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

Polish rebellion of 1831 he took the position of staff surgeon at the Alexander-Hospital in Warsaw, lending support to the beleaguered Polish partisans.[6] 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.[7]

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.[8] 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.[9]


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.[10] This union produced three children, all of whom died young:

  • Gottlob Wilhelm Richard Paul (13 April 1834 - 9 March 1835)
  • Louise Marie Anna (5 January 1836 - 29 May 1840)
  • Johanna Caroline Marie (25 October 1837 - 1 June 1840)

Louis Pfeiffer married his second wife, Wilhelmine Friederike (née Wagner, 10 April 1823 - 26 June 1900), on October 9, 1842.[11] 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."

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.[17]

Ludwig Carl Georg Pfeiffer died of a lung infection on October 2, 1877.[18]
