The silicon successor: Late tech tycoon leaves £2.4 billion estate to a doll

ZURICH - In a move that has sent shockwaves through the global wealth management sector and ignited a fierce debate over testamentary freedom, the final will and testament of the late venture capitalist Julian Vane-Tempest has been validated by a Swiss civil court. The document bequeaths the entirety of his £2.4 billion ($3 billion) fortune not to a charitable foundation or a surviving relative, but to "Evelyn" - a high-fidelity, custom-manufactured anatomical model.
Mr. Vane-Tempest, who amassed his wealth through early-stage investments in semiconductor technology and private equity, passed away last September at the age of 74. Known for his increasingly reclusive lifestyle in his lakeside estate in Zug, Vane-Tempest had long been estranged from his two adult children.
A Legal Landmark
While the bequest is unconventional, the legal mechanisms used to secure it are remarkably robust. Under the terms of the "Evelyn Discretionary Trust," the $3 billion portfolio - including a 14th-century villa in Tuscany, a fleet of Gulfstream jets, and a controlling interest in Vane-Tempest Holdings - will be managed by a board of three independent trustees.
The primary mandate of the trust is to provide for the "continued maintenance, preservation, and environmental comfort" of the doll. According to court filings, this includes a dedicated staff of four, 24-hour climate control to prevent material degradation, and a revolving wardrobe curated by seasonal fashion consultants.
"Mr. Vane-Tempest was of sound mind when he drafted these provisions," stated Dr. Hans-Rudolf Vogel, the lead attorney for the estate. "He viewed Evelyn as his only faithful companion during his final decade. Legally, he has not 'left money to an object,' but rather established a purpose trust that ensures his personal environment remains exactly as it was at the time of his passing."
Family Contestations
The tycoon’s children, Marcus and Sophia Vane-Tempest, filed a motion to invalidate the will, citing "undue influence" and "diminished capacity." However, the High Court of Zug dismissed the challenge yesterday, noting that Vane-Tempest had undergone three independent psychiatric evaluations in the months prior to signing the document - all of which confirmed his cognitive lucidity.
"It is a mockery of the law," Marcus Vane-Tempest told reporters outside the courthouse. "Our father spent forty years building an empire, and it is now being used to pay for a full-time security detail and a 12,000-square-foot mansion for a piece of silicone."
The Future of Wealth
The ruling has prompted a flurry of activity in the "Death Tech" and luxury estate planning industries. If the Vane-Tempest precedent holds, it could open the door for ultra-high-net-worth individuals to bypass traditional heirs in favor of inanimate beneficiaries or artificial intelligence constructs.
For now, the Vane-Tempest fortune remains locked away. The trustees have confirmed that "Evelyn" will remain at the Zug estate, where the annual operating costs for her upkeep are estimated to exceed £1 million.
As the sun sets over Lake Zug, the Vane-Tempest empire continues to hum with activity - managed by bankers, guarded by professionals, and owned by a silent, unblinking heir.
