Hartvig

Hertwig and its variants come from a German surname, which in turn derives from two elements: “*harduz / *hardu-” (hard, strong, brave, valiant, powerful) plus “wīg” (fight, battle, fighter, able to fight). In turn, the name means “one who fights a hard battle.” The Hertwig epithelial root sheath (HERS) is a proliferation of epithelial cells located at the cervical loop of the enamel organ in a developing tooth. Oskar Hertwig discovered Hertwig epithelial root in 1874. 1) Oscar Hertwig (1849–1922) was a German zoologist and professor, who also wrote about the theory of evolution circa 1916, over 55 years after Charles Darwin’s book ‘The Origin of Species.’ 2) Hartwig († 1023) was the archbishop of Salzburg from 991 until his death. 3) Hartwig Derenbourg (1844–1908) was a French Orientalist.
