His grandfather was, Rabbi Nathan of Trinquetaille, author of "Shaar HiTefisa" His great grandfather was Meir ben Isaac of Carcassonne, author of the "Sefer ha-'Ezer". His family originally came from Florenzia, Spain. The surname Haparchi means "the Florentine" in Hebrew (perach is Hebrew for flower). He is commonly known by the title Kaftor Vaferach taken from the name of his work, the expression being additionally a pun on his surname. When the Jews were expelled from France in 1306, he travelled to Spain and Egypt, and then settled in Eretz Yisrael. He worked as a physician in Bet She'an, where he died in 1355.
Ishtori Haparchi was the author of the first Hebrew book on the geography of Eretz Yisrael  Sefer Kaftor Vaferach (Hebrew: ספר כפתור ופרח (literally "Button and Flower"), written in 1322 and published in Venice in 1549. Kaftor Vaferach ("Book of Button and Flower") is a Hebrew idiom derived from the description of the menorah in the Temple (Exodus 37:17) and means a "work of art". In the context of the book it refers to the lay of the land. Haparchi lists the names of towns and villages in Eretz Yisrael and discusses the topography of land based on first-hand visits to the sites. Modern scholarship has determined that most of the 180 ancient sites he identified were correct, among them Usha, Modi'in and Betar.
