Frequently asked questions
What is the relationship between the Schlumberger family and SLB, the public company?
The family's fortune originated from the company now known as SLB, which they founded in 1926. While descendants retain some shareholding, the family's direct operational control of SLB has diminished over generations. Today, the family's investment vehicles operate independently from the public company, with their own portfolios of real estate, private equity, and cultural assets.
What role do the Seydoux heirs play in the Schlumberger family ecosystem?
The Seydoux family, heirs to the Schlumberger fortune through marriage, are prominent in French cinema. They hold controlling interests in Pathé and Gaumont, two of Europe's oldest film studios. This branch of the family operates largely within the media and entertainment sector, distinct from the real-asset focus of the Primat line or the cultural philanthropy of the de Menils.
Which sectors does the Schlumberger family's capital explicitly target or avoid?
The family's known investments concentrate on tangible hard assets — hospitality real estate (Domaine des Etangs, Luttrellstown Castle, Primland Resort), European industrial holdings, and cultural assets. There is no public evidence of significant venture capital or technology startup exposure. The investment posture prioritizes multi-generational capital preservation over high-growth speculation.
