorate, he was also given an honorary doctorate in philosophy by the philosophy faculty, honoring a life spent in pursuit of knowledge. Pfeiffer was also awarded the Prussian Order of the Red Eagle, 4th class, in gratitude for scientific service to the nation. Ludwig Carl Georg Pfeiffer died of a lung infection on October 2, 1877.
