Zevi Scharfstein

Zevi Scharfstein (Hebrew: "צבי שרפשטיין") was a prolific Hebrew-language educator, writer, and publishing entrepreneur who authored 423 works in 698 publications during his career. The hosts of a special celebration in Detroit honoring Scharfstein on his seventieth birthday in 1954 described him as "one of the country's leading Jewish educators" whose Hebrew instructional materials were in very wide use in the United States. His 1972 obituary in the "New York Times" attributed a hundred Hebrew textbooks for children to his credit, many of which in the early 1970s were "still considered classics in Hebrew schools." 
Scharfstein was educated as a child by private tutors, and his only official academic degree was an honorary Doctor of Hebrew Letters, awarded by the Jewish Theological Seminary of America. But his prolific career and founding of the Shilo publishing house made him "a teacher of teachers" in the Jewish Diaspora.
Personal life.
Scharfstein was born in the Podolia region of the Russian Empire, in present-day Ukraine. During his childhood, he was strongly influenced by the Haskalah movement, and the movement's emphasis on childhood education and the development of a contemporary Hebrew press both shaped his life and career. After witnessing the violence of pogroms in the region followed by the onset of World War I, Scharfstein immigrated to the United States "without a broken heart." He wrote of "writing new textbooks intended and prepared for the young generation of America."
Career.
Once in the US, he quickly founded a monthly magazine for children, "Shaharut" (Youth). Published by the Bureau of Jewish Education in New York City, "Shaharut"'s original mission was to teach Jewish topics and Hebrew language. After the 1917 Balfour Declaration, the periodical shifted to short stories and articles about Jewish life in Palestine. Scharfstein also joined the Bureau of Jewish Education, founded by noted American Hebraist Samson Benderly in 1910, although Scharfstein was not among the group of proteges known as "the Benderly Boys," Scharfstein believing that Benderly often preferred American-born recruits over immigrants.
In the early 1920s, he founded Shilo Publishing House with the help of his brother, Asher. Controlling his own press and going to market with his own materials freed Scharfstein from the limitations of working within the existing philosophical, pedagogical, and financial power structures of the Hebraist movement. One of his first books was emblematic of his mission: "Sifurei ha-Torah le-yeladim" (Torah Stories for Children). Shilo is still in operation, offering books on "the Hebrew language, studying to read the Haftorah, and the works of Nachmanides," as well as a widely used Siddur for children and Hebrew-English and English-Hebrew dictionaries.
Scharfstein's educational materials, textbooks writing, and curriculum development emphasized stories, pictures, and formats that modeled and extolled a lifestyle that was both Jewish and American. His texbooks featured stories about American Jewish children enjoying American life within the context of Jewish perspectives and values. He also penned biographic sketches and profiles of American Jews to illuminate how they could become both emblematically American and Jewish figures.
Together with his son, Ben-Ami Scharfstein, he authored the first Hebrew textbook for blind English-speaking readers with The Jewish Braille Institute. Ben-Ami went on to teach philosophy at Tel Aviv University.
