Origins of the Lobotomy
The modern lobotomy emerged in the late 1930s from neuropsychiatric experiments aimed at curbing severe agitation and psychosis when other treatments failed. Its foundational premise, disrupting dense neural circuits to alter severe psychiatric symptoms, was driven by observations of frontal lobe function and case reports from psychosurgery. The first systematic transorbital approaches were developed in Portugal before spreading internationally, blending neuroanatomy, psychiatric nosology, and therapeutic urgency in asylums across Europe and the Americas.
António Egas Moniz: The Pioneering Figure
Portuguese neurologist and Nobel laureate António Egas Moniz is widely credited with initiating the leucotomy that became the modern lobotomy. Working at the University of Lisbon, he introduced the procedure in 1935 after studying frontal lobe pathways and collaborating with neurosurgeon Pedro Almeida Lima. By 1936, he reported modest improvements in select agitated and psychotic patients, establishing the conceptual basis and surgical protocol that others would rapidly modify.
The First Patients
Moniz’s early cases targeted individuals with aggressive agitation and treatment-resistant symptoms. These initial interventions used subcortical knife cuts to interrupt prefrontal white matter, guided by anatomical assumptions of the era. While outcomes were mixed, the reported reductions in distress and impulsivity drew attention from clinicians in asylum settings, catalyzing further refinements and international interest.
Walter Freeman and the Transorbital Approach
American neurologist and psychiatrist Walter Freeman adapted Moniz’s concept into the transorbital lobotomy, popularized from 1936 onward. Freeman, collaborating initially with neurosurgeon James Watts, sought a simpler, faster method that could be performed outside academic centers. Using an orbitoclast inserted through the eye socket, he severed prefrontal connections, promoting outpatient or ward-based procedures with reduced operating time.
Spread Across the United States
Freeman’s technique lowered technical barriers, enabling psychiatrists without extensive neurosurgical training to perform lobotomies. Institutions embraced the procedure for agitated, violent, or withdrawn patients, citing rapid behavioral control. Training sessions and manuals proliferated, expanding the practice into state hospitals and private facilities across North America and beyond.
Technical Methods and Procedural Variants
Early psychosurgery included direct cortical lesions via knife, hook, or cautery, targeting the prefrontal white matter and anterior cingulate networks. Variants combined subcortical cuts with surface transections in an effort to maximize symptom relief while minimizing mortality. Over time, clinicians stratified candidates by diagnosis, agitation level, and perceived prognosis, though objective measures remained limited.

Outcomes, Complications, and Clinical Impact
Reported outcomes varied: some patients showed reduced agitation and improved institutional functioning, while many experienced flattened affect, apathy, and cognitive changes. Mortality and significant morbidity, including seizures and infections, were documented. Despite limited rigorous evaluation, lobotomy became widely adopted in the mid-20th century, influencing psychiatric practice, institutional policies, and public perceptions of psychosurgery.
Decline and Legacy
The introduction of antipsychotic medications in the 1950s and growing awareness of severe adverse effects led to sharp declines in lobotomy use. Ethical scrutiny increased as evidence of enduring cognitive and emotional deficits mounted. Today, the procedure is largely historical, though it informs contemporary debates about neuromodulation, informed consent, and the treatment of severe mental illness. Moniz and Freeman remain central figures in its origin and diffusion, reflecting both medical innovation and its cautionary consequences.
Early psychosurgery research emphasized disruption of frontal networks implicated in emotion and impulse regulation. Historical analyses highlight shifts from anatomical hypotheses to pragmatic asylum practices. The legacy of lobotomy underscores enduring challenges in balancing risk, benefit, and ethical responsibility in psychiatry.

Modern Context and References
Contemporary psychosurgery focuses on highly targeted neuromodulation with rigorous safety and ethics oversight, a direct response in part to the harms observed during the lobotomy era. Historical literature, institutional records, and Nobel archives provide primary sources for studying the origins and propagation of lobotomy. Clinicians and historians emphasize informed consent, empirical outcomes, and patient autonomy as enduring lessons from this chapter in psychiatric history.
Understanding who started the lobotomy and how the practice evolved clarifies the intersection of neuroscience, psychiatry, and ethics. The transition from pioneering curiosity to widespread intervention and eventual restraint illustrates key patterns in medical innovation, risk, and regulation that remain relevant for new surgical and neuromodulation technologies today.
