not use surnames. They, too, were required to adopt surnames during the 19th century. Medieval France In medieval France the use of Biblical names appears to have been more extended, judging by the elaborate lists at the end of Gross's Gallia Judaica. True surnames occurred, especially in the south, like Farissol, Bonet, Barron, Lafitte; but as a rule local designations were popular, such as "Samson of Sens", etc. Israel Many immigrants to modern Israel change their names to Hebrew names, to erase remnants of exiled life still surviving in family names from other languages. This phenomenon is especially common among Ashkenazic Jewish immigrants to Israel, because most of their surnames were taken recently, and many were imposed by authorities in Europe as a replacement for the traditional Hebrew patronymic form. A popular form to create a new family name using Jewish patronymics sometimes related to poetic Zionist themes, such as ben Ami ("son of my people"), or ben Artzi ("son of my country"), and sometimes related to the Israeli landscape, such as bar Ilan ("son of the trees"). Others have created Hebrew names based on phonetic similarity with their original family name: Golda Meyersohn became Golda Meir. Another famous person who used a false patronymic was the first Israeli Prime Minister, David Ben-Gurion, whose original family name was Grünberg,"green mountain" in German, but adopted the name "Ben-Gurion" ("son of the lion cub"), not "Ben-Avigdor" (his father's name). Iran Most of the Jews in Iran had no permanent surnames before Reza Shah. After surnames became mandatory, many Persian Jews employed job related names as their surnames. Many Jews worked in non-Muslim professions like goldsmith, silversmith, dealers of coins, money changing and seller of spirits. Others engaged in medicine, silk manufacturing and weaving, locksmith, tailors, shoe makers, merchants of second hand items. Many other Jews were engaged in jewelry trading, opium and wine manufacturing, musicians, dancers, scavengers, peddlers and other professions that were generally deemed non-respectful. Many Jews adopted these professions as their surnames, such as Abrishami (silk maker), Almasi (diamond maker), Boloorian (crystal maker), Dehghan (wealthy farmer), Fallah (farmer), Zarrinkoob, Javaherian, Gohari (gold seller), Noghrehforosh (silversmith), Mesforosh (coppersmith), Sarraf, Sarrafan, Sarraf Nezhad, Banki (money changer), Zargar, Zarshenas (goldsmith), Hakakian or Hakkakian (connected with raw material, finished product or implements associated with that trade) for example Roya Hakakian. Jews in Iran also employed the son of or daughter of patronymics, using Persian
