Theodor Heinrich Hermann von Heldreich was a German botanist, who was born on 3 March 1822 in Dresden (the son of Conrad Friedrich Robert Heldreich and Amalia Charlotte Humbold) and died on 7 September 1902 in Athens.
Scion of an old aristocratic family, he initially studied philosophy. A love of botany, however, took him to Montpelier in 1837 to study under Professor Dunal. He later completed his botanical education in Geneva (1838-1842). His first botanical expedition was to Sicily, after which he published his first work “Tre nuove specie di piante scoverte nella Sicilia.” From 1843 to 1848 he travelled extensively throughout Italy, Greece, Asia Minor and Crete. During 1849 and 1850 he lived in England, and then for a year in Paris where he served as curator of P. Barker Webb’s herbarium. In 1851 he settled permanently in Greece, where he carried out rigorous botanical investigations, publishing thirteen volumes of the “Herbarium Graecum Normale” between 1856 and 1896. In Greece he served as director of the botanical gardens for over 50 years, as well as director of the natural history museum, where in addition to the department of botany he helped create departments of zoology and paleontology. Between 1880 and 1883 he taught natural history to the children of the royal family.
In addition to a great number of monographs published in reputable journals in Greece and abroad, he also published scholarly works in Greek, Latin, German, Italian and French, including:
In 1880 he published a romance entitled “Mussinitza,” in 1887 “A Sketch on the Death of Professor of Botany and Poet Theodoros G. Orfanides,” in 1887 “The Flower, from a Historical, Natural and Aesthetic Viewpoint,” and in 1889 “The Lily, Examined from a Fictional and Historical Perspective.” Heldreich discovered seven new genera and 700 new species of plants, 70 of which bear his name.
In 1855 Theodor von Heldreich married Sofia, daughter of I. Katakouzinos and granddaughter of Greek scholar and patriot, Konstantinos Koumas. With Sofia he had two daughters, Karolina, who married Gangolf von Kieseritzky, Curator of Antiquities at the Imperial Hermitage Museum in St. Petersburg, and Ioanna, who married Mark Mindler, attorney and head of the stenographer’s office of the Greek Parliament. Theodor von Heldreich was a good friend of Charles Darwin.
