Sebald Justinus Brugmans (24 March 1763, Franeker – 22 July 1819, Leiden) was a Dutch botanist and physician.
[1] Brugmans studied philosophy, mathematics and physics at the Universities of Franeker and Groningen, earning his doctorate in 1781.
[4] In 1794, when Holland became a refuge for retreating English and Hanoverian armies, he, along with physicians and medical students at Leiden, set up emergency hospital services outside the city.
He repeated this activity in 1799 (for English and Russian forces north of present-day IJmuiden), and in 1809 (bombardment of Vlissingen by the British Navy).
His outstanding work as a physician came to the attention of Louis Bonaparte, as well as to his more famous brother, who promoted him to seventh inspector-general of the Grande Armee.
