Wilshire Boulevard runs like an artery through Los Angeles, stretching 16 miles from downtown to the Pacific Ocean. It's named after Henry Gaylord Wilshire, an influential real estate developer who once marketed a strange 1920s invention called the Ionaco, an electric healing belt. According to Wilshire's advertisements, the device was plugged into a household light socket and worn around the body, where it was said to improve the blood and increase oxygen in the body, restoring the user to health. It was promoted as a cure for a wide range of diseases, including cancer, diabetes, tuberculosis, and arthritis. Medical experts later dismissed it as quackery, but that didn't stop people from buying it. Wilshire sold more than 50,000 belts. It's easy to laugh at something like the electric healing belt. But there's a deeper reason people bought them: Wounded people long for healing.
