Public Biography
Greta Einstein-Haas is the great-great-granddaughter of Albert Einstein and the plaintiff in what legal analysts have described as the broadest intellectual property claim in the history of American jurisprudence. In April 2026, she filed suit in the U.S. District Court for the District of New Jersey against approximately 40,000 physicists, alleging systematic plagiarism of her ancestor’s foundational contributions to the field.
Ms. Einstein-Haas is an interior designer based in Montclair, New Jersey, where she operates Haas Interiors, a residential design firm specializing in mid-century modern renovations. She holds a Bachelor of Fine Arts from the Rhode Island School of Design and a certificate in kitchen and bath design from the National Kitchen & Bath Association. She has no formal training in physics, law, or intellectual property, a combination of absences she considers irrelevant to the merits of her case.
She is the daughter of Thomas Einstein-Haas, a retired orthodontist, and the granddaughter of Eduard Einstein-Haas, a mechanical engineer in Zurich who, according to family lore, once asked his grandfather to explain relativity and received a postcard that read, “It depends on where you are sitting.” The postcard has not been located.
Ms. Einstein-Haas said she became aware of the scope of Einstein’s uncredited influence during a home renovation project in 2024, when a contractor mentioned that GPS satellites rely on general relativity. “That was the moment,” she told reporters. “I realized that the entire modern world is running on my family’s work, and nobody thought to pick up the phone.”
She is represented by Morris Blatt of Blatt, Grunewald & Peck.
