German philologist and folklorist Jakob Ludwig Karl Grimm in 1822 formulated Grimm's Law, the basis for much of modern comparative linguistics. With his brother Wilhelm Karl Grimm (1786-1859), he collected Germanic folk tales and published them as Grimm's Fairy Tales (1812-1815). Indo-European stop consonants, represented in Germanic, underwent the regular changes that Grimm's Law describes; this law essentially states that Indo-European p shifted to Germanic f, t shifted to th, and k shifted to h. Indo-European b shifted to Germanic p, d shifted to t, and g shifted to k. Indo-European bh shifted to Germanic b, dh shifted to d, and gh shifted to g. This jurist and mythologist also authored the monumental German Dictionary and his Deutsche Mythologie . Adapted from Wikipedia.

Jack David Zipes is a retired Professor of German at the University of Minnesota. He has published and lectured extensively on the subject of fairy tales, their linguistic roots, and argued that they have a "socialization function". According to Zipes, fairy tales "serve a meaningful social function, not just for compensation but for revelation: the worlds projected by the best of our fairy tales reveal the gaps between truth and falsehood in our immediate society." His arguments are avowedly based on the neo-Marxist critical theory of the Frankfurt School. Zipes enjoys using droll titles for his works like Don't Bet on the Prince and The Trials and Tribulations of Little Red Ridinghood. He completed a PhD in comparative literature at Columbia University. Zipes taught at various institutions before heading German language studies at the University of Minnesota. He has retranslation of the complete fairy tales of the Brothers Grimm.
