Because they had no father, Jacob and Wilhelm grew close to each other. They attended the University of Marburg, where their law professor introduced them to philology -- the study of language in historical texts. Because of their family's poverty, Jacob and Wilhelm were excluded from the school's social life -- which drove them to pursue their studies more energetically.Share
