{"title":"‘Nico’—A lone voyager in Strange Seas","authors":"David S. Baldwin","doi":"10.1002/hup.2859","DOIUrl":"10.1002/hup.2859","url":null,"abstract":"<p>Christa Päffgen died in a corridor waiting for a hospital bed during the evening of July 18, 1988. She was 49 years old. Contemporaneous accounts state that she had cycled away from home in searing midday heat for distant downtown Ibiza hoping to buy hashish. She was found by strangers at a roadside that afternoon, unable to talk. A first hospital turned Christa away as a ‘vagrant junkie’; a second declined assessment because she had no health insurance; a third refused admission as she was an ‘old hippie’. Staff in a fourth hospital admitted her and ultimately diagnosed a cerebral haemorrhage, but could not insert a needle into her tired old veins: though she was undergoing methadone replacement therapy, she had previously been addicted to heroin for over 15 years.</p><p>Christa was more commonly known as ‘Nico’, and had been a model, actress, singer-songwriter and musician. She sang on four tracks of <i>The Velvet Underground and Nico (1967)</i>—including ‘Femme Fatale’ and ‘All Tomorrow's Parties'—with an austere, unornamented, deep contralto voice. Subsequent solo albums pushed against musical and emotional boundaries; and are considered unlistenable by some, ground-breaking by others. <i>The Marble Index</i> (1968),1 with its sorrowful plainsong, bleak swirling harmonium, and distorted viola gradually became regarded as an avant-garde classic. Nico associated with a <i>Who's Who</i> of male rock stars of the 1960/70s. Men were captivated by her beauty but threatened by her often scornful disdain: with notable exceptions, most treated her carelessly. In subsequent decades, she was no longer denigrated as a mere Muse or Mannequin, but instead valued as an exceptional though troubled musical visionary. But opiate addiction eroded her output remorselessly, and she spent most of her final years at the margins of the New Wave music scene, living precariously in Prestwich and Salford.</p><p>The relevance of the decline of ‘Nico’ to the concerns of psychopharmacologists and psychiatrists might seem somewhat tenuous: that is, before considering her experience of childhood trauma in wartime Germany, the recurring toll of abusive intimate relationships, and stigmatised attitudes towards drug addiction. The military call-up of her father contributed to her temporary placement in the largest orphanage in Europe, which was run according to mixed arch-Catholic and Nazi ideology. Her father subsequently died from war injuries before Christa could see him again. As a teenager she had to provide evidence at a court-martial, after being raped by a soldier of the post-war American occupying forces. As ‘Nico’, she was manipulated by a succession of men who exploited her allure, belittled her intelligence, and demeaned her artistry.</p><p>Nico showed the persistent detachment of recurrently traumatised individuals long before her preoccupying persistent concern about securing the next ‘fix’.

This made his numerous achievements in psychopharmacology - carried out of necessity on top of his NHS work in his own time—particularly remarkable. In fact, coming from a working-class family in a Welsh mining village, Guy was the first member of his family to have full experience of secondary school, let alone a university education.</p><p>Admiration for the family GP prompted Guy to opt for medicine, and positive experiences of work with psychiatric patients as a medical student led him later to specialise in psychiatry in Manchester where he obtained his DPM in 1964. However, it was a chance encounter with Linford Rees that led Guy into the field of psychopharmacology. Rees knew that the famous American psychopharmacologist, Nathan Kline, was in London recruiting psychiatrists to assist in his drug development programme and arranged a meeting between them.</p><p>The meeting with Kline resulted in Guy spending three key years in the United States where he learned about laboratory and clinical aspects of psychopharmacology, the latter in collaboration with George Simpson involving clinical trials of antipsychotic drugs in the ‘Early Clinical Drug Assessment Unit (ECDU)’ at the Rockland Research Institute, New York. This was an exciting time for psychotropic drug development with the antipsychotic effects of chlorpromazine having been demonstrated just a few years earlier. At ECDU, Guy studied the clinical effects of several newer potential antipsychotic drugs, including thioxanthenes and butyrophenones. The experience gained here was important to Guy, when after returning to the UK, he carried out investigations of the therapeutic and adverse effects of other new antipsychotic agents such as remoxipride and sulpiride. Characteristically in this work he would devise his own protocols and be responsible personally for patient recruitment and clinical care.</p><p>Guy's contribution to the psychopharmacology of antidepressant drug treatment was particularly notable and showed his gift for collaboration with general medical and psychiatrist colleagues as well as his ability to identify issues important to clinicians and their patients. For example, recognising the problematic pro-convulsant effects of tricyclic antidepressants, Guy carried out studies with Michael Sedgwick, a Professor of Neurophysiology, looking at the effect on seizure threshold of alternative antidepressant agents such as mianserin and paroxetine. Similarly, with physician-pharmacologist Derek Waller, he compared the effects of antidepressants on cardiac conduction and assessed the consequences of lithium treatment on renal function.</p><p>Guy's combination of scientific insight and clinical acumen led him to be a frequent editorial writer for journals such as the British Medical Journal (BMJ).
