Darwin's grandfather

[Dink Beaver]

"One treatment that became popular in the 1700s was the Swinging Chair, or rotational therapy. With this therapy, developed by Charles Darwin’s grandfather Erasmus, was based on his observations of children spinning themselves in order to induce vertigo, resulting in laughter. Darwin believed that this could work with an adult as well, and developed a “rotational chair,” where a person was placed in a chair, often with a box around that head or body to impede their sight, and then spun by hand until they experienced vertigo, sedation, nausea and vomiting or uncontrollable bowel movements. It was co-signed as a treatment by Dr. Benjamin Rush, the “Father of American Psychiatry,” and so rose to popularity in both the US and England. It was reportedly very effective – as a threat – in sedating unruly patients."
