be the foundational text of pediatric cardiology as an independent field. The book was expanded into two volumes for a second edition published in 1960. Taussig later became an associate professor at the Johns Hopkins School of Medicine; she was promoted to full professor in 1959. At the time, she was only the second woman to reach full professor status at the university. She continued to serve as the director of the Harriet Lane Home (the children's treatment and research centre at Johns Hopkins) until her retirement in 1963. Most paediatric clinics at the time focussed on rheumatic fever, which was the major source of child mortality, but because of Taussig's experience, the Harriet Lane Home was also able to provide specialist care for children with congenital heart disease. It became a world-leading centre that aspiring surgeons flocked to. Together with the cardiologist Richard Bing, Taussig was in 1949 the first to describe a heart condition now known as Taussig-Bing syndrome. This is the second most common type of double-outlet right ventricle (DORV), a set of rare congenital heart conditions in which the aorta, which is supposed to carry oxygen-rich blood from the left ventricle of the heart, instead is connected to the right ventricle and supplies oxygen-poor blood to the body. Several alternative methods for surgically correcting this defect have been tried over the decades since the problem was first described, and survival rates following surgical intervention are greatly improved in recent decades. Banning of thalidomide Around 1960, many more babies than usual began to be born in Germany, Belgium and the Netherlands with phocomelia, a previously very rare condition in which limbs are absent or small and abnormally formed. The German paediatrician Widukind Lenz was the first to draw a link to the increasing frequency of this condition and thalidomide, a drug which was a popular sleeping medication at the time with the trade name Softenon, and was often taken by pregnant women to counter morning sickness. However, when it is taken between days 35 and 49 of a pregnancy, it blocks normal limb development and causes phocomelia. After hearing about this issue from one of her students in January 1962, Taussig travelled to Germany and examined some of these children for herself. She reached the same conclusion as Lenz: that thalidomide taken during pregnancy was causing phocomelia. She flew back to America and launched a campaign to
