Harriet Ziefert grew up in North Bergen, New Jersey, where she attended the local schools. She graduated from Smith College, then received a Masters degree in Education from New York University. For many years, Ziefert was an elementary school teacher. She taught most grades from kindergarten to fifth grade. "I liked it," she said, but she stopped teaching when she had her own sons. When her children were older, Ziefert wanted "a bigger arena" for her work. She went to work at a publishing company, Scholastic in New York City, developing materials for teacher's guides for kindergarten language arts and social studies programs. "About twelve years ago," says Ziefert in a 1995 interview, "I tried to get a job as an editor, but no one would hire me as a trade editor. So I decided to write my own books." Since then, she has written several hundred books, mostly picture books and easy-to-read books. "I write books very quickly," she says, "in about twelve hours. I rewrite them three times over three days, and then they're done." She writes about twenty books a year.

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.
