Tillie Schloss Pine was born in Pultusk, Poland, on 4 March 1896. She was the daughter of Louis and Rachel Schloss. After the family moved to New York City, she married Nat Pine in 1924. She worked as a children’s author until late in life, and died in 1999 at the age of 102. Pine is recognized for her children’s science and multi-cultural books primarily illustrated by Ezra Jack Keats, which saw printed editions spanning several decades and set in multiple languages. Most of her books follow a similar theme describing traditional cultural processes and techniques and how they are in practice in contemporary sciences. Pine worked closely with fellow author Joseph Levine in producing her works. Pine, Keats, and Levine were all of Jewish background.
