Friedrich August Ludwig Thienemann ( 25 December 1793, Freyburg – 24 June 1858, Dresden) was a German physician and naturalist.
Ludwig Thienemann was the son of Johann August Thienemann (1749–1812) and Johanne Eleonora Friederike née Schreiber (1757–1809). He graduated as a doctor in 1819 and then travelled in Europe for two years, spending thirteen months in Iceland. He published a report on his travel in 1824–1827.
In 1822, he moved to Leipzig, where he taught zoology in the university and he became curator the natural history collections in Dresden (Kustos Naturalien- sammlungen now in Staatliches Museum für Tierkunde Dresden) in 1825. He was the founder of the ornithological newspaper Rhea, whose two numbers appeared in 1846 and in 1849.
He is best remembered for his work in ornithology, in particular research involving avian reproduction. During his career, he amassed a collection of 2000 bird nests and 5000 eggs from 1200 species.[1]
