Excerpts:
...Mrs. Wronker was a devout typophile — she was a founding member of the Society of Scribes in New York — whose fascination with the shape and form of letters found creative expression on hundreds of book jackets between the 1940s and ’60s. They included “Einstein: A Pictorial Biography” (1955), by William Cahn; “Jolly Jingles for the Jewish Child” (1947), by Ben Aronin; and “The Adventures of Ellery Queen: Eleven Problems in Crime Deduction" (1947).
She often also provided the illustrations inside the books.
Her love of Judaism — a reflection of her heritage more than religious passion — found artistic expression in her Hebrew calligraphy, which appeared in fine-art books and magazines. Her scholarly knowledge of the field led her to record a video about the history of the Hebrew alphabet...
...Lili Cassel was born in Berlin on May 5, 1924, to Dr. Josef and Edith (Basch) Cassel. Her father was a dermatologist, her mother a homemaker.
Lili was 14 when Nazis violently attacked Jews and their property throughout Germany, Austria and parts of what was then Czechoslovakia on the night of Nov. 9-10, 1938, which came to be known as Kristallnacht. The pogroms prompted her parents to send her and her sister, Eve, to a boarding school in Haslemere, Surrey, about 45 miles southwest of London.
Dr. Cassel eventually followed his daughters, living in a rented room in London; his wife stayed in Germany and Belgium for another 18 months. The family reunited in 1940 and emigrated to the United States...
