Siegmund Mayer's Human Design Chart
2/4 Sacral GeneratorGerman physiologist and histologist who made several important contributions particularly concerning the physiology of the heart and vessels, respiration and intestines. He was one of the first to describe chromaffin cells in the sympathetic nerve, and with Ewald Hering and Ludwig Traube, his name is associated with “Traube–Hering–Mayer waves”, a phenomenon that deals with rhythmic variations in arterial blood pressure.
In addition to his scholarly papers published in scientific journals, he made contributions to Salomon Stricker’s Handbuch der Lehre von den Geweben des Menschen und der Thiere (1872) and to Ludimar Hermann’s Handbuch der Physiologie (1879). He was also the author of Histologisches Taschenbuch (1887).
