Herman Boerhaave, Dutch botanist and physician (born 1668)

Herman Boerhaave was a Dutch chemist, botanist, Christian humanist, and physician. He is sometimes regarded as the founder of clinical teaching and of the modern academic hospital along with Venetian physician Santorio Santorio (1561–1636). Boerhaave introduced the quantitative approach into medicine, along with his pupil Albrecht von Haller (1708–1777). He was the first to isolate the chemical urea from urine. He was the first physician to put thermometer measurements to clinical practice. His motto was Simplex veri sigillum: 'Simplicity is the sign of the truth'. He is often hailed as the "Dutch Hippocrates".
