Erwin Schrödinger (1887-1961) remains one of the most recognizable names in 20th-century physics. The Austrian theorist formulated the wave equation that bears his name, shared the 1933 Nobel Prize, and gave the world the thought experiment of the cat that is simultaneously alive and dead until observed; a paradox of quantum mechanics. For decades his private life, an open marriage, multiple affairs, and several children outside the marriage, was treated as the colourful eccentricity of a brilliant man. Then, in late 2021, a different story took hold.
A Irish Times article titled "How Erwin Schrödinger indulged his 'Lolita complex' in Ireland" declared him a "serial abuser whose behaviour fitted the profile of a paedophile." The piece, and the cascade of headlines that followed, drew primarily on Walter Moore's 1989 biography Schrödinger: Life and Thought. Specific claims included a sexual relationship with a 14-year-old tutoring pupil (Ithi Junger), impregnation at 17 followed by a disastrous abortion, other underage involvements, and diary entries that supposedly documented a preference for teenage girls justified by the physicist's "natural genius." Shades of Epstein!
Universities reacted. Trinity College Dublin renamed its Schrödinger Lecture Theatre, cancelled the associated lecture series, and removed his portrait from display. Students at Humboldt University in Berlin pressed for similar changes. The narrative hardened quickly: Schrödinger the genius was also Schrödinger the predator.
New research by Magdalena and Martin Gronau of the Leibniz Centre for Literary and Cultural Research in Berlin has reopened the primary sources. Their 2026 paper in Berichte zur Wissenschaftsgeschichte, examines Schrödinger's own diaries (the Ephemerides), letters from the women involved, and Moore's research notebooks held at Indiana University. The conclusion is unambiguous: the widely circulated allegations "stem from a combination of unprofessional, suggestive biographical writing and poor journalism." They "do not substantiate claims of pedophilic or sexually abusive behaviour by Schrödinger."
Key factual corrections include:
Ithi Junger told Moore, when interviewed in her seventies, that she and Schrödinger became lovers when she was 19. Moore recorded 17; the Irish Times article moved the start of the relationship back to their first meeting at 14. Junger also indicated Schrödinger was distressed by the later abortion because he wanted the child.
Claims involving a 9-year-old girl refer to a childhood acquaintance when Schrödinger himself was about 11.
A poem written for a girl described as 12 (actually 13) was, according to her sister, a piece of imperfect English urging her to clean her nails.
A later allegation of rape involving a 26-year-old woman rests on "purely speculative suspicions with no demonstrable historical basis." Diary entries record that she preferred older men and initiated physical contact; they later had a daughter together.
Schrödinger's sexual life was active and non-monogamous by mutual arrangement with his wife Annemarie. Partners were often younger; he fathered three daughters with women other than his wife. That pattern can be judged distasteful by contemporary standards, but the diaries and correspondence contain no evidence of pre-pubescent attraction or sexual abuse.
Moore struggled with the sources. Schrödinger wrote in four languages and multiple scripts (Latin cursive, Kurrent, Gabelsberger shorthand, Greek characters). Much of the material Moore could not read; gaps were filled with inference. Selective quotation turned private reflections, sometimes about household tensions in wartime exile, into apparent confessions. The phrase "poor things," for example, appears in context about the women sharing his constrained Dublin household, not about exploited minors.
Unlike the famous thought experiment, Schrödinger's public reputation was treated as definitively collapsed once the accusation was published. Institutions acted on secondary summaries of a decades-old biography rather than waiting for, or demanding, access to the primary record. The diaries had been restricted by the family; once examined by researchers competent in the scripts and languages, the picture changed.
The episode illustrates how quickly a historical figure's name can be recast when journalistic amplification meets institutional caution. It also shows the corrective power of returning to sources. Schrödinger's personal life was complicated, often involving significant age gaps with adult partners, and he lived in an open marriage. Those facts are visible in the record. The stronger claims, of paedophilia, serial grooming of children, and systematic abuse, are not supported by the diaries, the women's accounts, or Moore's own interview notes.
Five years after the initial wave of coverage, the institutional renamings remain in place. The scientific contributions are unchanged. The difference is that the primary evidence has now been read.
