Matthias de l'Obel

Mathias de l'Obel, Mathias de Lobel or Matthaeus Lobelius (1538 – 3 March 1616) was a Flemish physician and plant enthusiast who was born in Lille, Flanders, in what is now Hauts-de-France, France, and died at Highgate, London, England. He studied at the University of Montpellier and practiced medicine in the Low Countries and England, including positions as personal physicians to two monarchs. A member of the sixteenth-century Flemish School of Botany, he wrote a series of major treatises on plants in both Latin and Dutch. He was the first botanist to appreciate the distinction between monocotyledons and dicotyledons. The plant genus Lobelia is named after him, as is Lobel's maple Acer lobelii.
