2014

In 1964, a few years after the thalidomide tragedy, the National Board of Health and Welfare in Sweden decided to start a register of congenital malformations for surveillance purposes. Together with Jan Winberg, pediatrician, I was tasked with arranging and running the register which I continued with until 1997, a third of a century. Since then I have worked with the National Board of Health on a free-lance basis. In 2014, I will have been working within the field of reproductive epidemiology for 50 years.
