Explainer-How tycoon and Chrysler Building owner Benko lost grip of his empire
Rene Benko, one of Europe's most prominent property tycoons, on Wednesday relinquished the chairmanship of Signa Holding, the real estate empire he founded, amid an investor revolt and dimming prospects for the sector.

Born in 1977 in Innsbruck, Rene Benko dropped out of school and began by turning attics into apartments.
