The Alexander family was a prominent Croatian Jewish family from Zagreb. Alexander family ancestors moved to Zagreb from Güssing in Austria. For a century, the family played an important role in the economic and social life of Zagreb. Until 1941 and the establishment of the Independent State of Croatia the Alexanders were a large clan.
The great-grandparents of the Zagreb Alexanders were Samuel and Julija (née Rubin) Alexander, who had five sons and several daughters. Counting all of their deceased and still living members, including also the descendants of the female line, there were 224 Alexanders in seven generations. Many members of the family perished during the Holocaust. Today only one male descendant bears the surname Alexander.
