Kate Seredy (November 10, 1899 – March 7, 1975) was an American writer and illustrator of children's books.

Massee didn't have any illustration work for Seredy, but encouraged her to write about her childhood in Hungary, promising to publish the book for Christmas.

She used many of her impressions and experiences in the story about young Kate, who is sent by her widowed father from Budapest to the country to live with her Uncle and his family.

[1]: 300  The Good Master was named a Newbery Honor book in 1935, a runner-up to Caddie Woodlawn, which Seredy illustrated for Simon and Schuster.

In addition she designed the jacket and endpapers for Young Walter Scott, which was another Newbery runner-up that year.

The book shows the terrible effects of war on ordinary people, especially those who are forced to leave their lands and homes to fight.

She had a unique style, primarily based on drawing, and considered her books "an excuse for making pictures".
