In the final years of his life, Marx suffered repeated attacks of bronchitis and other illnesses. On doctor’s orders, he spent weeks on end convalescing by the sea, forbidden to exert himself. In the past, most biographers have passed over this period of Marx’s life very briefly, treating it as barren and unproductive. They can be forgiven for doing so, they had little to go on. Marx published very little in these years, and only a few of his letters were known. This situation has changed dramatically in recent years.
