Nils Adamsson

Nils Adamsson, known as the "Gummikungen" (Rubber King), was a Swedish entrepreneur who operated AB Nils Adamssons Sjukvårdsaffär, a healthcare and contraceptive business. He, along with his wife Karin Adamsson, advocated for birth control, free abortion, and sexual enjoyment. Their company, starting in the early 20th century, sold condoms and other "precautionary items" through a post-order firm named 'Nyhetsmagasinet' and later a shop, contributing to the advancement of family planning. Their activities led to legal issues, including imprisonment for promoting contraception, which they circumvented through marketing strategies like advertising in working-class newspapers. The business evolved over time, expanding into multiple branches and a post-order service.
