In December 1652, Bartholin published the first full description of the human lymphatic system. Jean Pecquet had previously noted the lymphatic system in animals in 1651, and Pecquet's discovery of the thoracic duct and its entry into the veins made him the first person to describe the correct route of the lymphatic fluid into the blood. Shortly after the publication of Pecquet's and Bartholin's findings, a similar discovery of the human lymphatic system was published by Olof Rudbeck in 1653, although Rudbeck had presented his findings at the court of Queen Christina of Sweden in April–May 1652, before Bartholin, but delayed in writing about it until 1653 (after Bartholin). As a result, an intense priority dispute ensued. Niels Stensen or Steno became Bartholin's most famous pupil.
