All we know about Esther Levy is that her maiden name was Jacobs, and she was probably a native Philadelphian. Her recipes show strong German influence, with some English touches, which would have been typical of her fellow Pennsylvanians and contemporary cooking experts. Her English is flawless, while her Hebrew seems nonexistent. Some of the Hebrew names in the Jewish Calendar section are almost unrecognizable. At that time, it was not unusual for Orthodox Jewish families to allow their daughters only the minimum education required for a future wife, such as Jewish dietary laws and ritual bathing.
