Live and act

Christian Eduard Langethal was the son of the master shoemaker Christoph Heinrich Langethal from Kranichfeld, who settled in Erfurt after his years of traveling. His mother died in 1809.

Christian Eduard Langethal is the younger brother of the pedagogue Heinrich Langethal . Another brother, Gottlieb Langenthal, learned the shoemaking trade and worked as a master shoemaker in Erfurt. Through the mediation of his brother Heinrich, who was a close friend of Friedrich Fröbel and later worked with him as an educator and teacher, Christian Eduard Langethal became a pupil at Fröbel's educational institution in Keilhau from 1817 .

Langethal left Keilhau in 1827 and went to Jena to study natural sciences. During his studies he became a member of the Jena fraternity in 1827 and of the Arminia Jena fraternity in 1830 . As a member of the fraternities, he was involved in their persecution and therefore sentenced to life imprisonment, from which he was released after just one year. He continued his studies and in 1831 obtained a doctorate in philosophy from the University of Jena . In 1835 he went with his teacher, Professor Friedrich Gottlob Schulze , to the Agricultural Academy Eldena near Greifswald , which had recently been founded, and gave lectures on natural history there . Together with Schulze, he returned to the University of Jena in 1839 and was appointed professor of agricultural botany and plant production.

Langethal's teaching was severely affected by his hearing loss. All the more intensively he worked as a specialist author in the fields of agricultural botany and agricultural history . His most successful work was the textbook of agricultural botany for practical farmers and friends of the plant kingdom . It was published in several sub-volumes (1841 to 1845) and was published five times, most recently in 1876 under the title Handbook of Agricultural Plant Science and Plant Cultivation . For decades it was considered a standard work for agricultural scientists, botanists and farmers. The well-founded description of the most important agricultural crops, vegetable and medicinal plants as well as the fruit and forest trees belonging to the field of agriculture served as a model for subsequent textbook authors.

Langethal made a name for himself as an agricultural historian with his history of German agriculture, which was published in four volumes from 1847 to 1856 . The fourth volume, which covers the period between 1618 and 1800, is a valuable source of information, especially for the early history of crop science. The Paul Parey publishing house in Berlin later had the entire work reworked. In the series of the “Thaer-Bibliothek” further editions appeared after 1880 under the same title.

Langethal was the editor of an improved edition of the German Fruit Cabinet , which appeared in 65 deliveries between 1853 and 1864. Each delivery included the description of 10 types of fruit, which were supplemented by elaborately colored images.
