ugly]—a man of keen insight, exquisite taste and wide erudition [...] frank and open-hearted"—ending his public praise with the wish of Mendelssohn recognizing, "together with Plato and Moses... the crucified glory of Christ." When, in 1775 the Swiss-German Jews, faced with the threat of expulsion, turned to Mendelssohn and asked him to intervene on their behalf with "his friend" Lavater, Lavater, after receiving Mendelssohn's letter, promptly and effectively secured their stay. Illness In March 1771 Mendelssohn's health deteriorated so badly that Marcus Elieser Bloch, his doctor, decided his patient had to give up philosophy, at least temporarily. After a short and restless sleep one evening, Mendelssohn found himself incapable of moving and had the feeling of something lashing his neck with fiery rods, his heart was palpitating and he was in an extreme anxiety, yet fully conscious. This spell was then broken suddenly by some external stimulation. Attacks of this kind recurred. The cause of his disease was ascribed to the mental stress due to his theological controversy with Lavater. However, this sort of attack, in milder form, had presumably occurred many years earlier. Bloch diagnosed the disease as due to 'congestion of blood in the brain' (a meaningless diagnosis in modern medical practice as such congestion is anatomically impossible), and after some controversy this diagnosis was also accepted by the famous Hanoverian court physician, Johann Georg Ritter von Zimmermann, an admirer of Mendelssohn. In retrospect, his illness might be diagnosed as a heart-rhythm-problem (such as atrial fibrillation) and/or a mild form of familial dysautonomia, a hereditary disease of Ashkenazi Jews, which often brings with it a curvature of the spine and epilepsy-like symptoms in times of stress. Mendelssohn was treated with China bark, blood lettings on the foot, leeches applied to the ears, enemas, foot baths, lemonade and mainly vegetarian food. “No mental stress whatsoever” was ordered. However, although he remained subject to periods of setback, he eventually recovered sufficiently to write the major works of his later career. Death Mendelssohn died on 4 January 1786 as the result (it was thought at the time) of a cold contracted while carrying a manuscript (his reply to Jacobi, titled To Lessing's Friends (An die Freunde Lessings)) to his publishers on New Year's Eve; Jacobi was held by some to have been responsible for his death. He was buried in the Jewish Cemetery of Berlin. The translation of the Hebrew inscription
