Emily Blackwell. Inspired by this research, du Bois-Reymond began exploring the electrical properties of animal tissues, particularly focusing on muscles and nerves. His early work, especially his doctoral thesis on electric fishes, laid the foundation for his lifelong research into the electrical activity of living organisms. His investigation into electric fishes and animal electricity marked a significant leap in understanding how electricity played a vital role in physiological processes.

The study of these phenomena led him to hypothesize that muscle and nerve cells generated electrical currents as part of their normal function. This was groundbreaking at the time because the role of electricity in biological systems was not fully understood.

This work is widely regarded as one of the most important contributions to the field of electrophysiology. In it, du Bois-Reymond systematically described the electrical properties of muscle and nerve cells, offering both experimental data and theoretical models to explain bioelectricity. It established that electrical currents within nerves and muscles were central to physiological processes, particularly in communication between different parts of the nervous system and in muscle contraction.

This work was pivotal in establishing the field of electrophysiology and set the stage for later discoveries in neurobiology. Several contemporary physiologists, most notably Ludimar Hermann, criticized his ideas. Hermann argued that living tissues do not generate electric currents unless they are injured. This explanation proved to be accurate and is now the accepted model for understanding action potentials in excitable cells.

Although du Bois-Reymond is best known for his work on bioelectricity, he made important contributions to other areas of physiology as well. His research interests extended to various phenomena that could be studied using physical methods, including:. He held this position until his death in During his tenure, he became one of the most influential physiologists of his time, both as a researcher and a teacher.

Du Bois-Reymond was instrumental in establishing Berlin as a leading center for physiological research in the 19th century. Download as PDF Printable version. In other projects.

Du Bois-Reymond was a self-proclaimed atheist but more through intimate conviction than logical necessity. In the sixties Britain and France and Germany entered the age of Doubt, in the singular and with a capital D.

This was not quite fair. As a descendant of immigrants, du Bois-Reymond always felt a bit at odds with his surroundings. He had grown up speaking French, his wife was from England, and he counted Jews and foreigners among his closest friends. Even his connections to the Prussian crown prince and princess disaffected him from the regime. Du Bois-Reymond supported women, defended minorities, and attacked superstition; he warned against the dangers of power, wealth, and faith; and he stood up to Bismarck in matters of principle.

His example reminds us that patriots in Imperial Germany could be cosmopolitan critics as well as chauvinist reactionaries. He once joked to his wife that Prussian officers assumed that anyone of his eminence was an intimate of the government who regularly conversed with the Kaiser. He might have told them that he had introduced the engineer Werner Siemens to the mechanic Johann Georg Halske, or that he had launched the career of the physicist John Tyndall, or that he had sponsored the photography of Julia Margaret Cameron, or that he could recite poetry by Goethe and Hugo that he had seen in manuscript, but he was too polite to do more than excuse himself.

Most of his life he worked in obscurity, although every so often a keen observer would perceive the significance of his methods. Soon we shall have reached the point where every barber will use it and, when shaving you, will ask: Would you like to be stethoscoped, Sir? Then someone else will invent an instrument for listening to the beats of the brain.

That will make a tremendous stir, until, in fifty years, every barber can do it. Then in a barbershop, when one has had a haircut and a shave and has been stethoscoped for by then it will be very common the barber will ask: Perhaps you would also like me to listen to your brain-beats? Detecting brain-beats is not yet common practice in barbering, but it is in medicine.

In this respect Kierkegaard was right: The march of technology has been steady to the point of routine. But success is not a category of analysis any more than failure. To make sense of why du Bois-Reymond devoted the whole of his scientific career to one problem, it helps to understand his deepest motivations.
