Career
His most famous book is "Handboek der Dierkunde" (1827–1833), translated into German and English (by Professor Clark). He wrote as readily about crocodiles as about butterflies, lancelets and lemurs. January van der Hoeven came from a wealthy family of merchants in Rotterdam.
In 1819 he moved to Leiden.
In 1822 he got a degree in physics and in 1824 in medicine. After a visit to Paris he started working as a family doctor in Rotterdam, but in 1826 he was appointed Professor of Zoology and Mineralogy at the University of Leiden.
By the 19th century it had become impossible to understand and comprehend all knowledge, but Van der Hoeven was a rather old fashioned scientist, (representing the Biedermeier era) and a generalist: neither specializing, nor becoming a theoreticist. In 1834 he started a magazine in Natural History and Physiology.
Van der Hoeven was also involved in education, writing a biology book for pupils in secondary school, although, paradoxically, he was one of the last professors in Leiden to teach in Latin.
In 1860 he asked permission to leave the university. He died in Leiden eight years later. In 1864 he published the Latin biology textbook Philosophia Zoologica.
In 1832 he became correspondent of the Royal Institute and in 1845 member.
