Carl Linnaeus

Carl Linnaeus (1707-1778) was a brilliant Swedish naturalist and educator who considered all of nature his classroom. Like a botanical prophet, he would lead students on long excursions through woods and fields, reeling off colorful anecdotes and observations on plants, insects and vertebrates. He eventually collected over 14,000 sheets of pressed plants and thousands of insect specimens.


More than two centuries after his death, Linnaeus is most honored for his revolutionary plant and animal naming system of binary Latin nomenclature; one name indicating the genus and the other the species.


It is little wonder that Linnaeus is internationally recognized as the “Father of Botany”.

1753  Publishes Species Plantarum.  Binomial nomenclature for plants begins to be used.




1753  The king of Sweden dubs Linnaeus knight of the Order of the Polar Star.  He was the first civilian in Sweden to receive this honor.

1757  The king grants Linnaeus nobility, but he is not ennobled until 1761 whereupon he takes the name Carl von Linné.


Linné drew a proposal on a coat of arms for the noble family von Linné (left). His proposal was composed of three fields with the colors of nature; black, green and red. Above these fields was an anatomic egg “to denote Nature, which is continued and perpetuated in ovo,” and in the helmet a Linnaea borealis (twinflower). This proposal was rejected and the counter proposed coat of arms was accepted by Linné (right).






1758  Purchases the farms of Hammarby and Savja within 13 km from Uppsala.
