Quick Facts

A Legacy Rooted in Heritage and Ambition

Born into a family that combined entrepreneurial drive and aristocratic heritage, Esther Koplowitz’s upbringing laid the foundation for her later achievements. Her father — Ernesto Koplowitz Sternberg — was a Polish-Jewish entrepreneur who settled in Spain and established a construction enterprise. Her mother — Esther María Romero de Juseu y Armenteros — belonged to old Spanish nobility, carrying titles including the Marchioness of Casa Peñalver. 

Following her father’s untimely death in 1962, Esther and her sister inherited what would eventually become FCC. Educated at a French lyceum and later studying philosophy, she blended a classical formation with keen business instincts. 

Defining moments in Esther Koplowitz’s journey include:

• The inheritance of FCC after her father’s death, placing her in a position of responsibility from a young age.

• Co-managing FCC with her sister from 1989 until 1997. 

• The decisive 1997 acquisition of her sister’s stake for roughly US$ 800 million — a bold move that consolidated her control over the company. 

• The transformation of FCC from a national construction firm into a diversified international conglomerate involved in infrastructure, environmental services, energy, and cement.
